Hi Butch,
Check out this bit...

ILOOP:
I = I + 1
IF I = 5 THEN
GOTO BASE
ENDIF
GOTO ILOOP


When interrupted, that will just increment 'I', jump back to 'ILOOP, then go back to 'BASE' when 'I'=5, never blinking the LED.

BTW - the 'MYINT' should terminate with a 'RESUME' - don't know what will happen the way it is in your code.
