Can anyone please tell me why the following Pic16C84 code doesn't work!
;
count equ 0c
countn equ 0d
countm equ 0e
shift   equ     0f

    org 000
start
    movlw 00           ;set port B
    tris portb         ;           for output
    clrf portb         ;all lines low (8 LED's off)
;
    movlw .9           ;number of
    movwf count        ;          shifts
;
    bcf status, c      ;clear carry flag
    movlw b'00000001'  ;store
    movwf shift        ;      pattern
;
repeat
    movf shift, w      ;get pattern
    movwf portb        ;display pattern
    call delay         ;                slowly
    rlf shift          ;rotate pattern left
    decfsz count       ;count-1 to count register by default
    goto repeat        ;LEDs flash one at a time from right to left
done goto done         ;program never gets to 'done'!
;
delay                  ;Easy PIC'n pause routine(delay works great)

    movlw 0ff          ;m
    movwf countm       ;  to counter
loadn
    movlw 0ff          ;n
    movwf countn       ;  to counter
decn
    decfsz countn      ;decrement n
    goto decn          ;again
    decfsz countm      ;decrement m
    goto loadn         ;again
    return             ;done

Thanks for the help,
