I have tried your code and suggestions, but I still cannot get the poll button to become active. I hooked up an LED to rb.0 to watch the state of pin ra.0 and I noticed something else that seems odd to me aswell. I am under the impression that if I set rb.0 to an output and then say HIGH RB.0 that the pin will go high. I thought the was pretty much the same thing as saying RB.0 = 1. Likewise I should be able to use RB.0 = 0 and LOW RB.0 interchangably, right?

Consider this code:

output rb.0 
input ra.0

Start:

if ra.0 = 0 then
	rb.0 = 1
else
	rb.0 = 0
endif
GOTO Start

Compared to this code:

output rb.0 
input ra.0

Start:

if ra.0 = 0 then
	HIGH rb.0
else
	LOW rb.0
endif
GOTO Start

When I hook an LED up to RB.0 and press the button on ra.0, the led blinks as expected with the bottom code... but nothing happens at all when I press the button using the top code. Is this what you guys would expect? Thanx for your continued support. I'll figure this thing out sooner or later ;)
