As well as the site pointed to by Dr. Imre, check out the development
environment that Olin Lathrop has at http://www.embedinc.com/pic/ and
download the files there. The development environment has a large macro
file, which includes useful items like a FIFO macro set, and multiple word
macros for doing 16, 24 and 32 bit arithmetic, as well as some macros that
make thinking about the way the bits work a bit easier.

There are conditional assembly macros that make dealing with bank and page
handling a lot easier. If you always include the "dbankif" macro then the
code only gets inserted if the bank needs changing, so you do not end up
with unnecessary code bloat.

This development environment is designed to be used as linkable modules, and
once you have modules for specific things, then it is easy to include them
in a new project.
