A83: Problem with _dispop1a
I'm making a game, and I use the code wich is under. It displays
the register's value a on the screen at the position of penrow, pencol, but
when a is 0, the TI returns an UNDERFLOW error and breaks the program. Does
someone could say me why and how can I do to display the value of a on the
graphic screen with this routine or with another ?
call _setxxop1
ld de,19*256+68
ld (pencol),de
call _dispop1a
ret
Thanks
