DevGuru WMLScript Function: String.length



			FUNCTION: String.length String.length(string) The String.length function returns the integer length of a given string. If the string is an empty string, a zero is returned. Note that you can use the String.isEmpty function to determine if a string is empty (i.e., has zero length). The mandatory string parameter can be any string containing zero or more of any combination of characters (including white spaces). This parameter can also be an empty string.
