I have some trouble understanding bank access on a PIC18F8722. More specific the "a" bit in an instruction. Can I just set the "a" bit to 0 and not bother with bank selection? Does this apply for the GPRs (60h to F5Fh) only? Or can I access the other registers as well?

I'm wondering because I don't want to have to keep track of which bank the registers are placed in. On the PIC16F628 that I have been using up until now, I only had to use data from Bank1 on rare occasions. On the PIC18F I will have to use a large number of GPRs, and it would be a pita to keep track of it all.

I'm using MPasm for compiling and I only program in assembly. I have written several routines for the 16F628A for SD cards and FAT16 file systems. Now I will have to move on to the 18F series for faster speeds and a better instruction set. Are there any tips and tricks I can use that MPasm understands?

Thanks for your help.
