I'm only sending these messages separately because that makes them
easier to discuss... Anyhow, I'm under the impression that most of
the stuff in an SG needs to have a place to live in the processor when
it is active. Looking at the big pile of accumulators (SGACxx) and
the other slots like regular-pdl-pointer, I am wondering where this
stuff lives. I assume the accumulators need some space in the
processor, but I'm not sure where the other things go. Does this all
live in M-memory? Do parts of M-memory have static meanings? Eg, can
we always expect SGAC1 to exist at (for example) address 1234 in
M-memory? If this latter thing is true then perhaps we should keep
them in distinct slots in the processor object rather than lumping
them all into an array representing M-memory...
Anyone else have thoughts? Or am I just blowing smoke out of my ass
