Hi all,

I'm new (2 days now) to PICs and am working on a project that involves
reading weigand RFID signals, storing the ID numbers in memory then
transmitting them via RS232 to a computer in a big batch.

As a "build-up" to this, I'm trying to get an LED flasher to work, then an
RS232 broadcaster, then a weigand reader, then finally the weigand
reader/re-transmitter.

I'm using a 16F88, as it seems to have more than enough capability and isn't
too expensive; programmed in assembly language in MPLAB. The code for the
LED flasher and RS232 are here:

http://web.mit.edu/cosic/www/PIC/

The issue I have is with setting up the device I/O - this is the error I get
when compiling:

"Message[302] C:\RFID\RS232.ASM 51 : Register in operand not in bank 0.
Ensure that bank bits are correct." 

Page 15 of the datasheet says that TRISA, TRISB and ANSEL are in 'Bank 1'.
Page 11 describes the Settings for STATUA, RP0 and STATUS, RP1 needed for
bank 0.

I've played about with my code to no avail - I still get the error during
compile about the register not being in bank 0. (though it seems to simulate
just fine).

Any chance somebody more experienced could take a quick peek at the code for
me please? (its lines 18 and 19 on the LED one, lines 51, 55 and 56 on the
RS232 one) Replies off-list would be great.

Thanks!

PS - using the following exemple code from page 53 of the datasheet also
flags up the same compile errors:

BANKSEL PORTA ; select bank of PORTA
CLRF PORTA ; Initialize PORTA by
; clearing output
; data latches
BANKSEL ANSEL ; Select Bank of ANSEL
MOVLW 0x00 ; Configure all pins
MOVWF ANSEL ; as digital inputs
MOVLW 0xFF ; Value used to
; initialize data
; direction
MOVWF TRISA ; Set RA<7:0> as inputs
