That part, believe it or not, is correct. It gets set elsewhere, in
another assembly routine. The part that really seems to be giving me
trouble is this:
jsr [0xA000] ; call POLCAT
where the routine will stay in a loop even if I press a key. The BASIC
manual says that Z will be 1 upon finding no key pressed, but 0 if it
is pressed. But my code doesn't seem to be reacting that way.
