z80a: make mnemonic names more uniform across assemblers
...
Initially, I used the same letters as those used in the z80 ref

should. Having consistent "argtype" rules across assemblers should
help.

z80: optimize chkPS
...
Inline it in next and make chkPS, call a newly reserved label for
it directly, removing a layer of indirection. This frees a spot in
the stable ABI.
