You can still merge programs and data as normal. The 67 runs business as usual, it isn't aware of the extra memory, only the user, so all the original operational rules still apply. With the extra memory though, you might not have to merge.

I guess you could do a return from a subroutine in a different PGM bank but execution would continue from the calling address + 1 in the new PGM bank. Might be useful if you keep track of what you are doing though.

Bank switching program memory will have a mechanism to jump to any label or continue from the current PC address in the new bank.
