cbegle%netscape.com 0fbe7f9f59 The JavaScript Test Library, Part I. ECMA v. 1.0. See the page at
http://www.mozilla.org/js/tests/library.html for information about
these tests, like how to run them and stuff.

According to fur, these tests should not get checked out when you
check out Mozilla -- you'd have to specifically check out mozilla/js/tests
to get all these files.

File Name: 15.5.4.5-3.js
ECMA Section: 15.5.4.5 String.prototype.charCodeAt(pos)
Description: Returns a number (a nonnegative integer less than 2^16)
representing the Unicode encoding of the character at
position pos in this string. If there is no character
at that position, the number is NaN.
When the charCodeAt method is called with one argument
pos, the following steps are taken:
1. Call ToString, giving it the theis 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 or is not less than
Result(3), return NaN.
5. Return a value of Number type, of positive sign, whose
magnitude is the Unicode encoding of one character
from result 1, namely the characer at position Result
(2), where the first character in Result(1) is
considered to be at position 0.
Note that the charCodeAt funciton 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.
