Hi Guys:

I added the following line in my program & turned off the cofiguration bit
from Picstart menu:

__CONFIG   _CP_ON & _WDT_OFF & _MCLRE_OFF & _IntRC_OSC.  The program is
downloading with success however still doesn't work.

I need to pullup three legs GP0,GP1, & GP3 and turn on a relay.  I have
programmed so far 10 pics, of different setups all of which with no
success:

It can't get anything easier, & yet it still deosn't work:

        LIST P=PIC12C508
#INCLUDE "C:\MPLAB\P12C508.INC"

        __config        _WDT_OFF & _IntRC_OSC & _MCLRE_OFF & _CP_ON


        ORG             0X00                    ;RESET VECTOR LOCATION
        MOVWF   OSCCAL          ;CALIBRATE THE INTERNAL OSCILLATOR
        CLRF            GPIO
        MOVLW   B'00001111'             ;GP0,GP1,GP2,GP3 INPUT
        TRIS            GPIO                    ;GP4,GP5 OUTPUT
        MOVLW   B'10001111'             ;PRESCALER =256
        OPTION                          ;PULLUPS ENABLED, PSA TO TMR0
MAIN
        BSF             GPIO,4                          ;TURN ON RELAY
        GOTO            MAIN

        END
