Which assemblers can forward reference zero page ?


Recommended Posts

I'm working on disassembling the PL65 compiler and it's got some weirdness in it that's for sure. One thing is that a lot of zero page references use the absolute address version of the instruction rather than the zero page version. So there's a lot of this:

 

STA $0080 (8D0080) instead of

STA $80 (8583)

 

I'm just wondering what assemblers can do that ? I know EASMD does, Six Forks does, and MAC/65 most certainly does not. What assemblers will let you forward reference zero page variables before they are defined ? We're talking 1987 here, so the guy wasn't using mads or anything like that.
