That isn't the only thing that needs changing.  Other things that need
changing are:

 o  handling of the custom menu (the UCML program in 411 needed to be
	completely rewritten)

 o  blocking keyboard input can now be performed with 0 WAIT

 o  keyboard input (via KEY or WAIT) is now given in terms of keyboard
	location, rather than strings.

Has anybody else noticed other problems porting 28S code to the 48SX?
