Hello PIC.ers,

Having spent too many hours trying to tease out this one, maybe someone
can point me in the right direction. Before I lose my remaining hairs.
I'm trying to re-jig old 16Fxxx code to the newer 18Fxxx series and
looking to upgrade the rest of my toolchain (esp. relocatable code)
while I'm about it.
THereafter, I can get on with further projects..


Setup:
ICD2, MPLAB 6.30, 18F452.

Source files:  2 off
Main.asm
Maths.asm

Header files:
P18F425.inc            This one is not completely standard-as-issued.
                                I can elaborate if it might be relevant.

Linker file:
p2plsp18.lkr            ie very similar to standard 18F452i.lkr, but with an
.                                extra  SECTION    ROM

Problem & symptoms:
On assembling & linking (ctrl-F10),  the output window shows:
**********************************************
there's  a message (310)
......P18F452.INC 1495 : Superceding current maximum RAM and RAM map.
then

So, all looks well. Then when I look at the output *.map file I see that no
assembling or linking has been done at all. Good as useless y'might say.
I've looked hi and lo for code examples which use macros, but there don't
seem to be any around. The source files main.asm and maths.asm both
invoke the directive
`  #include macros.asm'              at the top of each file.
 Has my problem got anything to do with macros, or should I find another
tree to bark up?

The map file looks as follows:

I'll be helluva grateful to anyone who can give my any leads as to where
to begin with this issue.
