        Ok, Alex. I have a piece of extracted code from a old project, for 3
displays and 8 leds, in a PIC16C71 at 16 MHz:

; Display Variables (consecutive)

        Display1   equ xx+0
        Display2   equ xx+1
        Display3   equ xx+2
        LEDs       equ xx+3

; Auxiliary Variables

        Aux1
        Aux2
        Counter

; I/O

#Define DISPCLOCK  Port_B,0
#Define DISP_DATA  Port_B,1

; Routine

WaitP   clrwdt
        nop
        nop
        nop
        return

Digit   macro
        movwf    Aux1
        movlw    8
        movwf    Counter
LoopDisp
        bcf      DISPCLOCK
        rrf      Aux1,Same
        bcf      DISP_DATA
        btfsc    STATUS,CARRY
        bsf      DISP_DATA
        call     WaitP
        bsf      DISPCLOCK
        call     WaitP
        decfsz   Counter
        goto     LoopDisp
        bcf      DISPCLOCK
        call     WaitP
        endm

StartP  macro
        call     WaitP

        call     WaitP
        bcf      DISPCLOCK
        bcf      DISP_DATA
        call     WaitP
        endm

Stop    macro
        bcf      DISP_DATA
        bcf      DISPCLOCK
        movlw    3
        movwf    Aux2

        call     WaitP
        bcf      DISPCLOCK
        decfsz   Aux2,Same
        goto     StopLoop
        call     WaitP
        endm

Display
        StartP
        movlw    4
        movwf    Aux2
        movlw    Display1
        movwf    FSR

        movf     0,w
        incf     FSR,Same
        Digit
        decfsz   Aux2,Same
        goto     DispLoop
        Stop
        return

        Good Luck.
