The point is that you need to make sure the target string is already 4
bytes long (or whatever) before you call strcpy, or you'll be in
trouble.   You might write the code as:

	len = strlen (sourceStr)
	destStr = String (len + 1, 0)
	strcpy (destStr, sourceStr)

This ensures that the destination string has enough space in it.

If this is not your problem, then I don't really know what to suggest.
