[A83] Re: IX and IY
nope. IX and IY are made up of 2 separate bytes each, but are always
paired.
IX is made of IXH and IXL. Only a special TASM table lets you use those
registers unpaired, and instructions that use them take up 2 more bytes than
normal instructions. (you add a couple bytes to the beginning of normal
instructions that use H or L, and they use IXH and IXL instead)
There's also an I register, used for interrupt programs. That register has
nothing to do with IX or IY.
