Ever done OOP programmes? You can (sort of) do encapsulation of your code in
assembler using CODE sections. It does not totally stop you from stuffing
things up (especially in machines with banks, and you forget to make sure
you are in the correct bank) but it does go a long way towards helping
separate things and stop one lot of code from stepping on another lot.

It also allows you to have modules that you can re-use. I now have modules
for I2C (both master and slave) built from the Microchip app notes, Serial
Comms with UART built from Fr. MacGhees picuart file, and an analogue
module, along with a number of miscellaneous others. These were all done
using Olins development environment, and are all re-useable modules by
linking them in.
