Zoot,




<B>You said...
"bank 0" registers are really at $10-$1F and can *only* be accessed as follows: 

CLR FSR
MOV fr, W  ; where fr is $10-$1F

[/quote]Yes, for sx48/52.
For sx18/20/28, bank0 is $10-$1F




<B>You said...
But that $00-$0F are always the globals, e.g., without having to change banks or set FSR: 

MOV fr, W ; where fr is $00-$0F
(that doesn't sound right; wouldn't FSR.4 have to be 1 to get the "globals"?)
</B>
[/quote]Yes, and you don't need to set fsr.4 for the globals
You must set fsr.4 to access any bank via $10-$1F on sx18/20/28
And you can use indirect addressing for the globals except IND.
mov fsr,#5
clr ind  'this actually does clr ra
