Adding PBPro code to an ASM file - how to?

[wjsmarine]

Hi Folks,

I know how to add some asm into my PBPro code but what if I already have a working application (all in assembly) that I want to add some PBPro code to?

Attached a nice SLA battery charger that I want to change from an F88 to an F876 in order to add serial output and LCD with PBPro.

I don't know assembly so any pointers or example to do this to the attached would be very welcome. I'm sure others have come across this before so this may be a common problem?

Kind regards to all,
Bill
