Hey, I like it, all I have to do is negate the initial counter value upon
receipt:

neg32:  movwf FSR               ; 32 bit 2's complement
        comf INDF,f             ; i.e. invert and increment
        incf FSR,f
        comf INDF,f
        incf FSR,f
        comf INDF,f
        incf FSR,f
        comf INDF,f
        ; fall thru

inc32:
        movwf   FSR
        clrz
        incfsz  INDF,F
        return
        incfsz  FSR,F
        incfsz  INDF,F
        return
        incfsz  FSR,F
        incfsz  INDF,F
        return
        incfsz  FSR,F
        incf    INDF,F
        return

And as a bonus: negative zero sets Z, so I can dump the code to test for
receipt of a zero count... VERY COOL! Thanks.
