	Author:		Justin_Flude (Xara Group Ltd) <camelotdev@xara.com>
	Created:	12th August 1993
	Inputs:		An optional pointer to a (constant) Unicode character array - if
				omitted then the String becomes empty (NOT the null pointer).
	Purpose:	Constructs a string of the appropriate maximum length.
	Errors:		ASSERTion failure if the passed character array is too long for
				this length of string, or if psz is NULL.

	Created:	12th August 1993
	Inputs:		A constant reference to another string (can be of any length)
	Purpose:	Duplicates the text of the other string.
	Errors:		ASSERTion failure if this string is not long enough to hold a copy
				of the other string's text, or if the copied String has not been

	Created:	12th August 1993
	Inputs:		A string resource numeric identifier, an optional resource module
				handle (if not supplied, the default resource module is used).
	Purpose:	Loads the string resource into this String.
	Errors:		ENSURE failure if this string is not long enough to hold the
				resource, or if the resource cannot be found in the module. If it cannot
				be found, a very short temp string is built of the form "<%X:%X>" containing
				the ID and the module number, or if that is too long then simply "!".
