I agree with Olin.  I need help understanding difference between MPLAB and
the c compiler (in this case c18) and you have helped.

I have had good success using the IDE for assembler with all my own code but
this is my first project with c and its modifying the Microchip stack. .

I could start with a simpler project perhaps but I am certain if I just get
over a few hurdles I should be ok.

I find these processor directives difficult because I cant tell what the
processor thinks their values are.  I managed to work out how to pass a
structure by reference because the debugger gives me feedback.

Is there a directive that I can use to echo the value of the various defines
or better yet is there documentation that describes these directive.  What
confuses me even more is that some people put these in a section of their
code called Macros.

>From what Olin has said these must be c18 directives so I will go thru all
the c18 help files and c what I can find.

Cheers Justin


Step back and understand the distinction between MPLAB, your C compiler, and
