+
+    Description:        Whenever a property is added whose name is an array
+                        index, the length property is changed, if necessary,
+                        to be one more than the numeric value of that array
+                        index; and whenever the length property is changed,
+                        every property whose name is an array index whose value
+                        is not smaller  than the new length is automatically
+                        deleted.  This constraint applies only to the Array
+                        object itself, and is unaffected by length or array
+                        index properties that may be inherited from its
+                        prototype.

+                        the same arguments.
+
+                        An array is created and returned as if by the
+                        expression new Array(len).

+                        given two or more arguments.
+
+                        The [[Prototype]] property of the newly constructed
+                        object is set to the original Array prototype object,
+                        the one that is the initial value of Array.prototype(0)
+                        (15.4.3.1).
+

+                        is set to "Array".
+
+                        If the argument len is a number, then the length
+                        property  of the newly constructed object is set to
+                        ToUint32(len).
+
+                        If the argument len is not a number, then the length
+                        property of the newly constructed object is set to 1
+                        and the 0 property of the newly constructed object is
+                        set to len.

+    File Name:          15.4.4.3-1.js
+    ECMA Section:       15.4.4.3-1 Array.prototype.reverse()
+    Description:
+
+    The elements of the array are rearranged so as to reverse their order.
+    This object is returned as the result of the call.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+   3.   Compute floor(Result(2)/2).
+   4.   Let k be 0.
+   5.   If k equals Result(3), return this object.
+   6.   Compute Result(2)k1.
+   7.   Call ToString(k).
+   8.   ToString(Result(6)).
+   9.   Call the [[Get]] method of this object with argument Result(7).
+  10.   Call the [[Get]] method of this object with argument Result(8).
+  11.   If this object has a property named by Result(8), go to step 12; but
+        if this object has no property named by Result(8), then go to either
+        step 12 or step 14, depending on the implementation.
+  12.   Call the [[Put]] method of this object with arguments Result(7) and
+        Result(10).
+  13.   Go to step 15.
+  14.   Call the [[Delete]] method on this object, providing Result(7) as the
+        name of the property to delete.
+  15.   If this object has a property named by Result(7), go to step 16; but if
+        this object has no property named by Result(7), then go to either step 16
+        or step 18, depending on the implementation.
+  16.   Call the [[Put]] method of this object with arguments Result(8) and
+        Result(9).
+  17.   Go to step 19.
+  18.   Call the [[Delete]] method on this object, providing Result(8) as the
+        name of the property to delete.
+  19.   Increase k by 1.
+  20.   Go to step 5.
+
+Note that the reverse function is intentionally generic; it does not require
+that its this value be an Array object. Therefore it can be transferred to other
+kinds of objects for use as a method. Whether the reverse function can be applied
+successfully to a host object is implementation dependent.
+
+    Note:   Array.prototype.reverse allows some flexibility in implementation
+    regarding array indices that have not been populated. This test covers the
+    cases in which unpopulated indices are not deleted, since the JavaScript
+    implementation does not delete uninitialzed indices.

+    File Name:          15.4.4.3-1.js
+    ECMA Section:       15.4.4.3-1 Array.prototype.reverse()
+    Description:
+
+    The elements of the array are rearranged so as to reverse their order.
+    This object is returned as the result of the call.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+   3.   Compute floor(Result(2)/2).
+   4.   Let k be 0.
+   5.   If k equals Result(3), return this object.
+   6.   Compute Result(2)k1.
+   7.   Call ToString(k).
+   8.   ToString(Result(6)).
+   9.   Call the [[Get]] method of this object with argument Result(7).
+  10.   Call the [[Get]] method of this object with argument Result(8).
+  11.   If this object has a property named by Result(8), go to step 12; but
+        if this object has no property named by Result(8), then go to either
+        step 12 or step 14, depending on the implementation.
+  12.   Call the [[Put]] method of this object with arguments Result(7) and
+        Result(10).
+  13.   Go to step 15.
+  14.   Call the [[Delete]] method on this object, providing Result(7) as the
+        name of the property to delete.
+  15.   If this object has a property named by Result(7), go to step 16; but if
+        this object has no property named by Result(7), then go to either step 16
+        or step 18, depending on the implementation.
+  16.   Call the [[Put]] method of this object with arguments Result(8) and
+        Result(9).
+  17.   Go to step 19.
+  18.   Call the [[Delete]] method on this object, providing Result(8) as the
+        name of the property to delete.
+  19.   Increase k by 1.
+  20.   Go to step 5.
+
+Note that the reverse function is intentionally generic; it does not require
+that its this value be an Array object. Therefore it can be transferred to other
+kinds of objects for use as a method. Whether the reverse function can be applied
+successfully to a host object is implementation dependent.
+
+    Note:   Array.prototype.reverse allows some flexibility in implementation
+    regarding array indices that have not been populated. This test covers the
+    cases in which unpopulated indices are not deleted, since the JavaScript
+    implementation does not delete uninitialzed indices.

+    File Name:          15.4.4.5.js
+    ECMA Section:       Array.prototype.sort(comparefn)
+    Description:
+
+    This test file tests cases in which the compare function is not supplied.
+
+    The elements of this array are sorted. The sort is not necessarily stable.
+    If comparefn is provided, it should be a function that accepts two arguments
+    x and y and returns a negative value if x < y, zero if x = y, or a positive
+    value if x > y.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+        1.  Perform an implementation-dependent sequence of calls to the
+        [[Get]] , [[Put]], and [[Delete]] methods of this object and
+        toSortCompare (described below), where the first argument for each call
+            to [[Get]], [[Put]] , or [[Delete]] is a nonnegative integer less
+            than Result(2) and where the arguments for calls to SortCompare are
+            results of previous calls to the [[Get]] method. After this sequence
+            is complete, this object must have the following two properties.
+            (1) There must be some mathematical permutation of the nonnegative
+            integers less than Result(2), such that for every nonnegative integer
+            j less than Result(2), if property old[j] existed, then new[(j)] is
+            exactly the same value as old[j],. but if property old[j] did not exist,
+            then new[(j)] either does not exist or exists with value undefined.
+            (2) If comparefn is not supplied or is a consistent comparison
+            function for the elements of this array, then for all nonnegative
+            integers j and k, each less than Result(2), if old[j] compares less
+            than old[k] (see SortCompare below), then (j) < (k). Here we use the
+            notation old[j] to refer to the hypothetical result of calling the [
+            [Get]] method of this object with argument j before this step is
+            executed, and the notation new[j] to refer to the hypothetical result
+            of calling the [[Get]] method of this object with argument j after this
+            step has been completely executed. A function is a consistent
+            comparison function for a set of values if (a) for any two of those
+            values (possibly the same value) considered as an ordered pair, it
+            always returns the same value when given that pair of values as its
+            two arguments, and the result of applying ToNumber to this value is
+            not NaN; (b) when considered as a relation, where the pair (x, y) is
+            considered to be in the relation if and only if applying the function
+            to x and y and then applying ToNumber to the result produces a
+            negative value, this relation is a partial order; and (c) when
+            considered as a different relation, where the pair (x, y) is considered
+            to be in the relation if and only if applying the function to x and y
+            and then applying ToNumber to the result produces a zero value (of either
+            sign), this relation is an equivalence relation. In this context, the
+            phrase "x compares less than y" means applying Result(2) to x and y and
+            then applying ToNumber to the result produces a negative value.
+    3.Return this object.
+
+    When the SortCompare operator is called with two arguments x and y, the following steps are taken:
+       1.If x and y are both undefined, return +0.
+       2.If x is undefined, return 1.
+       3.If y is undefined, return 1.
+       4.If the argument comparefn was not provided in the call to sort, go to step 7.
+       5.Call comparefn with arguments x and y.
+       6.Return Result(5).
+       7.Call ToString(x).
+       8.Call ToString(y).
+       9.If Result(7) < Result(8), return 1.
+      10.If Result(7) > Result(8), return 1.
+      11.Return +0.
+
+Note that, because undefined always compared greater than any other value, undefined and nonexistent
+property values always sort to the end of the result. It is implementation-dependent whether or not such
+properties will exist or not at the end of the array when the sort is concluded.
+
+Note that the sort function is intentionally generic; it does not require that its this value be an Array object.
+Therefore it can be transferred to other kinds of objects for use as a method. Whether the sort function can be
+applied successfully to a host object is implementation dependent .

+    File Name:          15.4.4.5-2.js
+    ECMA Section:       Array.prototype.sort(comparefn)
+    Description:
+
+    This test file tests cases in which the compare function is supplied.
+    In this cases, the sort creates a reverse sort.
+
+    The elements of this array are sorted. The sort is not necessarily stable.
+    If comparefn is provided, it should be a function that accepts two arguments
+    x and y and returns a negative value if x < y, zero if x = y, or a positive
+    value if x > y.
+
+   1.   Call the [[Get]] method of this object with argument "length".
+   2.   Call ToUint32(Result(1)).
+        1.  Perform an implementation-dependent sequence of calls to the
+        [[Get]] , [[Put]], and [[Delete]] methods of this object and
+        toSortCompare (described below), where the first argument for each call
+            to [[Get]], [[Put]] , or [[Delete]] is a nonnegative integer less
+            than Result(2) and where the arguments for calls to SortCompare are
+            results of previous calls to the [[Get]] method. After this sequence
+            is complete, this object must have the following two properties.
+            (1) There must be some mathematical permutation of the nonnegative
+            integers less than Result(2), such that for every nonnegative integer
+            j less than Result(2), if property old[j] existed, then new[(j)] is
+            exactly the same value as old[j],. but if property old[j] did not exist,
+            then new[(j)] either does not exist or exists with value undefined.
+            (2) If comparefn is not supplied or is a consistent comparison
+            function for the elements of this array, then for all nonnegative
+            integers j and k, each less than Result(2), if old[j] compares less
+            than old[k] (see SortCompare below), then (j) < (k). Here we use the
+            notation old[j] to refer to the hypothetical result of calling the [
+            [Get]] method of this object with argument j before this step is
+            executed, and the notation new[j] to refer to the hypothetical result
+            of calling the [[Get]] method of this object with argument j after this
+            step has been completely executed. A function is a consistent
+            comparison function for a set of values if (a) for any two of those
+            values (possibly the same value) considered as an ordered pair, it
+            always returns the same value when given that pair of values as its
+            two arguments, and the result of applying ToNumber to this value is
+            not NaN; (b) when considered as a relation, where the pair (x, y) is
+            considered to be in the relation if and only if applying the function
+            to x and y and then applying ToNumber to the result produces a
+            negative value, this relation is a partial order; and (c) when
+            considered as a different relation, where the pair (x, y) is considered
+            to be in the relation if and only if applying the function to x and y
+            and then applying ToNumber to the result produces a zero value (of either
+            sign), this relation is an equivalence relation. In this context, the
+            phrase "x compares less than y" means applying Result(2) to x and y and
+            then applying ToNumber to the result produces a negative value.
+    3.Return this object.
+
+    When the SortCompare operator is called with two arguments x and y, the following steps are taken:
+       1.If x and y are both undefined, return +0.
+       2.If x is undefined, return 1.
+       3.If y is undefined, return 1.
+       4.If the argument comparefn was not provided in the call to sort, go to step 7.
+       5.Call comparefn with arguments x and y.
+       6.Return Result(5).
+       7.Call ToString(x).
+       8.Call ToString(y).
+       9.If Result(7) < Result(8), return 1.
+      10.If Result(7) > Result(8), return 1.
+      11.Return +0.
+
+Note that, because undefined always compared greater than any other value, undefined and nonexistent
+property values always sort to the end of the result. It is implementation-dependent whether or not such
+properties will exist or not at the end of the array when the sort is concluded.
+
+Note that the sort function is intentionally generic; it does not require that its this value be an Array object.
+Therefore it can be transferred to other kinds of objects for use as a method. Whether the sort function can be
+applied successfully to a host object is implementation dependent .

+    Description:        If this boolean value is true, then the string "true"

+    ECMA Section:       Properties of the Boolean Prototype Object
+    Description:
+    The Boolean prototype object is itself a Boolean object (its [[Class]] is "
+    Boolean") whose value is false.
+
+    The value of the internal [[Prototype]] property of the Boolean prototype
+    object is the Object prototype object (15.2.3.1).
+
+    In following descriptions of functions that are properties of the Boolean
+    prototype object, the phrase "this Boolean object" refers to the object that
+    is the this value for the invocation of the function; it is an error if
+    this does not refer to an object for which the value of the internal
+    [[Class]] property is "Boolean". Also, the phrase "this boolean value"
+    refers to the boolean value represented by this Boolean object, that is,
+    the value of the internal [[Value]] property of this Boolean object.

+    ECMA Section:       15.9.3.1 new Date (year, month, date, hours, minutes, seconds, ms)
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial value of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object
+                        is set as follows:
+                        1. Call ToNumber(year)
+                        2. Call ToNumber(month)
+                        3. Call ToNumber(date)
+                        4. Call ToNumber(hours)
+                        5. Call ToNumber(minutes)
+                        6. Call ToNumber(seconds)
+                        7. Call ToNumber(ms)
+                        8.  If Result(1) is NaN and 0 <= ToInteger(Result(1)) <=
+                            99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+                            Result(8) is Result(1)
+                        9.  Compute MakeDay(Result(8), Result(2), Result(3)
+                        10. Compute MakeTime(Result(4), Result(5), Result(6),
+                            Result(7)
+                        11. Compute MakeDate(Result(9), Result(10))
+                        12. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(UTC(Result(11))).
+
+
+                        This tests the returned value of a newly constructed
+                        Date object.

+    File Name:          15.9.3.1.js
+    ECMA Section:       15.9.3.1 new Date (year, month, date, hours, minutes, seconds, ms)
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial value of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object
+                        is set as follows:
+                        1. Call ToNumber(year)
+                        2. Call ToNumber(month)
+                        3. Call ToNumber(date)
+                        4. Call ToNumber(hours)
+                        5. Call ToNumber(minutes)
+                        6. Call ToNumber(seconds)
+                        7. Call ToNumber(ms)
+                        8.  If Result(1) is NaN and 0 <= ToInteger(Result(1)) <=
+                            99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+                            Result(8) is Result(1)
+                        9.  Compute MakeDay(Result(8), Result(2), Result(3)
+                        10. Compute MakeTime(Result(4), Result(5), Result(6),
+                            Result(7)
+                        11. Compute MakeDate(Result(9), Result(10))
+                        12. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(UTC(Result(11))).
+
+
+                        This tests the returned value of a newly constructed
+                        Date object.

+    ECMA Section:       15.9.3.1 new Date (year, month, date, hours, minutes, seconds, ms)
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial value of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object
+                        is set as follows:
+                        1. Call ToNumber(year)
+                        2. Call ToNumber(month)
+                        3. Call ToNumber(date)
+                        4. Call ToNumber(hours)
+                        5. Call ToNumber(minutes)
+                        6. Call ToNumber(seconds)
+                        7. Call ToNumber(ms)
+                        8.  If Result(1) is NaN and 0 <= ToInteger(Result(1)) <=
+                            99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+                            Result(8) is Result(1)
+                        9.  Compute MakeDay(Result(8), Result(2), Result(3)
+                        10. Compute MakeTime(Result(4), Result(5), Result(6),
+                            Result(7)
+                        11. Compute MakeDate(Result(9), Result(10))
+                        12. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(UTC(Result(11))).
+
+
+                        This tests the returned value of a newly constructed
+                        Date object.

+    File Name:          15.9.3.1.js
+    ECMA Section:       15.9.3.1 new Date (year, month, date, hours, minutes, seconds, ms)
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial value of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object
+                        is set as follows:
+                        1. Call ToNumber(year)
+                        2. Call ToNumber(month)
+                        3. Call ToNumber(date)
+                        4. Call ToNumber(hours)
+                        5. Call ToNumber(minutes)
+                        6. Call ToNumber(seconds)
+                        7. Call ToNumber(ms)
+                        8.  If Result(1)is NaN and 0 <= ToInteger(Result(1)) <=
+                            99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+                            Result(8) is Result(1)
+                        9.  Compute MakeDay(Result(8), Result(2), Result(3)
+                        10. Compute MakeTime(Result(4), Result(5), Result(6),
+                            Result(7)
+                        11. Compute MakeDate(Result(9), Result(10))
+                        12. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(UTC(Result(11))).
+
+
+                        This tests the returned value of a newly constructed
+                        Date object.

+    File Name:          15.9.3.1.js
+    ECMA Section:       15.9.3.1 new Date (year, month, date, hours, minutes, seconds, ms)
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial value of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object
+                        is set as follows:
+                        1. Call ToNumber(year)
+                        2. Call ToNumber(month)
+                        3. Call ToNumber(date)
+                        4. Call ToNumber(hours)
+                        5. Call ToNumber(minutes)
+                        6. Call ToNumber(seconds)
+                        7. Call ToNumber(ms)
+                        8.  If Result(1)is NaN and 0 <= ToInteger(Result(1)) <=
+                            99, Result(8) is 1900+ToInteger(Result(1)); otherwise,
+                            Result(8) is Result(1)
+                        9.  Compute MakeDay(Result(8), Result(2), Result(3)
+                        10. Compute MakeTime(Result(4), Result(5), Result(6),
+                            Result(7)
+                        11. Compute MakeDate(Result(9), Result(10))
+                        12. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(UTC(Result(11))).
+
+
+                        This tests the returned value of a newly constructed
+                        Date object.

+    ECMA Section:       15.9.3.8 The Date Constructor
+                        new Date( value )
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial valiue of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object is
+                        set to "Date".
+
+                        The [[Value]] property of the newly constructed object is
+                        set as follows:
+
+                        1. Call ToPrimitive(value)
+                        2. If Type( Result(1) ) is String, then go to step 5.
+                        3. Let V be  ToNumber( Result(1) ).
+                        4. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(V) and return.
+                        5. Parse Result(1) as a date, in exactly the same manner
+                            as for the parse method.  Let V be the time value for
+                            this date.
+                        6. Go to step 4.

+    ECMA Section:       15.9.3.8 The Date Constructor
+                        new Date( value )
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial valiue of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object is
+                        set to "Date".
+
+                        The [[Value]] property of the newly constructed object is
+                        set as follows:
+
+                        1. Call ToPrimitive(value)
+                        2. If Type( Result(1) ) is String, then go to step 5.
+                        3. Let V be  ToNumber( Result(1) ).
+                        4. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(V) and return.
+                        5. Parse Result(1) as a date, in exactly the same manner
+                            as for the parse method.  Let V be the time value for
+                            this date.
+                        6. Go to step 4.

+    ECMA Section:       15.9.3.8 The Date Constructor
+                        new Date( value )
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial valiue of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object is
+                        set to "Date".
+
+                        The [[Value]] property of the newly constructed object is
+                        set as follows:
+
+                        1. Call ToPrimitive(value)
+                        2. If Type( Result(1) ) is String, then go to step 5.
+                        3. Let V be  ToNumber( Result(1) ).
+                        4. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(V) and return.
+                        5. Parse Result(1) as a date, in exactly the same manner
+                            as for the parse method.  Let V be the time value for
+                            this date.
+                        6. Go to step 4.

+                        new Date( value )
+    Description:        The [[Prototype]] property of the newly constructed
+                        object is set to the original Date prototype object,
+                        the one that is the initial valiue of Date.prototype.
+
+                        The [[Class]] property of the newly constructed object is
+                        set to "Date".
+
+                        The [[Value]] property of the newly constructed object is
+                        set as follows:
+
+                        1. Call ToPrimitive(value)
+                        2. If Type( Result(1) ) is String, then go to step 5.
+                        3. Let V be  ToNumber( Result(1) ).
+                        4. Set the [[Value]] property of the newly constructed
+                            object to TimeClip(V) and return.
+                        5. Parse Result(1) as a date, in exactly the same manner
+                            as for the parse method.  Let V be the time value for
+                            this date.
+                        6. Go to step 4.

+    Description:
+    This function returns a string value. The contents of the string are

+    convenient, human-readable form in the current time zone.
+
+    The toString function is not generic; it generates a runtime error if its

+    other kinds of objects for use as a method.
+
+
+    This verifies that calling toString on an object that is not a string
+    generates a runtime error.

+    ECMA Section:       15.9.5.26 Date.prototype.setSeconds(sec [,ms])
+    Description:
+
+    If ms is not specified, this behaves as if ms were specified with the
+    value getMilliseconds( ).
+
+    1.  Let t be the result of LocalTime(this time value).
+    2.  Call ToNumber(sec).
+    3.  If ms is not specified, compute msFromTime(t); otherwise, call
+        ToNumber(ms).
+    4.  Compute MakeTime(HourFromTime(t), MinFromTime(t), Result(2),
+        Result(3)).
+    5.  Compute UTC(MakeDate(Day(t), Result(4))).
+    6.  Set the [[Value]] property of the this value to TimeClip(Result(5)).
+    7.  Return the value of the [[Value]] property of the this value.

+    ECMA Section:       15.9.5.28 Date.prototype.setMinutes(min [, sec [, ms ]] )
+    Description:
+    If sec is not specified, this behaves as if sec were specified with the
+    value getSeconds ( ).
+
+    If ms is not specified, this behaves as if ms were specified with the
+    value getMilliseconds( ).
+
+    1.  Let t be the result of LocalTime(this time value).
+    2.  Call ToNumber(min).
+    3.  If sec is not specified, compute SecFromTime(t); otherwise, call ToNumber(sec).
+    4.  If ms is not specified, compute msFromTime(t); otherwise, call ToNumber(ms).
+    5.  Compute MakeTime(HourFromTime(t), Result(2), Result(3), Result(4)).
+    6.  Compute UTC(MakeDate(Day(t), Result(5))).
+    7.  Set the [[Value]] property of the this value to TimeClip(Result(6)).
+    8.  Return the value of the [[Value]] property of the this value.

+    ECMA Section:       15.9.5.29 Date.prototype.setUTCMinutes(min [, sec [, ms ]] )
+    Description:
+    If sec is not specified, this behaves as if sec were specified with the
+    value getUTCSeconds ( ).
+
+    If ms is not specified, this behaves as if ms were specified with the value
+    getUTCMilliseconds( ).
+
+    1.  Let t be this time value.
+    2.  Call ToNumber(min).
+    3.  If sec is not specified, compute SecFromTime(t); otherwise, call
+        ToNumber(sec).
+    4.  If ms is not specified, compute msFromTime(t); otherwise, call
+        ToNumber(ms).
+    5.  Compute MakeTime(HourFromTime(t), Result(2), Result(3), Result(4)).
+    6.  Compute MakeDate(Day(t), Result(5)).
+    7.  Set the [[Value]] property of the this value to TimeClip(Result(6)).
+    8.  Return the value of the [[Value]] property of the this value.

+    ECMA Section:       15.9.5.30 Date.prototype.setHours(hour [, min [, sec [, ms ]]] )
+    Description:
+    If min is not specified, this behaves as if min were specified with the
+    value getMinutes( ). If sec is not specified, this behaves as if sec were
+    specified with the value getSeconds ( ). If ms is not specified, this
+    behaves as if ms were specified with the value getMilliseconds( ).
+
+    1.  Let t be the result of LocalTime(this time value).
+    2.  Call ToNumber(hour).
+    3.  If min is not specified, compute MinFromTime(t); otherwise, call
+        ToNumber(min).
+    4.  If sec is not specified, compute SecFromTime(t); otherwise, call
+        ToNumber(sec).
+    5.  If ms is not specified, compute msFromTime(t); otherwise, call
+        ToNumber(ms).
+    6.  Compute MakeTime(Result(2), Result(3), Result(4), Result(5)).
+    7.  Compute UTC(MakeDate(Day(t), Result(6))).
+    8.  Set the [[Value]] property of the this value to TimeClip(Result(7)).
+    9.  Return the value of the [[Value]] property of the this value.

+    ECMA Section:       15.9.5.34 Date.prototype.setMonth(mon [, date ] )
+    Description:
+    If date is not specified, this behaves as if date were specified with the
+    value getDate( ).
+
+    1.  Let t be the result of LocalTime(this time value).
+    2.  Call ToNumber(date).
+    3.  If date is not specified, compute DateFromTime(t); otherwise, call ToNumber(date).
+    4.  Compute MakeDay(YearFromTime(t), Result(2), Result(3)).
+    5.  Compute UTC(MakeDate(Result(4), TimeWithinDay(t))).
+    6.  Set the [[Value]] property of the this value to TimeClip(Result(5)).
+    7.  Return the value of the [[Value]] property of the this value.

+    specified with the value getDate( ).
+
+   1.   Let t be the result of LocalTime(this time value); but if this time
+        value is NaN, let t be +0.
+   2.   Call ToNumber(year).
+   3.   If mon is not specified, compute MonthFromTime(t); otherwise, call
+        ToNumber(mon).
+   4.   If date is not specified, compute DateFromTime(t); otherwise, call
+        ToNumber(date).
+   5.   Compute MakeDay(Result(2), Result(3), Result(4)).
+   6.   Compute UTC(MakeDate(Result(5), TimeWithinDay(t))).
+   7.   Set the [[Value]] property of the this value to TimeClip(Result(6)).

+    ECMA Section:       15.9.5.36 Date.prototype.setFullYear(year [, mon [, date ]] )
+    Description:
+
+    If mon is not specified, this behaves as if mon were specified with the
+    value getMonth( ). If date is not specified, this behaves as if date were
+    specified with the value getDate( ).
+
+   1.   Let t be the result of LocalTime(this time value); but if this time
+        value is NaN, let t be +0.
+   2.   Call ToNumber(year).
+   3.   If mon is not specified, compute MonthFromTime(t); otherwise, call
+        ToNumber(mon).
+   4.   If date is not specified, compute DateFromTime(t); otherwise, call
+        ToNumber(date).
+   5.   Compute MakeDay(Result(2), Result(3), Result(4)).
+   6.   Compute UTC(MakeDate(Result(5), TimeWithinDay(t))).
+   7.   Set the [[Value]] property of the this value to TimeClip(Result(6)).
+   8.   Return the value of the [[Value]] property of the this value.

+    If mon is not specified, this behaves as if mon were specified with the
+    value getMonth( ). If date is not specified, this behaves as if date were
+    specified with the value getDate( ).
+
+   1.   Let t be the result of LocalTime(this time value); but if this time
+        value is NaN, let t be +0.
+   2.   Call ToNumber(year).
+   3.   If mon is not specified, compute MonthFromTime(t); otherwise, call
+        ToNumber(mon).
+   4.   If date is not specified, compute DateFromTime(t); otherwise, call
+        ToNumber(date).
+   5.   Compute MakeDay(Result(2), Result(3), Result(4)).
+   6.   Compute UTC(MakeDate(Result(5), TimeWithinDay(t))).
+   7.   Set the [[Value]] property of the this value to TimeClip(Result(6)).
+   8.   Return the value of the [[Value]] property of the this value.

+    ECMA Section:       15.9.5.37 Date.prototype.setUTCFullYear(year [, mon [, date ]] )
+    Description:
+
+    If mon is not specified, this behaves as if mon were specified with the
+    value getUTCMonth( ).  If date is not specified, this behaves as if date
+    were specified with the value getUTCDate( ).
+
+   1.   Let t be this time value; but if this time value is NaN, let t be +0.
+   2.   Call ToNumber(year).
+   3.   If mon is not specified, compute MonthFromTime(t); otherwise, call
+        ToNumber(mon).
+   4.   If date is not specified, compute DateFromTime(t); otherwise, call
+        ToNumber(date).
+   5.   Compute MakeDay(Result(2), Result(3), Result(4)).
+   6.   Compute MakeDate(Result(5), TimeWithinDay(t)).
+   7.   Set the [[Value]] property of the this value to TimeClip(Result(6)).
+   8.   Return the value of the [[Value]] property of the this value.

+
+    If mon is not specified, this behaves as if mon were specified with the

+    were specified with the value getUTCDate( ).
+
+   1.   Let t be this time value; but if this time value is NaN, let t be +0.
+   2.   Call ToNumber(year).
+   3.   If mon is not specified, compute MonthFromTime(t); otherwise, call
+        ToNumber(mon).
+   4.   If date is not specified, compute DateFromTime(t); otherwise, call
+        ToNumber(date).
+   5.   Compute MakeDay(Result(2), Result(3), Result(4)).
+   6.   Compute MakeDate(Result(5), TimeWithinDay(t)).
+   7.   Set the [[Value]] property of the this value to TimeClip(Result(6)).
+   8.   Return the value of the [[Value]] property of the this value.

+    this does not refer to an object for which the value of the internal
+    [[Class]] property is "Date". Also, the phrase "this time value" refers
+    to the number value for the time represented by this Date object, that is,
+    the value of the internal [[Value]] property of this Date object.

+    ECMA Section:       10.1.4 Scope Chain and Identifier Resolution
+    Description:
+    Every execution context has associated with it a scope chain. This is
+    logically a list of objects that are searched when binding an Identifier.
+    When control enters an execution context, the scope chain is created and
+    is populated with an initial set of objects, depending on the type of
+    code. When control leaves the execution context, the scope chain is
+    destroyed.
+
+    During execution, the scope chain of the execution context is affected
+    only by WithStatement. When execution enters a with block, the object
+    specified in the with statement is added to the front of the scope chain.
+    When execution leaves a with block, whether normally or via a break or
+    continue statement, the object is removed from the scope chain. The object
+    being removed will always be the first object in the scope chain.
+
+    During execution, the syntactic production PrimaryExpression : Identifier
+    is evaluated using the following algorithm:
+
+    1.  Get the next object in the scope chain. If there isn't one, go to step 5.
+    2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
+        the property.
+    3.  If Result(2) is true, return a value of type Reference whose base object
+        is Result(l) and whose property name is the Identifier.
+    4.  Go to step 1.
+    5.  Return a value of type Reference whose base object is null and whose
+        property name is the Identifier.
+    The result of binding an identifier is always a value of type Reference with
+    its member name component equal to the identifier string.

+    ECMA Section:       10.1.4 Scope Chain and Identifier Resolution
+    Description:
+    Every execution context has associated with it a scope chain. This is
+    logically a list of objects that are searched when binding an Identifier.
+    When control enters an execution context, the scope chain is created and
+    is populated with an initial set of objects, depending on the type of
+    code. When control leaves the execution context, the scope chain is
+    destroyed.
+
+    During execution, the scope chain of the execution context is affected
+    only by WithStatement. When execution enters a with block, the object
+    specified in the with statement is added to the front of the scope chain.
+    When execution leaves a with block, whether normally or via a break or
+    continue statement, the object is removed from the scope chain. The object
+    being removed will always be the first object in the scope chain.
+
+    During execution, the syntactic production PrimaryExpression : Identifier
+    is evaluated using the following algorithm:
+
+    1.  Get the next object in the scope chain. If there isn't one, go to step 5.
+    2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
+        the property.
+    3.  If Result(2) is true, return a value of type Reference whose base object
+        is Result(l) and whose property name is the Identifier.
+    4.  Go to step 1.
+    5.  Return a value of type Reference whose base object is null and whose
+        property name is the Identifier.
+    The result of binding an identifier is always a value of type Reference with
+    its member name component equal to the identifier string.

+    File Name:          10.1.4-9.js
+    ECMA Section:       10.1.4 Scope Chain and Identifier Resolution
+    Description:
+    Every execution context has associated with it a scope chain. This is
+    logically a list of objects that are searched when binding an Identifier.
+    When control enters an execution context, the scope chain is created and
+    is populated with an initial set of objects, depending on the type of
+    code. When control leaves the execution context, the scope chain is
+    destroyed.
+
+    During execution, the scope chain of the execution context is affected
+    only by WithStatement. When execution enters a with block, the object
+    specified in the with statement is added to the front of the scope chain.
+    When execution leaves a with block, whether normally or via a break or
+    continue statement, the object is removed from the scope chain. The object
+    being removed will always be the first object in the scope chain.
+
+    During execution, the syntactic production PrimaryExpression : Identifier
+    is evaluated using the following algorithm:
+
+    1.  Get the next object in the scope chain. If there isn't one, go to step 5.
+    2.  Call the [[HasProperty]] method of Result(l), passing the Identifier as
+        the property.
+    3.  If Result(2) is true, return a value of type Reference whose base object
+        is Result(l) and whose property name is the Identifier.
+    4.  Go to step 1.
+    5.  Return a value of type Reference whose base object is null and whose
+        property name is the Identifier.
+    The result of binding an identifier is always a value of type Reference with
+    its member name component equal to the identifier string.

+    File Name:          10.1.6
+    ECMA Section:       Activation Object
+    Description:
+
+    If the function object being invoked has an arguments property, let x be
+    the value of that property; the activation object is also given an internal
+    property [[OldArguments]] whose initial value is x; otherwise, an arguments
+    property is created for the function object but the activation object is
+    not given an [[OldArguments]] property. Next, arguments object described
+    below (the same one stored in the arguments property of the activation
+    object) is used as the new value of the arguments property of the function
+    object. This new value is installed even if the arguments property already
+    exists and has the ReadOnly attribute (as it will for native Function
+    objects). (These actions are taken to provide compatibility with a form of
+    program syntax that is now discouraged: to access the arguments object for
+    function f within the body of f by using the expression f.arguments.
+    The recommended way to access the arguments object for function f within
+    the body of f is simply to refer to the variable arguments.)

+    File Name:          10.1.8
+    ECMA Section:       Arguments Object
+    Description:
+
+    When control enters an execution context for declared function code,
+    anonymous code, or implementation-supplied code, an arguments object is
+    created and initialized as follows:
+
+    The [[Prototype]] of the arguments object is to the original Object
+    prototype object, the one that is the initial value of Object.prototype
+    (section 15.2.3.1).
+
+    A property is created with name callee and property attributes {DontEnum}.
+    The initial value of this property is the function object being executed.
+    This allows anonymous functions to be recursive.
+
+    A property is created with name length and property attributes {DontEnum}.
+    The initial value of this property is the number of actual parameter values
+    supplied by the caller.
+
+    For each non-negative integer, iarg, less than the value of the length
+    property, a property is created with name ToString(iarg) and property
+    attributes { DontEnum }. The initial value of this property is the value
+    of the corresponding actual parameter supplied by the caller. The first
+    actual parameter value corresponds to iarg = 0, the second to iarg = 1 and
+    so on. In the case when iarg is less than the number of formal parameters
+    for the function object, this property shares its value with the
+    corresponding property of the activation object. This means that changing
+    this property changes the corresponding property of the activation object
+    and vice versa. The value sharing mechanism depends on the implementation.

+    ECMA Section:       10.2.2 Eval Code
+    Description:
+
+    When control enters an execution context for eval code, the previous
+    active execution context, referred to as the calling context, is used to
+    determine the scope chain, the variable object, and the this value. If
+    there is no calling context, then initializing the scope chain, variable
+    instantiation, and determination of the this value are performed just as
+    for global code.
+
+    The scope chain is initialized to contain the same objects, in the same
+    order, as the calling context's scope chain.  This includes objects added
+    to the calling context's scope chain by WithStatement.
+
+    Variable instantiation is performed using the calling context's variable
+    object and using empty property attributes.
+
+    The this value is the same as the this value of the calling context.

+    Description:
+
+    The grammar for a ConditionalExpression in ECMAScript is a little bit
+    different from that in C and Java, which each allow the second
+    subexpression to be an Expression but restrict the third expression to
+    be a ConditionalExpression.  The motivation for this difference in
+    ECMAScript is to allow an assignment expression to be governed by either
+    arm of a conditional and to eliminate the confusing and fairly useless
+    case of a comma expression as the center expression.

+    be a ConditionalExpression.  The motivation for this difference in

+    case of a comma expression as the center expression.

+    3.  Evaluate AssignmentExpression.
+    4.  Call GetValue(Result(3)).
+    5.  Apply operator @ to Result(2) and Result(4).
+    6.  Call PutValue(Result(1), Result(5)).
+    7.  Return Result(5).

+    ECMA Section:       11.2.1 Property Accessors
+    Description:
+
+    Properties are accessed by name, using either the dot notation:
+                                MemberExpression . Identifier
+                                CallExpression . Identifier
+
+    or the bracket notation:    MemberExpression [ Expression ]
+                                CallExpression [ Expression ]
+
+    The dot notation is explained by the following syntactic conversion:
+                                MemberExpression . Identifier
+    is identical in its behavior to
+                                MemberExpression [ <identifier-string> ]
+    and similarly
+                                CallExpression . Identifier
+    is identical in its behavior to
+                                CallExpression [ <identifier-string> ]
+    where <identifier-string> is a string literal containing the same sequence
+    of characters as the Identifier.
+
+    The production MemberExpression : MemberExpression [ Expression ] is
+    evaluated as follows:
+
+    1.  Evaluate MemberExpression.
+    2.  Call GetValue(Result(1)).
+    3.  Evaluate Expression.
+    4.  Call GetValue(Result(3)).
+    5.  Call ToObject(Result(2)).
+    6.  Call ToString(Result(4)).
+    7.  Return a value of type Reference whose base object is Result(5) and
+        whose property name is Result(6).
+
+    The production CallExpression : CallExpression [ Expression ] is evaluated
+    in exactly the same manner, except that the contained CallExpression is
+    evaluated in step 1.

+    ECMA Section:       11.2.1 Property Accessors
+    Description:
+
+    Properties are accessed by name, using either the dot notation:
+                                MemberExpression . Identifier
+                                CallExpression . Identifier
+
+    or the bracket notation:    MemberExpression [ Expression ]
+                                CallExpression [ Expression ]
+
+    The dot notation is explained by the following syntactic conversion:
+                                MemberExpression . Identifier
+    is identical in its behavior to
+                                MemberExpression [ <identifier-string> ]
+    and similarly
+                                CallExpression . Identifier
+    is identical in its behavior to
+                                CallExpression [ <identifier-string> ]
+    where <identifier-string> is a string literal containing the same sequence
+    of characters as the Identifier.
+
+    The production MemberExpression : MemberExpression [ Expression ] is
+    evaluated as follows:
+
+    1.  Evaluate MemberExpression.
+    2.  Call GetValue(Result(1)).
+    3.  Evaluate Expression.
+    4.  Call GetValue(Result(3)).
+    5.  Call ToObject(Result(2)).
+    6.  Call ToString(Result(4)).
+    7.  Return a value of type Reference whose base object is Result(5) and
+        whose property name is Result(6).
+
+    The production CallExpression : CallExpression [ Expression ] is evaluated
+    in exactly the same manner, except that the contained CallExpression is
+    evaluated in step 1.

+    File Name:          11.2.1-5.js
+    ECMA Section:       11.2.1 Property Accessors
+    Description:
+
+    Properties are accessed by name, using either the dot notation:
+                                MemberExpression . Identifier
+                                CallExpression . Identifier
+
+    or the bracket notation:    MemberExpression [ Expression ]
+                                CallExpression [ Expression ]
+
+    The dot notation is explained by the following syntactic conversion:
+                                MemberExpression . Identifier
+    is identical in its behavior to
+                                MemberExpression [ <identifier-string> ]
+    and similarly
+                                CallExpression . Identifier
+    is identical in its behavior to
+                                CallExpression [ <identifier-string> ]
+    where <identifier-string> is a string literal containing the same sequence
+    of characters as the Identifier.
+
+    The production MemberExpression : MemberExpression [ Expression ] is
+    evaluated as follows:
+
+    1.  Evaluate MemberExpression.
+    2.  Call GetValue(Result(1)).
+    3.  Evaluate Expression.
+    4.  Call GetValue(Result(3)).
+    5.  Call ToObject(Result(2)).
+    6.  Call ToString(Result(4)).
+    7.  Return a value of type Reference whose base object is Result(5) and
+        whose property name is Result(6).
+
+    The production CallExpression : CallExpression [ Expression ] is evaluated
+    in exactly the same manner, except that the contained CallExpression is
+    evaluated in step 1.

+    2.Evaluate Arguments, producing an internal list of argument values
+        (section 0).

+    7.If Result(6) is an activation object, Result(7) is null. Otherwise, Result(7) is

+    Description:
+
+    11.3.2 Postfix decrement operator
+
+    The production MemberExpression : MemberExpression -- is evaluated as follows:
+    1.  Evaluate MemberExpression.
+    2.  Call GetValue(Result(1)).
+    3.  Call ToNumber(Result(2)).
+    4.  Subtract the value 1 from Result(3), using the same rules as for the -
+        operator (section 0).
+    5.  Call PutValue(Result(1), Result(4)).
+    6.  Return Result(3).

+    ECMA Section:       11.5.1 Applying the * operator
+    Description:
+
+    11.5.1 Applying the * operator
+
+    The * operator performs multiplication, producing the product of its
+    operands. Multiplication is commutative. Multiplication is not always
+    associative in ECMAScript, because of finite precision.
+
+    The result of a floating-point multiplication is governed by the rules
+    of IEEE 754 double-precision arithmetic:
+
+    If either operand is NaN, the result is NaN.
+    The sign of the result is positive if both operands have the same sign,
+    negative if the operands have different signs.
+    Multiplication of an infinity by a zero results in NaN.
+    Multiplication of an infinity by an infinity results in an infinity.
+    The sign is determined by the rule already stated above.
+    Multiplication of an infinity by a finite non-zero value results in a
+    signed infinity. The sign is determined by the rule already stated above.
+    In the remaining cases, where neither an infinity or NaN is involved, the
+    product is computed and rounded to the nearest representable value using IEEE
+    754 round-to-nearest mode. If the magnitude is too large to represent,
+    the result is then an infinity of appropriate sign. If the magnitude is
+    oo small to represent, the result is then a zero
+    of appropriate sign. The ECMAScript language requires support of gradual
+    underflow as defined by IEEE 754.

+    ECMA Section:       11.5.2 Applying the / operator
+    Description:
+
+    The / operator performs division, producing the quotient of its operands.
+    The left operand is the dividend and the right operand is the divisor.
+    ECMAScript does not perform integer division. The operands and result of all
+    division operations are double-precision floating-point numbers.
+    The result of division is determined by the specification of IEEE 754 arithmetic:
+
+      If either operand is NaN, the result is NaN.
+      The sign of the result is positive if both operands have the same sign, negative if the operands have different
+      signs.
+      Division of an infinity by an infinity results in NaN.
+      Division of an infinity by a zero results in an infinity. The sign is determined by the rule already stated above.
+      Division of an infinity by a non-zero finite value results in a signed infinity. The sign is determined by the rule
+      already stated above.
+      Division of a finite value by an infinity results in zero. The sign is determined by the rule already stated above.
+      Division of a zero by a zero results in NaN; division of zero by any other finite value results in zero, with the sign
+      determined by the rule already stated above.
+      Division of a non-zero finite value by a zero results in a signed infinity. The sign is determined by the rule
+      already stated above.
+      In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the quotient is computed and
+      rounded to the nearest representable value using IEEE 754 round-to-nearest mode. If the magnitude is too
+      large to represent, we say the operation overflows; the result is then an infinity of appropriate sign. If the
+      magnitude is too small to represent, we say the operation underflows and the result is a zero of the appropriate
+      sign. The ECMAScript language requires support of gradual underflow as defined by IEEE 754.

+    File Name:          11.5.3.js
+    ECMA Section:       11.5.3 Applying the % operator
+    Description:
+
+    The binary % operator is said to yield the remainder of its operands from
+    an implied division; the left operand is the dividend and the right operand
+    is the divisor. In C and C++, the remainder operator accepts only integral
+    operands, but in ECMAScript, it also accepts floating-point operands.
+
+    The result of a floating-point remainder operation as computed by the %
+    operator is not the same as the "remainder" operation defined by IEEE 754.
+    The IEEE 754 "remainder" operation computes the remainder from a rounding
+    division, not a truncating division, and so its behavior is not analogous
+    to that of the usual integer remainder operator. Instead the ECMAScript
+    language defines % on floating-point operations to behave in a manner
+    analogous to that of the Java integer remainder operator; this may be
+    compared with the C library function fmod.
+
+    The result of a ECMAScript floating-point remainder operation is determined by the rules of IEEE arithmetic:
+
+      If either operand is NaN, the result is NaN.
+      The sign of the result equals the sign of the dividend.
+      If the dividend is an infinity, or the divisor is a zero, or both, the result is NaN.
+      If the dividend is finite and the divisor is an infinity, the result equals the dividend.
+      If the dividend is a zero and the divisor is finite, the result is the same as the dividend.
+      In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the floating-point remainder r
+      from a dividend n and a divisor d is defined by the mathematical relation r = n (d * q) where q is an integer that
+      is negative only if n/d is negative and positive only if n/d is positive, and whose magnitude is as large as
+      possible without exceeding the magnitude of the true mathematical quotient of n and d.

+    File Name:          11.6.1-1.js
+    ECMA Section:       11.6.1 The addition operator ( + )
+    Description:
+
+    The addition operator either performs string concatenation or numeric
+    addition.
+
+    The production AdditiveExpression : AdditiveExpression + MultiplicativeExpression
+    is evaluated as follows:
+
+    1.  Evaluate AdditiveExpression.
+    2.  Call GetValue(Result(1)).
+    3.  Evaluate MultiplicativeExpression.
+    4.  Call GetValue(Result(3)).
+    5.  Call ToPrimitive(Result(2)).
+    6.  Call ToPrimitive(Result(4)).
+    7.  If Type(Result(5)) is String or Type(Result(6)) is String, go to step 12.
+        (Note that this step differs from step 3 in the algorithm for comparison
+        for the relational operators in using or instead of and.)
+    8.  Call ToNumber(Result(5)).
+    9.  Call ToNumber(Result(6)).
+    10. Apply the addition operation to Result(8) and Result(9). See the discussion below (11.6.3).
+    11. Return Result(10).
+    12. Call ToString(Result(5)).
+    13. Call ToString(Result(6)).
+    14. Concatenate Result(12) followed by Result(13).
+    15. Return Result(14).
+
+    Note that no hint is provided in the calls to ToPrimitive in steps 5 and 6.
+    All native ECMAScript objects except Date objects handle the absence of a
+    hint as if the hint Number were given; Date objects handle the absence of a
+    hint as if the hint String were given. Host objects may handle the absence
+    of a hint in some other manner.
+
+    This test does not cover cases where the Additive or Mulplicative expression
+    ToPrimitive is string.

+    File Name:          11.6.1-2.js
+    ECMA Section:       11.6.1 The addition operator ( + )
+    Description:
+
+    The addition operator either performs string concatenation or numeric
+    addition.
+
+    The production AdditiveExpression : AdditiveExpression + MultiplicativeExpression
+    is evaluated as follows:
+
+    1.  Evaluate AdditiveExpression.
+    2.  Call GetValue(Result(1)).
+    3.  Evaluate MultiplicativeExpression.
+    4.  Call GetValue(Result(3)).
+    5.  Call ToPrimitive(Result(2)).
+    6.  Call ToPrimitive(Result(4)).
+    7.  If Type(Result(5)) is String or Type(Result(6)) is String, go to step 12.
+        (Note that this step differs from step 3 in the algorithm for comparison
+        for the relational operators in using or instead of and.)
+    8.  Call ToNumber(Result(5)).
+    9.  Call ToNumber(Result(6)).
+    10. Apply the addition operation to Result(8) and Result(9). See the discussion below (11.6.3).
+    11. Return Result(10).
+    12. Call ToString(Result(5)).
+    13. Call ToString(Result(6)).
+    14. Concatenate Result(12) followed by Result(13).
+    15. Return Result(14).
+
+    Note that no hint is provided in the calls to ToPrimitive in steps 5 and 6.
+    All native ECMAScript objects except Date objects handle the absence of a
+    hint as if the hint Number were given; Date objects handle the absence of a
+    hint as if the hint String were given. Host objects may handle the absence
+    of a hint in some other manner.
+
+    This test does only covers cases where the Additive or Mulplicative expression
+    ToPrimitive is a string.

+    ECMA Section:       11.6.1 The addition operator ( + )
+    Description:
+
+    The addition operator either performs string concatenation or numeric
+    addition.
+
+    The production AdditiveExpression : AdditiveExpression + MultiplicativeExpression
+    is evaluated as follows:
+
+    1.  Evaluate AdditiveExpression.
+    2.  Call GetValue(Result(1)).
+    3.  Evaluate MultiplicativeExpression.
+    4.  Call GetValue(Result(3)).
+    5.  Call ToPrimitive(Result(2)).
+    6.  Call ToPrimitive(Result(4)).
+    7.  If Type(Result(5)) is String or Type(Result(6)) is String, go to step 12.
+        (Note that this step differs from step 3 in the algorithm for comparison
+        for the relational operators in using or instead of and.)
+    8.  Call ToNumber(Result(5)).
+    9.  Call ToNumber(Result(6)).
+    10. Apply the addition operation to Result(8) and Result(9). See the discussion below (11.6.3).
+    11. Return Result(10).
+    12. Call ToString(Result(5)).
+    13. Call ToString(Result(6)).
+    14. Concatenate Result(12) followed by Result(13).
+    15. Return Result(14).
+
+    Note that no hint is provided in the calls to ToPrimitive in steps 5 and 6.
+    All native ECMAScript objects except Date objects handle the absence of a
+    hint as if the hint Number were given; Date objects handle the absence of a
+    hint as if the hint String were given. Host objects may handle the absence
+    of a hint in some other manner.
+
+    This test does only covers cases where the Additive or Mulplicative expression
+    is a Date.

+    File Name:          11.6.3.js
+    ECMA Section:       11.6.3 Applying the additive operators
+                        (+, -) to numbers
+    Description:
+    The + operator performs addition when applied to two operands of numeric
+    type, producing the sum of the operands. The - operator performs
+    subtraction, producing the difference of two numeric operands.
+
+    Addition is a commutative operation, but not always associative.
+
+    The result of an addition is determined using the rules of IEEE 754
+    double-precision arithmetic:
+
+      If either operand is NaN, the result is NaN.
+      The sum of two infinities of opposite sign is NaN.
+      The sum of two infinities of the same sign is the infinity of that sign.
+      The sum of an infinity and a finite value is equal to the infinite operand.
+      The sum of two negative zeros is 0. The sum of two positive zeros, or of
+        two zeros of opposite sign, is +0.
+      The sum of a zero and a nonzero finite value is equal to the nonzero
+        operand.
+      The sum of two nonzero finite values of the same magnitude and opposite
+        sign is +0.
+      In the remaining cases, where neither an infinity, nor a zero, nor NaN is
+        involved, and the operands have the same sign or have different
+        magnitudes, the sum is computed and rounded to the nearest
+        representable value using IEEE 754 round-to-nearest mode. If the
+        magnitude is too large to represent, the operation overflows and
+        the result is then an infinity of appropriate sign. The ECMAScript
+        language requires support of gradual underflow as defined by IEEE 754.

+    File Name:          11.7.3.js
+    ECMA Section:       11.7.3  The unsigned right shift operator ( >>> )
+    Description:
+    11.7.3 The unsigned right shift operator ( >>> )
+    Performs a zero-filling bitwise right shift operation on the left argument
+    by the amount specified by the right argument.
+
+    The production ShiftExpression : ShiftExpression >>> AdditiveExpression is
+    evaluated as follows:
+
+    1.  Evaluate ShiftExpression.
+    2.  Call GetValue(Result(1)).
+    3.  Evaluate AdditiveExpression.
+    4.  Call GetValue(Result(3)).
+    5.  Call ToUint32(Result(2)).
+    6.  Call ToUint32(Result(4)).
+    7.  Mask out all but the least significant 5 bits of Result(6), that is,
+        compute Result(6) & 0x1F.
+    8.  Perform zero-filling right shift of Result(5) by Result(7) bits.
+        Vacated bits are filled with zero. The result is an unsigned 32 bit
+        integer.
+    9.  Return Result(8).

+                        Function(p1, p2, ..., pn, body )
+
+    Description:
+    When the Function function is called with some arguments p1, p2, . . . , pn,
+    body (where n might be 0, that is, there are no "p" arguments, and where body
+    might also not be provided), the following steps are taken:
+
+    1.  Create and return a new Function object exactly if the function constructor
+    had been called with the same arguments (15.3.2.1).

+    File Name:          15.3.5-1.js
+    ECMA Section:       15.3.5 Properties of Function Instances
+                        new Function(p1, p2, ..., pn, body )
+
+    Description:
+
+    15.3.5.1 length
+
+    The value of the length property is usually an integer that indicates
+    the "typical" number of arguments expected by the function. However,
+    the language permits the function to be invoked with some other number
+    of arguments. The behavior of a function when invoked on a number of
+    arguments other than the number specified by its length property depends
+    on the function.
+
+    15.3.5.2 prototype
+    The value of the prototype property is used to initialize the internal [[
+    Prototype]] property of a newly created object before the Function object
+    is invoked as a constructor for that newly created object.
+
+    15.3.5.3 arguments
+
+    The value of the arguments property is normally null if there is no
+    outstanding invocation of the function in progress (that is, the function has been called
+    but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its
+    arguments property is "dynamically bound" to a newly created object that contains the
+    arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this
+    property is discouraged; it is provided principally for compatibility with existing old code.

+    File Name:          15.3.5-1.js
+    ECMA Section:       15.3.5 Properties of Function Instances
+                        new Function(p1, p2, ..., pn, body )
+
+    Description:
+
+    15.3.5.1 length
+
+    The value of the length property is usually an integer that indicates
+    the "typical" number of arguments expected by the function. However,
+    the language permits the function to be invoked with some other number
+    of arguments. The behavior of a function when invoked on a number of
+    arguments other than the number specified by its length property depends
+    on the function.
+
+    15.3.5.2 prototype
+    The value of the prototype property is used to initialize the internal [[
+    Prototype]] property of a newly created object before the Function object
+    is invoked as a constructor for that newly created object.
+
+    15.3.5.3 arguments
+
+    The value of the arguments property is normally null if there is no
+    outstanding invocation of the function in progress (that is, the function has been called
+    but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its
+    arguments property is "dynamically bound" to a newly created object that contains the
+    arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this
+    property is discouraged; it is provided principally for compatibility with existing old code.

+    File Name:          15.1.2.2-1.js
+    ECMA Section:       15.1.2.2 Function properties of the global object
+                        parseInt( string, radix )
+
+    Description:
+
+    The parseInt function produces an integer value dictated by intepretation
+    of the contents of the string argument according to the specified radix.
+
+    When the parseInt function is called, the following steps are taken:
+
+   1.   Call ToString(string).
+   2.   Compute a substring of Result(1) consisting of the leftmost character
+        that is not a StrWhiteSpaceChar and all characters to the right of
+        that character. (In other words, remove leading whitespace.)
+   3.   Let sign be 1.
+   4.   If Result(2) is not empty and the first character of Result(2) is a
+        minus sign -, let sign be -1.
+   5.   If Result(2) is not empty and the first character of Result(2) is a
+        plus sign + or a minus sign -, then Result(5) is the substring of
+        Result(2) produced by removing the first character; otherwise, Result(5)
+        is Result(2).
+   6.   If the radix argument is not supplied, go to step 12.
+   7.   Call ToInt32(radix).
+   8.   If Result(7) is zero, go to step 12; otherwise, if Result(7) < 2 or
+        Result(7) > 36, return NaN.
+   9.   Let R be Result(7).
+  10.   If R = 16 and the length of Result(5) is at least 2 and the first two
+        characters of Result(5) are either "0x" or "0X", let S be the substring
+        of Result(5) consisting of all but the first two characters; otherwise,
+        let S be Result(5).
+  11.   Go to step 22.
+  12.   If Result(5) is empty or the first character of Result(5) is not 0,
+        go to step 20.
+  13.   If the length of Result(5) is at least 2 and the second character of
+        Result(5) is x or X, go to step 17.
+  14.   Let R be 8.
+  15.   Let S be Result(5).
+  16.   Go to step 22.
+  17.   Let R be 16.
+  18.   Let S be the substring of Result(5) consisting of all but the first
+        two characters.
+  19.   Go to step 22.
+  20.   Let R be 10.
+  21.   Let S be Result(5).
+  22.   If S contains any character that is not a radix-R digit, then let Z be
+        the substring of S consisting of all characters to the left of the
+        leftmost such character; otherwise, let Z be S.
+  23.   If Z is empty, return NaN.
+  24.   Compute the mathematical integer value that is represented by Z in
+        radix-R notation. (But if R is 10 and Z contains more than 20
+        significant digits, every digit after the 20th may be replaced by a 0
+        digit, at the option of the implementation; and if R is not 2, 4, 8,
+        10, 16, or 32, then Result(24) may be an implementation-dependent
+        approximation to the mathematical integer value that is represented
+        by Z in radix-R notation.)
+  25.   Compute the number value for Result(24).
+  26.   Return sign Result(25).
+
+    Note that parseInt may interpret only a leading portion of the string as
+    an integer value; it ignores any characters that cannot be interpreted as
+    part of the notation of an integer, and no indication is given that any
+    such characters were ignored.

+    File Name:          15.1.2.3.js
+    ECMA Section:       15.1.2.3 Function properties of the global object:
+                        parseFloat( string )
+
+    Description:        The parseFloat function produces a number value dictated
+                        by the interpretation of the contents of the string
+                        argument defined as a decimal literal.
+
+                        When the parseFloat function is called, the following
+                        steps are taken:
+
+                        1.  Call ToString( string ).
+                        2.  Remove leading whitespace Result(1).
+                        3.  If neither Result(2) nor any prefix of Result(2)
+                            satisfies the syntax of a StrDecimalLiteral,
+                            return NaN.
+                        4.  Compute the longest prefix of Result(2) which might
+                            be Resusult(2) itself, that satisfies the syntax of
+                            a StrDecimalLiteral
+                        5.  Return the number value for the MV of Result(4).
+
+                        Note that parseFloate may interpret only a leading
+                        portion of the string as a number value; it ignores any
+                        characters that cannot be interpreted as part of the
+                        notation of a decimal literal, and no indication is given
+                        that such characters were ignored.
+
+                        StrDecimalLiteral::
+                        Infinity
+                        DecimalDigits.DecimalDigits opt ExponentPart opt
+                        .DecimalDigits ExponentPart opt

+    File Name:          15.1.2.3-2.js
+    ECMA Section:       15.1.2.3 Function properties of the global object:
+                        parseFloat( string )
+
+    Description:        The parseFloat function produces a number value dictated
+                        by the interpretation of the contents of the string
+                        argument defined as a decimal literal.
+
+                        When the parseFloat function is called, the following
+                        steps are taken:
+
+                        1.  Call ToString( string ).
+                        2.  Remove leading whitespace Result(1).
+                        3.  If neither Result(2) nor any prefix of Result(2)
+                            satisfies the syntax of a StrDecimalLiteral,
+                            return NaN.
+                        4.  Compute the longest prefix of Result(2) which might
+                            be Resusult(2) itself, that satisfies the syntax of
+                            a StrDecimalLiteral
+                        5.  Return the number value for the MV of Result(4).
+
+                        Note that parseFloate may interpret only a leading
+                        portion of the string as a number value; it ignores any
+                        characters that cannot be interpreted as part of the
+                        notation of a decimal literal, and no indication is given
+                        that such characters were ignored.
+
+                        StrDecimalLiteral::
+                        Infinity
+                        DecimalDigits.DecimalDigits opt ExponentPart opt
+                        .DecimalDigits ExponentPart opt

+    File Name:          15.1.2.4.js
+    ECMA Section:       15.1.2.4  Function properties of the global object
+                        escape( string )
+
+    Description:
+    The escape function computes a new version of a string value in which
+    certain characters have been replaced by a hexadecimal escape sequence.
+    The result thus contains no special characters that might have special
+    meaning within a URL.
+
+    For characters whose Unicode encoding is 0xFF or less, a two-digit
+    escape sequence of the form %xx is used in accordance with RFC1738.
+    For characters whose Unicode encoding is greater than 0xFF, a four-
+    digit escape sequence of the form %uxxxx is used.
+
+    When the escape function is called with one argument string, the
+    following steps are taken:
+
+    1.  Call ToString(string).
+    2.  Compute the number of characters in Result(1).
+    3.  Let R be the empty string.
+    4.  Let k be 0.
+    5.  If k equals Result(2), return R.
+    6.  Get the character at position k within Result(1).
+    7.  If Result(6) is one of the 69 nonblank ASCII characters
+        ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz
+        0123456789 @*_+-./, go to step 14.
+    8.  Compute the 16-bit unsigned integer that is the Unicode character
+        encoding of Result(6).
+    9.  If Result(8), is less than 256, go to step 12.
+   10.  Let S be a string containing six characters "%uwxyz" where wxyz are
+        four hexadecimal digits encoding the value of Result(8).
+   11.  Go to step 15.
+   12.  Let S be a string containing three characters "%xy" where xy are two
+        hexadecimal digits encoding the value of Result(8).
+   13.  Go to step 15.
+   14.  Let S be a string containing the single character Result(6).
+   15.  Let R be a new string value computed by concatenating the previous value
+        of R and S.
+   16.  Increase k by 1.
+   17.  Go to step 5.

+    File Name:          15.1.2.5-3.js
+    ECMA Section:       15.1.2.5  Function properties of the global object
+                        unescape( string )
+
+    Description:
+    This tests the cases where one of the four characters following "%u" is
+    not a hexidecimal character, or one of the two characters following "%"
+    or "%u" is not a hexidecimal character.
+
+    The unescape function computes a new version of a string value in which
+    each escape sequences of the sort that might be introduced by the escape
+    function is replaced with the character that it represents.
+
+    When the unescape function is called with one argument string, the
+    following steps are taken:
+
+    1.  Call ToString(string).
+    2.  Compute the number of characters in Result(1).
+    3.  Let R be the empty string.
+    4.  Let k be 0.
+    5.  If k equals Result(2), return R.
+    6.  Let c be the character at position k within Result(1).
+    7.  If c is not %, go to step 18.
+    8.  If k is greater than Result(2)-6, go to step 14.
+    9.  If the character at position k+1 within result(1) is not u, go to step
+        14.
+    10. If the four characters at positions k+2, k+3, k+4, and k+5 within
+        Result(1) are not all hexadecimal digits, go to step 14.
+    11. Let c be the character whose Unicode encoding is the integer represented
+        by the four hexadecimal digits at positions k+2, k+3, k+4, and k+5
+        within Result(1).
+    12. Increase k by 5.
+    13. Go to step 18.
+    14. If k is greater than Result(2)-3, go to step 18.
+    15. If the two characters at positions k+1 and k+2 within Result(1) are not
+        both hexadecimal digits, go to step 18.
+    16. Let c be the character whose Unicode encoding is the integer represented
+        by two zeroes plus the two hexadecimal digits at positions k+1 and k+2
+        within Result(1).
+    17. Increase k by 2.
+    18. Let R be a new string value computed by concatenating the previous value
+        of R and c.
+    19. Increase k by 1.
+    20. Go to step 5.

+    This is a regression test for

+
+    Waldemar's comments:
+
+    A numeric literal that starts with either '08' or '09' is interpreted as a
+    decimal literal; it should be an error instead.  (Strictly speaking, according
+    to ECMA v1 such literals should be interpreted as two integers -- a zero
+    followed by a decimal number whose first digit is 8 or 9, but this is a bug in
+    ECMA that will be fixed in v2.  In any case, there is no place in the grammar
+    where two consecutive numbers would be legal.)

+                        close to the argument. then the result is the number value
+                        that is closer to Infinity.  if the argument is an integer,
+                        return the argument.
+                        special cases:
+                            - if x is NaN       return NaN
+                            - if x = +0         return +0

+                            - if -0.5 <= x < 0  return -0
+                        example:
+                            Math.round( 3.5 ) == 4
+                            Math.round( -3.5 ) == 3
+                        also:

+    Description:
+    If the radix is the number 10 or not supplied, then this number value is

+    is returned.
+
+    If the radix is supplied and is an integer from 2 to 36, but not 10, the
+    result is a string, the choice of which is implementation dependent.
+
+    The toString function is not generic; it generates a runtime error if its
+    this value is not a Number object. Therefore it cannot be transferred to
+    other kinds of objects for use as a method.

+
+    Description:
+
+    The Number prototype object is itself a Number object (its [[Class]] is
+    "Number") whose value is +0.
+
+    The value of the internal [[Prototype]] property of the Number prototype
+    object is the Object prototype object (15.2.3.1).
+
+    In following descriptions of functions that are properties of the Number
+    prototype object, the phrase "this Number object" refers to the object
+    that is the this value for the invocation of the function; it is an error
+    if this does not refer to an object for which the value of the internal
+    [[Class]] property is "Number". Also, the phrase "this number value" refers
+    to the number value represented by this Number object, that is, the value
+    of the internal [[Value]] property of this Number object.

+    ECMA Section:       15.2.2.1 The Object Constructor:  new Object( value )
+
+    1.If the type of the value is not Object, go to step 4.
+    2.If the value is a native ECMAScript object, do not create a new object; simply return value.
+    3.If the value is a host object, then actions are taken and a result is returned in an
+      implementation-dependent manner that may depend on the host object.
+    4.If the type of the value is String, return ToObject(value).
+    5.If the type of the value is Boolean, return ToObject(value).
+    6.If the type of the value is Number, return ToObject(value).
+    7.(The type of the value must be Null or Undefined.) Create a new native ECMAScript object.
+      The [[Prototype]] property of the newly constructed object is set to the Object prototype object.
+      The [[Class]] property of the newly constructed object is set to "Object".
+      The newly constructed object has no [[Value]] property.
+      Return the newly created native object.
+
+    Description:        This does not test cases where the object is a host object.

+                        should be returned.

+                        This only covers native objects.

+/**
+    File Name:          6-1.js
+    ECMA Section:       Source Text
+    Description:
+
+    ECMAScript source text is represented as a sequence of characters
+    representable using the Unicode version 2.0 character encoding.
+
+    SourceCharacter ::
+    any Unicode character
+
+    However, it is possible to represent every ECMAScript program using
+    only ASCII characters (which are equivalent to the first 128 Unicode
+    characters). Non-ASCII Unicode characters may appear only within comments
+    and string literals. In string literals, any Unicode character may also be
+    expressed as a Unicode escape sequence consisting of six ASCII characters,
+    namely \u plus four hexadecimal digits. Within a comment, such an escape
+    sequence is effectively ignored as part of the comment. Within a string
+    literal, the Unicode escape sequence contributes one character to the string
+    value of the literal.
+
+    Note that ECMAScript differs from the Java programming language in the
+    behavior of Unicode escape sequences. In a Java program, if the Unicode escape
+    sequence \u000A, for example, occurs within a single-line comment, it is
+    interpreted as a line terminator (Unicode character 000A is line feed) and
+    therefore the next character is not part of the comment. Similarly, if the
+    Unicode escape sequence \u000A occurs within a string literal in a Java
+    program, it is likewise interpreted as a line terminator, which is not
+    allowed within a string literal-one must write \n instead of \u000A to
+    cause a line feed to be part of the string value of a string literal. In
+    an ECMAScript program, a Unicode escape sequence occurring within a comment
+    is never interpreted and therefore cannot contribute to termination of the
+    comment. Similarly, a Unicode escape sequence occurring within a string literal
+    in an ECMAScript program always contributes a character to the string value of
+    the literal and is never interpreted as a line terminator or as a quote mark
+    that might terminate the string literal.

+    Note that ECMAScript differs from the Java programming language in the
+    behavior of Unicode escape sequences. In a Java program, if the Unicode escape
+    sequence \u000A, for example, occurs within a single-line comment, it is
+    interpreted as a line terminator (Unicode character 000A is line feed) and
+    therefore the next character is not part of the comment. Similarly, if the
+    Unicode escape sequence \u000A occurs within a string literal in a Java
+    program, it is likewise interpreted as a line terminator, which is not
+    allowed within a string literal-one must write \n instead of \u000A to
+    cause a line feed to be part of the string value of a string literal. In
+    an ECMAScript program, a Unicode escape sequence occurring within a comment
+    is never interpreted and therefore cannot contribute to termination of the
+    comment. Similarly, a Unicode escape sequence occurring within a string literal
+    in an ECMAScript program always contributes a character to the string value of
+    the literal and is never interpreted as a line terminator or as a quote mark
+    that might terminate the string literal.

+    File Name:          12.10-1.js
+    ECMA Section:       12.10 The with statement
+    Description:
+    WithStatement :
+    with ( Expression ) Statement
+
+    The with statement adds a computed object to the front of the scope chain
+    of the current execution context, then executes a statement with this
+    augmented scope chain, then restores the scope chain.
+
+    Semantics
+
+    The production WithStatement : with ( Expression ) Statement is evaluated
+    as follows:
+    1.  Evaluate Expression.
+    2.  Call GetValue(Result(1)).
+    3.  Call ToObject(Result(2)).
+    4.  Add Result(3) to the front of the scope chain.
+    5.  Evaluate Statement using the augmented scope chain from step 4.
+    6.  Remove Result(3) from the front of the scope chain.
+    7.  Return Result(5).
+
+    Discussion
+    Note that no matter how control leaves the embedded Statement, whether
+    normally or by some form of abrupt completion, the scope chain is always
+    restored to its former state.

+    Description:
+    The production IterationStatement : for ( LeftHandSideExpression in Expression )
+    Statement is evaluated as follows:
+
+    1.  Evaluate the Expression.
+    2.  Call GetValue(Result(1)).
+    3.  Call ToObject(Result(2)).
+    4.  Let C be "normal completion".
+    5.  Get the name of the next property of Result(3) that doesn't have the
+        DontEnum attribute. If there is no such property, go to step 14.
+    6.  Evaluate the LeftHandSideExpression (it may be evaluated repeatedly).
+    7.  Call PutValue(Result(6), Result(5)).  PutValue( V, W ):
+        1.  If Type(V) is not Reference, generate a runtime error.

+			a constructor, it performs a type conversion.
+			- String(value) returns a string value (not a String
+			object) computed by ToString(value)
+			- String() returns the empty string ""

+        			- The internal [[Class]] property of the object is "String"
+        			- The value of the object is ToString(value).
+        			- If no value is specified, its value is the empty string.

+    Description:        Return a string value containing as many characters
+                        as the number of arguments.  Each argument specifies
+                        one character of the resulting string, with the first

+                        from left to right.  An argument is converted to a
+                        character by applying the operation ToUint16 and
+                        regarding the resulting 16bit integeras the Unicode

+    Description:        Return a string value containing as many characters
+                        as the number of arguments.  Each argument specifies
+                        one character of the resulting string, with the first
+                        argument specifying the first character, and so on,
+                        from left to right.  An argument is converted to a
+                        character by applying the operation ToUint16 and
+                        regarding the resulting 16bit integeras the Unicode
+                        encoding of a character.  If no arguments are supplied,
+                        the result is the empty string.
+
+                        This tests String.fromCharCode with multiple arguments.

+    File Name:          15.5.4.10-1.js
+    ECMA Section:       15.5.4.10 String.prototype.substring( start, end )
+    Description:
+
+    15.5.4.10 String.prototype.substring(start, end)
+
+    Returns a substring of the result of converting this object to a string,
+    starting from character position start and running to character position
+    end of the string. The result is a string value, not a String object.
+
+    If either argument is NaN or negative, it is replaced with zero; if either
+    argument is larger than the length of the string, it is replaced with the
+    length of the string.
+
+    If start is larger than end, they are swapped.
+
+    When the substring method is called with two arguments start and end, the
+    following steps are taken:
+
+    1.  Call ToString, giving it the this value as its argument.
+    2.  Call ToInteger(start).
+    3.  Call ToInteger (end).
+    4.  Compute the number of characters in Result(1).
+    5.  Compute min(max(Result(2), 0), Result(4)).
+    6.  Compute min(max(Result(3), 0), Result(4)).
+    7.  Compute min(Result(5), Result(6)).
+    8.  Compute max(Result(5), Result(6)).
+    9.  Return a string whose length is the difference between Result(8) and
+        Result(7), containing characters from Result(1), namely the characters
+        with indices Result(7) through Result(8)1, in ascending order.
+
+    Note that the substring function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+    File Name:          15.5.4.11-1.js
+    ECMA Section:       15.5.4.11 String.prototype.toLowerCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toLowerCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+   File Name:          15.5.4.11-2.js
+   ECMA Section:       15.5.4.11 String.prototype.toLowerCase()
+   Description:
+
+   Returns a string equal in length to the length of the result of converting
+   this object to a string. The result is a string value, not a String object.
+
+   Every character of the result is equal to the corresponding character of the
+   string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+   case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+   mapping shall be used, which does not depend on implementation or locale.)
+
+   Note that the toLowerCase function is intentionally generic; it does not require
+   that its this value be a String object. Therefore it can be transferred to other
+   kinds of objects for use as a method.

+    Safari Changes:  This test differs from the mozilla tests in two significant
+    ways.
+        First, the lower case range for Georgian letters in this file is the
+    correct range according to the Unicode 5.0 standard, as opposed to the 
+    Georgian caseless range that mozilla uses.
+        Secondly this test uses an array for expected results with two entries,
+    instead of a single expected result. This allows us to accept Unicode 4.0 or
+    Unicode 5.0 results as correct, as opposed to the mozilla test, which assumes
+    Unicode 5.0.  This allows Safari to pass this test on OS' with different
+    Unicode standards implemented (e.g. Tiger and XP)

+    File Name:          15.5.4.11-2.js
+    ECMA Section:       15.5.4.11 String.prototype.toLowerCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toLowerCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+    File Name:          15.5.4.11-2.js
+    ECMA Section:       15.5.4.11 String.prototype.toLowerCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toLowerCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+    File Name:          15.5.4.11-6.js
+    ECMA Section:       15.5.4.11 String.prototype.toLowerCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toLowerCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+    File Name:          15.5.4.12-1.js
+    ECMA Section:       15.5.4.12 String.prototype.toUpperCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toUpperCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+    File Name:          15.5.4.12-2.js
+    ECMA Section:       15.5.4.12 String.prototype.toUpperCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toUpperCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+    File Name:          15.5.4.12-3.js
+    ECMA Section:       15.5.4.12 String.prototype.toUpperCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toUpperCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+    File Name:          15.5.4.12-1.js
+    ECMA Section:       15.5.4.12 String.prototype.toUpperCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toUpperCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+    File Name:          15.5.4.12-1.js
+    ECMA Section:       15.5.4.12 String.prototype.toUpperCase()
+    Description:
+
+    Returns a string equal in length to the length of the result of converting
+    this object to a string. The result is a string value, not a String object.
+
+    Every character of the result is equal to the corresponding character of the
+    string, unless that character has a Unicode 2.0 uppercase equivalent, in which
+    case the uppercase equivalent is used instead. (The canonical Unicode 2.0 case
+    mapping shall be used, which does not depend on implementation or locale.)
+
+    Note that the toUpperCase function is intentionally generic; it does not require
+    that its this value be a String object. Therefore it can be transferred to other
+    kinds of objects for use as a method.

+                        pos in the string.  If there is no character at that
+                        string, the result is the empty string.  The result is
+                        a string value, not a String object.
+
+                        When the charAt method is called with one argument,
+                        pos, the following steps are taken:
+                        1. Call ToString, with this value as its argument
+                        2. Call ToInteger pos
+
+                        In this test, this is a String, pos is an integer, and
+                        all pos are in range.

+                        string, the result is the empty string.  The result is
+                        a string value, not a String object.

+                        When the charAt method is called with one argument,
+                        pos, the following steps are taken:
+                        1. Call ToString, with this value as its argument
+                        2. Call ToInteger pos
+                        3. Compute the number of characters  in Result(1)
+                        4. If Result(2) is less than 0 is or not less than
+                           Result(3), return the empty string
+                        5. Return a string of length 1 containing one character
+                           from result (1), the character at position Result(2).
+
+                        Note that the charAt function is intentionally generic;
+                        it does not require that its this value be a String

+                        of objects for use as a method.
+
+                        This tests assiging charAt to a user-defined function.

+    File Name:          15.5.4.4-4.js
+    ECMA Section:       15.5.4.4 String.prototype.charAt(pos)
+    Description:        Returns a string containing the character at position
+                        pos in the string.  If there is no character at that
+                        string, the result is the empty string.  The result is
+                        a string value, not a String object.
+
+                        When the charAt method is called with one argument,
+                        pos, the following steps are taken:
+                        1. Call ToString, with this value as its argument
+                        2. Call ToInteger pos
+                        3. Compute the number of characters  in Result(1)
+                        4. If Result(2) is less than 0 is or not less than
+                           Result(3), return the empty string
+                        5. Return a string of length 1 containing one character
+                           from result (1), the character at position Result(2).
+
+                        Note that the charAt function is intentionally generic;
+                        it does not require that its this value be a String
+                        object.  Therefore it can be transferred to other kinds
+                        of objects for use as a method.
+
+                        This tests assiging charAt to primitive types..

+    File Name:          15.5.4.6-1.js
+    ECMA Section:       15.5.4.6 String.prototype.indexOf( searchString, pos)
+    Description:        If the given searchString appears as a substring of the
+                        result of converting this object to a string, at one or
+                        more positions that are at or to the right of the
+                        specified position, then the index of the leftmost such
+                        position is returned; otherwise -1 is returned.  If
+                        positionis undefined or not supplied, 0 is assumed, so
+                        as to search all of the string.
+
+                        When the indexOf method is called with two arguments,
+                        searchString and pos, the following steps are taken:
+
+                        1. Call ToString, giving it the this value as its
+                           argument.
+                        2. Call ToString(searchString).
+                        3. Call ToInteger(position). (If position is undefined
+                           or not supplied, this step produces the value 0).
+                        4. Compute the number of characters in Result(1).
+                        5. Compute min(max(Result(3), 0), Result(4)).
+                        6. Compute the number of characters in the string that
+                           is Result(2).
+                        7. Compute the smallest possible integer k not smaller
+                           than Result(5) such that k+Result(6) is not greater
+                           than Result(4), and for all nonnegative integers j
+                           less than Result(6), the character at position k+j
+                           of Result(1) is the same as the character at position
+                           j of Result(2); but if there is no such integer k,
+                           then compute the value -1.
+                        8. Return Result(7).
+
+                        Note that the indexOf function is intentionally generic;
+                        it does not require that its this value be a String object.
+                        Therefore it can be transferred to other kinds of objects
+                        for use as a method.

+    File Name:          15.5.4.7-1.js
+    ECMA Section:       15.5.4.7 String.prototype.lastIndexOf( searchString, pos)
+    Description:
+
+    If the given searchString appears as a substring of the result of
+    converting this object to a string, at one or more positions that are
+    at or to the left of the specified position, then the index of the
+    rightmost such position is returned; otherwise -1 is returned. If position
+    is undefined or not supplied, the length of this string value is assumed,
+    so as to search all of the string.
+
+    When the lastIndexOf method is called with two arguments searchString and
+    position, the following steps are taken:
+
+   1.Call ToString, giving it the this value as its argument.
+   2.Call ToString(searchString).
+   3.Call ToNumber(position). (If position is undefined or not supplied, this step produces the value NaN).
+   4.If Result(3) is NaN, use +; otherwise, call ToInteger(Result(3)).
+   5.Compute the number of characters in Result(1).
+   6.Compute min(max(Result(4), 0), Result(5)).
+   7.Compute the number of characters in the string that is Result(2).
+   8.Compute the largest possible integer k not larger than Result(6) such that k+Result(7) is not greater
+      than Result(5), and for all nonnegative integers j less than Result(7), the character at position k+j of
+      Result(1) is the same as the character at position j of Result(2); but if there is no such integer k, then
+      compute the value -1.
+
+   1.Return Result(8).
+
+    Note that the lastIndexOf function is intentionally generic; it does not require that its this value be a
+    String object. Therefore it can be transferred to other kinds of objects for use as a method.

+    File Name:          15.5.4.7-2.js
+    ECMA Section:       15.5.4.7 String.prototype.lastIndexOf( searchString, pos)
+    Description:
+
+    If the given searchString appears as a substring of the result of
+    converting this object to a string, at one or more positions that are
+    at or to the left of the specified position, then the index of the
+    rightmost such position is returned; otherwise -1 is returned. If position
+    is undefined or not supplied, the length of this string value is assumed,
+    so as to search all of the string.
+
+    When the lastIndexOf method is called with two arguments searchString and
+    position, the following steps are taken:
+
+   1.Call ToString, giving it the this value as its argument.
+   2.Call ToString(searchString).
+   3.Call ToNumber(position). (If position is undefined or not supplied, this step produces the value NaN).
+   4.If Result(3) is NaN, use +; otherwise, call ToInteger(Result(3)).
+   5.Compute the number of characters in Result(1).
+   6.Compute min(max(Result(4), 0), Result(5)).
+   7.Compute the number of characters in the string that is Result(2).
+   8.Compute the largest possible integer k not larger than Result(6) such that k+Result(7) is not greater
+      than Result(5), and for all nonnegative integers j less than Result(7), the character at position k+j of
+      Result(1) is the same as the character at position j of Result(2); but if there is no such integer k, then
+      compute the value -1.
+
+   1.Return Result(8).
+
+    Note that the lastIndexOf function is intentionally generic; it does not require that its this value be a
+    String object. Therefore it can be transferred to other kinds of objects for use as a method.

+    is undefined or not supplied, the length of this string value is assumed,
+    so as to search all of the string.
+
+    When the lastIndexOf method is called with two arguments searchString and
+    position, the following steps are taken:
+
+   1.Call ToString, giving it the this value as its argument.
+   2.Call ToString(searchString).
+   3.Call ToNumber(position). (If position is undefined or not supplied, this step produces the value NaN).
+   4.If Result(3) is NaN, use +; otherwise, call ToInteger(Result(3)).
+   5.Compute the number of characters in Result(1).
+   6.Compute min(max(Result(4), 0), Result(5)).
+   7.Compute the number of characters in the string that is Result(2).
+   8.Compute the largest possible integer k not larger than Result(6) such that k+Result(7) is not greater
+      than Result(5), and for all nonnegative integers j less than Result(7), the character at position k+j of
+      Result(1) is the same as the character at position j of Result(2); but if there is no such integer k, then
+      compute the value -1.
+
+   1.Return Result(8).
+
+    Note that the lastIndexOf function is intentionally generic; it does not require that its this value be a
+    String object. Therefore it can be transferred to other kinds of objects for use as a method.

+    ECMA Section:       15.5.4.8 String.prototype.split( separator )
+    Description:
+
+    Returns an Array object into which substrings of the result of converting
+    this object to a string have been stored. The substrings are determined by
+    searching from left to right for occurrences of the given separator; these
+    occurrences are not part of any substring in the returned array, but serve
+    to divide up this string value. The separator may be a string of any length.
+
+    As a special case, if the separator is the empty string, the string is split
+    up into individual characters; the length of the result array equals the
+    length of the string, and each substring contains one character.
+
+    If the separator is not supplied, then the result array contains just one
+    string, which is the string.

+    File Name:          15.5.4.8-2.js
+    ECMA Section:       15.5.4.8 String.prototype.split( separator )
+    Description:
+
+    Returns an Array object into which substrings of the result of converting
+    this object to a string have been stored. The substrings are determined by
+    searching from left to right for occurrences of the given separator; these
+    occurrences are not part of any substring in the returned array, but serve
+    to divide up this string value. The separator may be a string of any length.
+
+    As a special case, if the separator is the empty string, the string is split
+    up into individual characters; the length of the result array equals the
+    length of the string, and each substring contains one character.
+
+    If the separator is not supplied, then the result array contains just one
+    string, which is the string.
+
+    When the split method is called with one argument separator, the following steps are taken:
+
+   1.   Call ToString, giving it the this value as its argument.
+   2.   Create a new Array object of length 0 and call it A.
+   3.   If separator is not supplied, call the [[Put]] method of A with 0 and
+        Result(1) as arguments, and then return A.
+   4.   Call ToString(separator).
+   5.   Compute the number of characters in Result(1).
+   6.   Compute the number of characters in the string that is Result(4).
+   7.   Let p be 0.
+   8.   If Result(6) is zero (the separator string is empty), go to step 17.
+   9.   Compute the smallest possible integer k not smaller than p such that
+        k+Result(6) is not greater than Result(5), and for all nonnegative
+        integers j less than Result(6), the character at position k+j of
+        Result(1) is the same as the character at position j of Result(2);
+        but if there is no such integer k, then go to step 14.
+  10.   Compute a string value equal to the substring of Result(1), consisting
+        of the characters at positions p through k1, inclusive.
+  11.   Call the [[Put]] method of A with A.length and Result(10) as arguments.
+  12.   Let p be k+Result(6).
+  13.   Go to step 9.
+  14.   Compute a string value equal to the substring of Result(1), consisting
+        of the characters from position p to the end of Result(1).
+  15.   Call the [[Put]] method of A with A.length and Result(14) as arguments.
+  16.   Return A.
+  17.   If p equals Result(5), return A.
+  18.   Compute a string value equal to the substring of Result(1), consisting of
+        the single character at position p.
+  19.   Call the [[Put]] method of A with A.length and Result(18) as arguments.
+  20.   Increase p by 1.
+  21.   Go to step 17.
+
+Note that the split function is intentionally generic; it does not require that its this value be a String
+object. Therefore it can be transferred to other kinds of objects for use as a method.

+    As a special case, if the separator is the empty string, the string is split
+    up into individual characters; the length of the result array equals the
+    length of the string, and each substring contains one character.
+
+    If the separator is not supplied, then the result array contains just one
+    string, which is the string.
+
+    When the split method is called with one argument separator, the following steps are taken:
+
+   1.   Call ToString, giving it the this value as its argument.
+   2.   Create a new Array object of length 0 and call it A.
+   3.   If separator is not supplied, call the [[Put]] method of A with 0 and
+        Result(1) as arguments, and then return A.
+   4.   Call ToString(separator).
+   5.   Compute the number of characters in Result(1).
+   6.   Compute the number of characters in the string that is Result(4).
+   7.   Let p be 0.
+   8.   If Result(6) is zero (the separator string is empty), go to step 17.
+   9.   Compute the smallest possible integer k not smaller than p such that
+        k+Result(6) is not greater than Result(5), and for all nonnegative
+        integers j less than Result(6), the character at position k+j of
+        Result(1) is the same as the character at position j of Result(2);
+        but if there is no such integer k, then go to step 14.
+  10.   Compute a string value equal to the substring of Result(1), consisting
+        of the characters at positions p through k1, inclusive.
+  11.   Call the [[Put]] method of A with A.length and Result(10) as arguments.
+  12.   Let p be k+Result(6).
+  13.   Go to step 9.
+  14.   Compute a string value equal to the substring of Result(1), consisting
+        of the characters from position p to the end of Result(1).
+  15.   Call the [[Put]] method of A with A.length and Result(14) as arguments.
+  16.   Return A.
+  17.   If p equals Result(5), return A.
+  18.   Compute a string value equal to the substring of Result(1), consisting of
+        the single character at position p.
+  19.   Call the [[Put]] method of A with A.length and Result(18) as arguments.
+  20.   Increase p by 1.
+  21.   Go to step 17.
+
+Note that the split function is intentionally generic; it does not require that its this value be a String
+object. Therefore it can be transferred to other kinds of objects for use as a method.

+    Description:
+
+    15.5.4.9 String.prototype.substring(start)
+
+    Returns a substring of the result of converting this object to a string,
+    starting from character position start and running to the end of the
+    string. The result is a string value, not a String object.
+
+    If the argument is NaN or negative, it is replaced with zero; if the
+    argument is larger than the length of the string, it is replaced with the
+    length of the string.
+
+    When the substring method is called with one argument start, the following
+    steps are taken:
+
+    1.Call ToString, giving it the this value as its argument.
+    2.Call ToInteger(start).
+    3.Compute the number of characters in Result(1).
+    4.Compute min(max(Result(2), 0), Result(3)).
+    5.Return a string whose length is the difference between Result(3) and Result(4),
+    containing characters from Result(1), namely the characters with indices Result(4)
+    through Result(3)1, in ascending order.

+    Description:        1.  Call ToNumber on the input argument
+                        2.  If Result(1) is NaN, return +0
+                        3.  If Result(1) is +0, -0, Infinity, or -Infinity,
+                            return Result(1).
+                        4.  Compute sign(Result(1)) * floor(abs(Result(1))).
+                        5.  Return Result(4).
+
+                        To test ToInteger, this test uses new Date(value),
+                        15.9.3.7.  The Date constructor sets the [[Value]]
+                        property of the new object to TimeClip(value), which
+                        uses the rules:
+
+                        TimeClip(time)
+                        1. If time is not finite, return NaN
+                        2. If abs(Result(1)) > 8.64e15, return NaN
+                        3. Return an implementation dependent choice of either
+                        ToInteger(Result(2)) or ToInteger(Result(2)) + (+0)
+                        (Adding a positive 0 converts -0 to +0).
+
+                        This tests ToInteger for values -8.64e15 > value > 8.64e15,
+                        not including -0 and +0.
+
+                        For additional special cases (0, +0, Infinity, -Infinity,
+                        and NaN, see 9.4-2.js).  For value is String, see 9.4-3.js.

+
+                        this test uses << 0 to convert the argument to a 32bit
+                        integer.
+
+                        The operator ToInt32 converts its argument to one of 2^32
+                        integer values in the range -2^31 through 2^31 inclusive.
+                        This operator functions as follows:
+
+                        1 call ToNumber on argument
+                        2 if result is NaN, 0, -0, return 0
+                        3 compute (sign (result(1)) * floor(abs(result 1)))
+                        4 compute result(3) modulo 2^32:
+                        5 if result(4) is greater than or equal to 2^31, return
+                          result(5)-2^32.  otherwise, return result(5)
+
+                        special cases:
+                            -0          returns 0
+                            Infinity    returns 0
+                            -Infinity   returns 0
+                            ToInt32(ToUint32(x)) == ToInt32(x) for all values of x
+                            Numbers greater than 2^31 (see step 5 above)

+    Description:        rules for converting an argument to an unsigned
+                        32 bit integer
+
+                        this test uses >>> 0 to convert the argument to
+                        an unsigned 32bit integer.
+
+                        1 call ToNumber on argument
+                        2 if result is NaN, 0, -0, Infinity, -Infinity
+                            return 0
+                        3 compute (sign (result(1)) * floor(abs(result 1)))
+                        4 compute result(3) modulo 2^32:
+                        5 return result(4)
+
+                        special cases:
+                            -0          returns 0
+                            Infinity    returns 0
+                            -Infinity   returns 0
+                            0           returns 0
+                            ToInt32(ToUint32(x)) == ToInt32(x) for all values of x

+    File Name:          8.4.js
+    ECMA Section:       The String type
+    Description:
+
+    The String type is the set of all finite ordered sequences of zero or more
+    Unicode characters. Each character is regarded as occupying a position
+    within the sequence. These positions are identified by nonnegative
+    integers. The leftmost character (if any) is at position 0, the next
+    character (if any) at position 1, and so on. The length of a string is the
+    number of distinct positions within it. The empty string has length zero
+    and therefore contains no characters.
