I've been looking at my program some more.  Got another question.
 

In this example

 

org $0A
loop1var ds 1

org 0
mov FSR,#$30
mov loop1var,#$FF
inc FSR

 

Does FSR now contain $0C or $31?

 

Also if a bank is a 16 byte window does that mean $20-$FF is general purpose?  By that I mean FSR can be set to any of those numbers and everything will be general purpose regeisters.  Or do the global registers carry over to some of those?

 

Sorry if this is frustrating you.  I just got noone to help me here (only one teacher here knows of assembly, but she took it in college and knows nothing of microcontrollers).  I am getting confused by the memory maps.  I attatched a pic of the two maps I have.
