Alternative for CP/M assembler M80&L80 for DOS/Win32-solved (Users)

Yes, you're right. I analyzed tools that CPMish use and found this ZMAC:
http://48k.ca/zmac.html
It has switch for 8080.

But there's one small issue. For some reason it doesn't like a label named "PO" - maybe some keyword?

ZMAC.EXE -8  MON40F.MAC
MON40F.MAC(223) : Syntax error
        JMP     PO      ; PUNCH OUTPUT <C>

MON40F.MAC(96) : Phase error - $0002 changed from $00 to $04
        JMP     COLD    ; COLD START

After I renamed the label to "POUT" both errors disappeared and I got compiled binary. I compared it to original M80 output and it the same. So I think I can use this...
