TRISA=%00010' This will make A.1 an INPUT == Decimal 2
TRISA=%11111 'All input== Decimal 31
Doh! Yes, I think I see it now. In my mind I was thinking just assigning dec 1 would make all the registers 1 - a short way of saying %11111111 which is of course not correct.
I get it now. Knew it had to be some silly oversight like that.

So then my code on the ANSEL is correct?
Code:
ANSEL = %00000000 'Turn off analog input for ports, set digital I/O
I thought that was pretty self explanatory in the data sheet but I could still have it wrong.
Thank you!
