There is NO NEED to switch to Proton, I totally agree.

However you can download a free fully functional copy and use it to view the assembly created by programs written in PICBASIC, for educational purposes the ability to look at chunks of assembly commented with PICBASIC commands is a real eye opener. - As is the ability to single step through the PICBASIC code and watch it execute in a graphical environment.

Downloading Proton Development Suite - Lite from http://www.picbasic.org/ will allow anyone to get a real grip with assembly based upon PICBASIC.

Granted the assembly produced by Proton is NOT the same as the assembly produced by PBP, but the knowledge gained by studying the assembly commented with PICBASIC is fundamental and can be applied to the code produced by the PBP compiler, which as Malanie says "is not Assembler in the true sense of the word"

The transition from writing in PICBASIC to writing Assembler is an arduous one, using the Lite version of the Proton Development Suite will make your life easier and help you get the most from your compiler.
