Re: A83:'ret'


That is quite odd, as my client is set in plain text mode.  Of course, if
you couldn't read my old message, you probably wont be able to read this one
either, but oh well.

Just to keep somewhat in the range of being on the topic of calculators,
here's some simple code all those TI-83 Plus programmers might want to try
out:              B_CALL blah
Loop:
       B_CALL blah2
       cp     0Ch
       ret    z
       jr     Loop
(blah = 4D47h)
(blah2 = 4D65h)

(I didn't just B_CALL 4D47h because ZDS will take issue with that).
For those without a TI-83 Plus, the result of this code is a completely
functional mouse/cursor that you can move around the screen, etc.  The
functionality is built into the TIOS, but hasn't been used for anything yet.
