SKPNC means 'Skip on No Carry' and SKPZ means 'Skip on Zero'.  They are
equivalent to the following:

#define SKPNC  BTFSC 3, 0     ; Skip on No Carry
#define SKPZ   BTFSS 3, 2     ; Skip on Zero

The following can also be used:

#define CLRC   BCF   3, 0     ; Clear Carry
#define SETC   BSF   3, 0     ; Set Carry
#define SKPC   BTFSS 3, 0     ; Skip on Carry
#define CLRDC  BCF   3, 1     ; Clear Digit Carry
#define SETDC  BSF   3, 1     ; Set Digit Carry
#define SKPDC  BTFSS 3, 1     ; Skip on Digit Carry
#define SKPNDC BTFSC 3, 1     ; Skip on No Digit Carry
#define CLRZ   BCF   3, 2     ; Clear Zero
#define SETZ   BSF   3, 2     ; Set Zero
#define SKPNZ  BTFSC 3, 2     ; Skip on Non Zero

You can embed these mnemonics in the P16Cxx.INC file and make them available
to all your programs automatically.  You can probably come up with more if
you like.  The problem with these short cuts is just what you discovered.
Other people who look at your code may not know how you have defined your
mneumnics and get lost.  They may make your code more readable to you, but
maybe not so readable to others.  It's your call whether you think this is a
good practice or not.

Hope that helps.  DRC  :->
