You could use an edge-triggered interrupt on one of the RB pins, but this might be a little easier:

[code]  
DO WHILE AbortBtn = No
  PAUSE 50
  INC ledTmr
  IF ledTmr = 20 THEN
    Led = ~Led
    ledTmr = 0
  ENDIF
LOOP[/code]

This checks the abort button 20 times per second, instead of once per second as with your code.
