  • Problem with SPASM assembler

    From Zbig@21:1/5 to All on Mon May 30 10:34:13 2022
    Hello,
    I downloaded spasm.zip assembler/linker from the site http://www.cpm.z80.de/emulate.html , but I met a problem I'm
    unable to solve: although spasm.exe generates .obj file, the slink.exe
    linker _always_ complains FILE READ ERROR and it deletes .obj file
    I tried to use to create final .com file.

    Perhaps somebody can make any tip, how to use slink.exe to make it work?
    Maybe some docs are available (the package contains just short readme)?

    I work within FreeDOS environment

    OK, I guess I traced the problem.
    Example of proper use: „slink test=test.obj”.

    So not just „slink test.obj” neither „slink test.com=test.obj”. Only like the above.

    Using DOSEMU, I can confirm that.


    SPASM.EXE works.
    SLINK.EXE does nothing ???

    Btw, I used the following example.

    hello.asm
    ==== 8< ====
    org 100h

    lxi d,hello
    mvi c,9
    call 5
    ret

    hello: db 13,10,'Hello world!$'
    ==== 8< ====

    So, these two programs are clearly *NOT*
    very usable, if you want to run them as
    cross development tools.


    But if you want to use these programms for historical
    reasons and have the possibility to run them natively
    or under an emulator, there is a solution!

    Cut off the first 4480 bytes and name them .COM.
    Both are then running fine under any CP/M emulator!


    So, assembling, linking and running the example...

    spasm hello

    Thanks, that works!

    Tried out several combinations, just not this mixed one...

    UPDATE:
    Slightly older versions of SPASM and SLINK, *with* documentation and
    with the library manager "SLIB" are in

    <http://www.retroarchive.org/cpm/cdrom/CPM/UTILS/ASMUTL/SPASM201.LBR>
    Thank you! :) We can combine one decent package from the two.

    I wanted to practice some 8080 assembly even before I select and install full-featured CP/M emulator for DOS. And even later it may be practical to have cross-assembly ability.

    Unless you have a specific need for an odd assembler why use one?

    Only slightly more complicated is CP/M Executor but with the advantage
    you can run native CP/M binaries.

    p.s. the 'command dest=source' syntax applies to most DRI tools.

    When it says "with attached MS-DOS emulator" that's literally correct.
    I found that removing the first $1180 bytes of SPASM.EXE and saving as
    a COM it worked fine under CP/M. Checking with an existing DRI ASM
    file it only complained about the 'TITLE' directive. I didn't test
    further. While the author appears to have put a lot of work into
    SPASM I can't say I ever heard of it before this.

    Thank you, I'll try that.
