Re: LZ: Couple of questions.
The VAT is the Variable Allocation Table, stores information on where the
Variables are stored. There is a Text file on TICALC.ORG explaining how
the VAT is structured.
IX, IY are index registers. AF is a two byte register pair of the
register 'A' (I hope you've heard of that one...) and the flag register
(ie, when you jr z, wherever, z is a flag). Not used in two byte form
very much except for pushing and poping.

We all come into the world the same way - naked, screaming, covered in
blood. But if you live your life right, that kind of thing doesn't have
to end there.
