+   File Name:          15.5.4.4-1.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
+
+   In this test, this is a String, pos is an integer, and
+   all pos are in range.
