Thanks for the framework for implementing an ISR in PBP.

I concur with the comments regarding moving to C and using Microchip's IDE. I have started down that path on numerous occasions, but overcoming the inertia of being able to use PBP to easily do what I wanted was too great of a barrier for me. While it can be laborious to use PBP to implement some of the newer PIC peripherals, it can be done. For me, PBP's problem is that the language does not effectively deal with interrupts. As a friend of mine says "You do not fix a problem. You eliminate it." Given that it appears that PBP has reached its maturity, it is time for me to eliminate my problem an learn C. Painful.
