	After 'losing' a 28s under mysterious circumstances I cobbled
together a little program called "OFF" that put my name and address on display
and then shut the machine off using a SYSEVAL.  With the 48sx its quite simple
to write a similar program that uses the RPL command OFF and then reprogram
the OFF key to call the program using the USER keyboard mode.  Now whenever
anyone turns my calculator off, it puts a big obvious message on
display about who owns it etc.
	I figure that it will make it a little bit harder for a thief to
be a thief and should I truly lose the thing, it will be quite easy for
the finder to locate me.  Now if a guy were really smart he might take
the batteries out (or find some manuals somewhere that explain what's
really going on the with the calculator), but its a big step in the
right direction.  If anyone is interested in the trivial code required
for such a program, e-mail me.
