z80: remove layer of indirection in most "next" calls The only calls still using the stable ABI indirection are those made before the next routine is created. 2020-06-18 07:24:47 -04:00			`lblnext BSET PC ORG @ 0x1b + ! ( next )`

z80a: make mnemonic names more uniform across assemblers Initially, I used the same letters as those used in the z80 ref docs, but it makes the different assemblers harder to use than they should. Having consistent "argtype" rules across assemblers should help. 2020-06-27 22:01:56 -04:00			`( PS ) HL PS_ADDR LDdn,`

z80: use named labels for boot routines The usage of numerotated labels for this was becoming severly confusing. 2020-06-18 07:16:40 -04:00			`JRC, lblofl BWR ( abortUnderflow-B298 )`
