You may want to try Setting this Flag before your "call _getkey"... "SET 
indicOnly, (IY+indicFlags)"  Ive never used it myself, but the TI ducuments 
say "1 = Interrupts will only update runindicator and not flash the cursor or 
APD" so I assume that means the APD will not occur if this flag is Set. You 
should also do "call _runindicoff" again i suppose. Oh yeah, and before you 
exit your program do "RES indicOnly, (IY+indicFlags)", just to be safe... 
Keep in mind Ive never tried this myself, but it looks alright. If anyone 
knows otherwise, please correct me... :)
