I exclusively use object mode and the linker.  It eliminates the need for
"manual" control over some things, and of course each module gets its own
local namespace.  This is clearly the way to go for anything but a toy
project.

However, the binary library idea won't work as you think.  The problem is
that each project has a little (sometimes a lot) different configuration.
This includes different processors, different banks reserved for things,
different size and location of the software stack, etc.  The linker isn't
flexible enough to allow one precompiled object module to be configured for
the different setups at link time.  To get around this, my libraries of
standard routines are source code include files instead of object files.
Each project that uses a library routine has to create a 3 line module that
references the project configuration include file, the library routine
include file, followed by the END statement.  For example, here is the 24
bit floating point multiply module for the HED project:

         include "hedlib.inc"
         include "..\pic\fp24mul.inc"
         end

For a wider discussion of how I use the linker, include files, how I break
up projects into modules, and template standard modules see
