all depends on your clock speeds for delays...but this seems to work for me


DEBNC   macro   port,bit
        btfsc   port,bit        ;  Is the Button Pressed?
        goto    $+8             ;   No..so skip past this debounce
        movlw   0xFF
        movwf   Dlay
        decfsz  Dlay,1
        goto    $ - 1           ; wait for delay
        btfss   port,bit        ; If the button is active...wait if the button is still
active
        goto    $ - 1           ;   wait for it to become inactive
        endm
