Sorry, I spotted that after I posted but this is still not working...

I've added

=========================================

ADCON1 = %10000100 ' Set PORTA analog and RIGHT justify result
ADCON0 = %01000001 ' Configure and turn on A/D Module channel o Fosc 8

=========================================

and changed

=========================================

Adcin 0, PotVal

=========================================

I don't understand registers. I've read the PIC16F690 DATASHEET a couple of times. I seem to handle these issues best using the "Monkey see... monkey do" philosophy when trying to grasp complex problems. (Maybe the Monkey see, monkey do is part of my African heritage )
