That's certainly better than doing BSF/BCF on RP0/RP1, but still leaves you
open to errors of manually picking the wrong bank.  You could make a macro
that takes a RAM address and sets the banks accordingly.  After all, the
bank is just (adr >> 7).  Now you can reliably set the bank without having
to know which bank, but writing two BSF/BCF instructions in front of every
RAM reference is wasteful.  You could use an assembler variable to keep
track of the current RAM bank, and only generate the BSF/BCF instructions
that are needed.  You could even avoid setting RP1 on processors that only
have two or less banks, or emit nothing at all on processors that have only
one bank.

You could do all that, but you could also download a tested version of this
macro for free.  See my DBANKIF and related macros in STD.INS.ASPIC at
