I won't claim that this rises to the level of a "tutorial", but
I've put up a small linker project at

http://mywebpages.comcast.net/dilatush/lnkrdemo.zip

which at least touches on some of the rudiments of doing
relocatable code in MPLAB.  (It's actually a project I fiddled
with while I was starting to learn MPLINK- a task still very much
in progress- with a lot of comments added for clarity.)

To use it, create a project directory and unzip lnkrdemo.zip into
it; then edit the lnkrdemo.pjt file with a text editor to correct
the pathnames in the [windows] and [mru-list] fields so they
reflect the right paths on your machine; then open the project in
MPLAB and MAKE it.

It's a very brain-dead program, but it goes through the mechanics
of declaring RAM and ROM sections and assigning variables/code to
them as well as making inter-module calls.

I'm just beginning to learn to use the linker, and the biggest
advantage I can see at this point is that it'll allow me to
escape the "namespace clutter" I always seem to get with absolute
code, where every gosh-darn symbol is global in scope.  Sweet!

Hope this helps a bit...
