Mine Sweep, a take-off from the classic windows game,
is relatively simple to operate.  When the menu asks
for the row, you enter which row of mine squares you
wish to play on.  It then asks you which column, and
where the two cross is where the spot is.

The source code is open to anyone to modify, and if
you improve it I would like to know, so e-mail me at
poweriu@mailexcite.com.  

I plan to include cursor control eventually.

The two included programs (besides mine.83p) are 
zinvtext.83p and znrmtext.83p, which are useful in
many other applications, and include a bit of assembly
code to inverse your screen font.
