PIC and memory buffers (banked access)

Re: last post..  Trouble is of course that 1. PIC is a pain to use an
2. abstraction solves everything.  (and 3. I have to accept these
things ;)

However, thinking in assembly it seems that what is needed is a way to
use banked addressing.  The pointers themselves are in a fixed
location so not necessary to use the 'a' register here..

Let's define the words @b, !b, b@, b! that perform the banked access
and access to the banking registers.
