A83: Sv: Problem with _dispop1a

As far as I _remember_ the number in reg. a determine how many digits to be displayed of the number in op1. That's way reg. a has to be bigger than 0 and lower then 16.

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
