Free TASM clone

[nidud]

JWasm cannot be installed directly in the Borland C++ 3.1 IDE, so you need a 16-bit loader for this to work. The message-pipe system used in the IDE (TASM2MSG.EXE) will not work, so a modified version of JWasm is also needed: http://masm32.com/board/index.php?topic=844.msg7519#msg7519

This will produce the correct error messages that could be handled by the IDE. It also produces the correct debug information (full path to the source files) in the .obj files created.

Hi nidud,

Maybe it may not meet all your requirements but you can check Lzasm :

http://www.phatcode.net/downloads.php?id=308

[mineiro]

I remember a project that is tasm/masm/nasm compatible, but has not been tested on ms-dos, maybe you can try.
Appears to me that this project is freezed, not sure.
http://popasm.sourceforge.net/

[nidud]

The TASM clone is also compatible with MASM.
To use MASM instead of JWASM change the following:

Code: [Select]

JWasm equ <"D:\jwasm206f\jwasm.exe">
space db ' -Zm -zf1'to

Code: [Select]

JWasm equ <"D:\masm32\bin\ml.exe">
space db ' –c -Zm'
If you want to compile all the code snippets in your masm32 directory using the Borland IDE:

Code: [Select]

JWasm equ <"D:\jwasm206f\jwasm.exe">
space db ' '
Compiling the test case made by JJ:

[Vortex]

Checking the site of PopAsm, they don't provide any download for this tool.

Hello Sir Vortex;
try the link below; I was not able to compile it because I'm not good with C, the only language that I learned alone was assembly.
The author does not updated that page posted before, tarball.
