HIGH, LOW, TOGGLE are OK.

The only way to know for sure is to search through the .LST file for system variable usage.
Thanks Darrel for replying. Conditional branching, interrupt Flag testing and reload of Timer Values thus seems okay. How about moving bytes here and there. Like from the ADC registers to some variable etc. This makes the ISR more comprehend able to PBP users with limited ASM exposure. What about simple MATH like ADD/Subtract or Bitwise operation which are otherwise supported by the instruction set natively ?
