Assembler: please kick me in the right direction

[Demon]

Hi,

I have assembler code that I'd like to integrate into my PIC Basic Pro application. The only problem is that I haven't touched assembler since 1980, so I'm very rusty (make that totally ignorant by now).

I'd appreciate any help in finding a tutorial to better understand this stuff. One problem I have right now is how to identify the pins. I also foresee compatibility problems, no idea what version of assembler this is in.

This is the code for an Optrex 51553 graphic LCD. I also have on hand the 2 include files at the end; the image and font definition.
