Sid,

this is what i did

                BankSel PORTA
                clrf    PORTA
                movlw   D'07'
                movwf   CMCON

It the CMCON register that by default is set for comparator input.

I recently made the big move to 16F628 and this was one of the snags I had
problems with.

The other I still am trying to come to terms with is to take advantage of
the extra ram (which is still not enough) I have to be very wary of bank
switching.  It seems to create a large software overhead and a great cause
of possible bugs.

I use the same KIT81 (I think it is KIT81) for programming so for me it
appears identicle to program as the 16f84.

Justin

I've been thinking about switching to the 16F628 in place of the old
dependable 16F84A.  I've read the data sheet, but naturally, most of it is
over my head.

Question:  How do I set Port A for all digital I/O ?

Thanks
