Re:   RESOURCE and REZ...

Herb;
       ASM will take tdl mnemonics except for the non-8080 z80 instructions;
(that's because tdl starts with the intel 8080 instruction set & adds more
--in the same style-- to cover the extra instructions used by the z80).
If you try assembling them, you will get an error message; If you really want
to, you can then translate the z80 instructions into 8080 instructions. (there
are macro's for doing this with the MAC assembler).  Most software that doesn't
explicitly require a z-80 to run use only the 8080 instruction set (which is 
also compatible with 8085's): So when these are disassembled to tdl mnemonics, 
the disassembly should contain only the intel mnemonic 8080 instructions. This 
means you won't have to do any z-80 translation.
       REZ runs on z-80's under cpm. I think Christiansen wrote it in 8080
assembler so it should run on 8080's and 8085's too.
