I know...used the term interrupt in the wrong context...
What I meant to get across was 'a very tight loop, polling the pins, waiting for an event on any of the input pins, and reacting to that input event with an output event on another pin.'
The 10F2xx may not have interrupts, but they do have Wake-From-Sleep, which might be just as good. (just noticed, the 10F doesn't have a RETFIE instruction either!)
