Sure, Rob, although I normally ignore messages containing code
written with Parallax's assembler...
The main problem with your code is that you expect RTCC/TMR0 to
run while the processor's asleep. It doesn't.
There are LOTS of other issues, but they're sorta superfluous
when compared to this one.

Actually, I know the RTCC does not interrupt while sleeping. My intent is to
wake up the system with an interrupt from a pin on Port B and then start the
RTCC, and then reset the RTCC after a task is complete and go back to sleep.
Thanks, for looking into this.
