Problems with Z80 Assembler

Question

I trying to write in Z80 Assembler in a CP/M 2.2 Emulator (z80pack) in Debian:

It just says "File Not Found" everytime I try to write a line. I looked for the manual, but it don't say how to start. Is there a especial command I should type? Because M80 (Macro-Assembler 80) also gives error in every line.

I'm guessing it isn't an interactive monitor. Have you tried entering the code to be assembled into a file (.z80) and entering its name into the assembler? In any event I suspect you'll be able to save yourself a lot of grief by going the cross-assembly route. — doynax, Nov 14 '15 at 21:00
@doynax is correct Z80ASM assembles source files. If you want to interact with the symbolic interactive debugger/monitor in Z80 you can run SID instead of Z80ASM. There is some information using SID at this [link](http://rvbelzen.tripod.com/cpm/asuthelp.htm#sid). If you wish to use Z80ASM then you can create source files like TEST.Z80 with the ED command. Instructions on using ED can be found [here](http://www.cpm.z80.de/randyfiles/DRI/ED.pdf) — Michael Petch, Nov 14 '15 at 22:25

You need to create a file containing your Z80 code called whatever.Z80, then provide whatever at the % prompt.

Hence, you can edit your code to alter your program rather than having to retype the entire code perfectly every time.

Given your assembly source file named CONFI.Z80 this command will generate a CONFI.COM binary and a CONFI.LST program listing with a symbol list at the end:

z80asm confi/fxs

Sample run under RunCPM emulator:

A>z80asm confi/fxs

Z80ASM Copyright (C) 1983-86 by SLR Systems Rel. 1.32 #RunCPM

 CONFI/FXS
End of file Pass 1
End of file Pass 2
