swmuex DEPRECATED

	CALL SWMUEX( MUXSWD )

	This subroutine will handle the updating of a set of mutually exclusive
	touch panel switches.  It should be called at 15 Hz.  Whenever  one  of
	the switches in the  set  is  touched,  that  switch  will  become  the
	selected switch, the color of the text associated with that switch will
	be written in reverse video and the text  of  the  previously  selected
	switch will be written in normal video.  MUXSWD is an  INTEGER*2  array
	which contains the decsriptor for the mutually exclusive switch set. It
	is structured as follows:

	WORD		CONTENTS

	 1	Number of switches in the set (N)

	 2	Currently selected switch number.  This word should be  set  to
		the switch number of the default selected switch before  SWMUEX
		is called for the first time.  The text for that switch  should
		also have  been  written  in  reverse  video.   If  no  default
		selected switch is desired this word should be set to -1. After
		calls to SWMUEX this word will be set to the switch  number  of
		the currently selected switch (or -1  if  no  switch  has  been
		selected).

	 3 to	These words contain the switch numbers of the switches  in  the
	 N+2	set.  All switches in the set should be defined with attributes
		momentary, off, and auto-color-change disabled.
