Well, you have helped a lot, thank you!! but I rewrote the architecture on Michael's suggestion...
( the byte /word /integer part I already figured out.. You need word btw, not byte, to handle ordinals on current processors that handle up to 512 (exotics even more) per register and are just not yet implemented, same as current 64)
Anyway, the discussion made me rethink some parts in a fundamental way.
