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. + + Author: christine@netscape.com + Date: 12 november 1997 +*/ + + var SECTION = "10.1.8-2"; + var VERSION = "ECMA_1"; + startTest(); + var TITLE = "Arguments Object"; + + writeHeaderToLog( SECTION + " "+ TITLE); + + var testcases = new Array(); + +// Tests for anonymous functions + + var GetCallee = new Function( "var c = arguments.callee; return c" ); + var GetArguments = new Function( "var a = arguments; return a" ); + var GetLength = new Function( "var l = arguments.length; return l" ); + + var ARG_STRING = "value of the argument property"; + + testcases[tc++] = new TestCase( SECTION, + "GetCallee()", + GetCallee, + GetCallee() ); + + var LIMIT = 100; + + for ( var i = 0, args = "" ; i < LIMIT; i++ ) { + args += String(i) + ( i+1 < LIMIT ?
