Hi,

I had never heard of that,

   Ah, well it was fairly short lived, I suppose.  But it was fun to
try it out.

but yeah, like that. Except that it wasn't anything like a multi-user multitasking "environment", just an overlay on top of DOS programs. It sure looked like the screenshots of the IBM thing, though.

   Well, I was wondering about that.  Nice to hear about it.

Thanks,

Steve N.

The Campus / Re: Nested .REPEAT, .IF and .W...

Last post by Quan - Today at 07:18:14 PM

Adding to this, I'm essentially trying to replicate this chunk of code in a macro so I can use it multiple times.

Code Select Expand

xor eax, eax
mov esi, offset strHW
loop_start:
inc eax
mov edi, offset strHW + 5
add esi, eax
xor ecx, ecx
add ecx, 11
cld
repe cmpsb
jz found

cmp eax, 10
jne loop_start

found:
mov ebx, -1
Is anything I'm doing wrong or unconventional?

EDIT: Minor, unrelated logic error, cmp instruction at the end of the loop is supposed to compare eax with 10, not ecx with 10.

The Campus / Nested .REPEAT, .IF and .WHILE...

Last post by Quan - Today at 07:12:40 PM

I have this simple programme here

Code Select Expand

include \masm32\include\masm32rt.inc

testing MACRO
xor eax, eax
mov esi, offset strHW
.REPEAT
inc eax
mov edi, offset strHW + 5
add esi, eax
xor ecx, ecx
add ecx, 11
cld
repe cmpsb
.IF !ZERO?
GOTO found
.ENDIF

.UNTIL eax == 10
:found
mov ebx, -1
ENDM

.data
data_start EQU $

strHW db 'Hello World!', 0
    strQuery db 'test32.exe', 0
   
.code
start:
testing

push 0
call ExitProcess
end start
and I'm getting this error here.
C:\3\test.asm(35) : fatal error A1010:unmatched block nesting : .if-.repeat-.while

I think my syntax is correct. Am I missing something? Or .if being nested in .repeat is not allowed?

EDIT: The condition in .UNTIL is supposed to be eax == 10 and not ecx == 10. The same error is still produced after this edit.

Cross platform, wrapper functions
Like proc with winapi function names,inside is invoke to Linux same function?
Or the other way around?

Congrats!

Thanks. Maybe you want to try it sometime?

Hi,

I once wrote a pretty good text-based windowing system for 16-bit DOS apps. Worked pretty well: using 80x25 screens you had input and output fields, full control of color and several useful "gizmos" like pop-up boxes, "gas gauges", etc. Kind of like the old *nix-based curses package. Fun stuff.

  Like IBM's Topview perhaps?  Interesting.

I had never heard of that, but yeah, like that. Except that it wasn't anything like a multi-user multitasking "environment", just an overlay on top of DOS programs. It sure looked like the screenshots of the IBM thing, though.

The original one I wrote in the late 1980s was written in assembly language. Later I wrote a similar but less extensive package that I called the "Gizmo" package, also for DOS programs. That one was written in C and used the curses library.

ObjAsm / Re: New Editor

Last post by Biterider - June 19, 2025, 03:15:09 AM

Hi
Today was an exciting day! I ran a Lua script in the editor for the first time. 

After spending a few hours setting things up, I ran a simple 'Hello World' print command from within a Lua script.
Initially, I couldn't see anything because I had forgotten to update the view. However, as soon as I scrolled down a bit, there it was! It looked great!  

Designing the interface between the script engine and the editor is challenging because I don't yet know exactly which commands I will need. I'll start with a small set of commands and extend them as necessary.

OK, thanks very much, including for the well-stated, and thorough number of, options!

Hi Greg,

Microsoft crippled ML64, so invoke, .if .else .endif, .Repeat ... .Until and others are no longer built-in. Therefore you basically have three options:
1. Bare metal: no macros (for Real Men^TM)
2. The macros developed by Hutch and Vasily in the Masm64 package
3. UAsm or JWasm

Note that Vasily's invoke does not check for the number and/or type of parameters passed. JBasic's jinvoke does, but it's work in progress.
