I see your point. But the flaw in the code is not the underlying problem. It should flicker while the button is held down. And then land on ON or OFF 50:50, right? I changed the pause to 1000 and it's still the same. Yes, I have the a 10k pull up resistor to Vdd. Does the config section look correct? For some reason, the TRIS reg didn't cut and past completely. It should be

TRISA = %11001000

Does that look correct?
Do I need to do something with the C registry?
