PIC18 Pseudo-Instructions

Hi. Can anyone advise please? 

I'm migrating code from a base device to a PIC18Fxxx. No real problems
except the original code uses Pseudo-Instructions and I can't find
equivalent(s) for the higher-end devices. Do they exist for the 18F
parts or do I have to take say, CLRC and use BCF STATUS,C instead? 

Cheers, 
Simon

AFAIUI, Microchip is discouraging the use of pseudo instructions even
for the 12 & 14 bit cores. I think it's a good idea to get rid of
them, particularly the ones that generate more than one instruction. 

If you must have them, simply write some macros, but I would
definitely use upper case so it's obvious that they are macros.

Thanks Spehro - someone on the Microchip forum has suggested Macros as
well. I'll do this instead.

Strip off the pseudo-instructions.

Macros done - code runs perfectly!
