>And a variant record requires an exhaustive listing of it's fields right?<

I don't think so.  Look in the TP manual and see how the type Regs is declared
in the DOS unit.  The variant record is set up so all the fields that may be
variant (AX -> AH AL etc) are at the beginning of the declaration.  The rest of
the registers (ie: the ones that can't be split: SI, DI etc) are at the end,
and are *not* repeated in the second part of the declaration.

Seems to me you could just cluster the variant parts in the beginning, unless
ALL of your fields may be used as bytes or words.  If you need all of them to
be variant, you are right, it might get exhausting.
