IMHO, it's *much* better to just set the environment to be *not* case sensitive. Yes, there have been code posted to the PIClist lately where the was two *different* symbols called "PORTA" and "portA" (or something similar). Realy bad coding standards, if you ask me :-) Then it could be good coding practice to *write* TMR0 in uppercase in your code anyway, it might give a better readability.
