I am using Picbasic Pro to program a 16F684. What I am trying to do it get pins on portA other than porta.3 to be a input and see a high or low signal. I don't know why this isn't working and I am SURE something will point out the obvious reason it's not. Anyway here is the code below. When I put "high" to porta.0 it doesn't flash the led. I know everything working right because if I just set portc to outputs and set it to flash the same led its fine.

Any help would be great. Thanks!

TRISA=%111111
TRISC=%000000
PORTC=%000000

MAIN:
IF PORTA.0 = 1 THEN
PORTC.0 = 1
PAUSE 60
PORTC.0 = 0
PAUSE 60
ENDIF
GOTO MAIN
