Does anybody see any problem with the following
32-bit increment, other than it not being
isosynchronous ?

; 32-bit increment-------------------

       INCFSZ   COUNT_0,F     ;  LSB
       GOTO     DONE          ;
       INCFSZ   COUNT_1,F     ;
       GOTO     DONE          ;
       INCFSZ   COUNT_2,F     ;
       GOTO     DONE          ;
       INCF     COUNT_3       ;  MSB
DONE:

;------------------------------------

I am also looking for a 32-bit add, subtract,
and compare snippets.  The subtract could be
used for the compare if Z is valid after the
subtract.
