Can't make RA1 a digital Input on (10 out of 20) 16F887.

Try this wild guess:

IF PORTA.1 = 0 THEN
PORTE.1 = 0
ELSE
PORTE.1 = 1
ENDIF

EDIT: I also went through the datasheet and can't see any register you could have forgotten.

Thanks for the reply.

I gave that a try and still have the same results. I was originally using variable names for each pin, but removed them to simplify.

I have done a lot of programming without problem. Can't believe I can't make an input work.
In my larger program, I actually save this pin state to a USB flash drive. The input is always 0.
The ANSEL = 0 and ANSELH = 0, is working for all the other pins they deals with.

Found it:

TRISA = %000000010

I count 9 digits.
