It has been suggested I write some macros to simplify my code. I haven't used
them before. The MPASM assemblers guide is limited. I have a couple of
questions. Please note I am a beginner

In my code I am struggling to keep table and references to the PCL within the
first 255 addresses. The guide states macros must be defined prior to their
use. If I define them at the beginning of my code will they occupy those
addresses?

     Macros occupy NO code space. When they are invoked they generate code
     that DOES take up code space.

Is it appropriate to define macros using an include file and simply make
reference to them at the beginning of the program?

     Yes.

Is there a straight forward tutorial that could help me understand how to
implement macros? I have all the most popular PIC books but they don't go into
macros.

     Macros are fairly easy to use, get the MPASM reference from the Microchip
     web site. The chapter on macros is only a few pages long.

Is the Parrallax assembler a compilation of macros?

     Can't answer this one for sure, but I would guess not, although it does
     support macros.
