Hi,

What PIC do you use? Port A usually contains a lot of stuff such as comparators and A/D and there fore requires some more registers to be set before it is working properly.

What do you have connected to your port A and what do you want it to do? Do you want all pins digital? or just some and the others A/D.

To help you we need some more info such as mentioned befoer PIC, simple circuit description, a clear idea of your expected end result and some beer.

The beer most of us already have so you just add the rest and we will see where the problem is.
