Another approach is to define the variable in the asm and put it in the
access bank. Both C and asm can then find it without messing with the bank
select register. I do this a lot for small variables. Another approach
that I use for arrays that would take too much space in the access bank is
to use an FSR to access the variable. You have to save away the FSR and
restore it for the C code later.
