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. + + Author: christine@netscape.com + Date: 12 november 1997 +*/ + + var SECTION = "15.5.4.9-1";
