Architecture, low-level

July 18,


I finally got around to upgrading this page!
For people who have my book, Windows assembly language & systems programming (see http://www.cmpbooks.com/cgi-bin/shopspecific/store/products/087930474X.htm) 2nd ed. 1997, this page is an excellent supplement. In particular, I've put together a complete package of tools for programming with MASM.
Over the years I've accumulated some superb x86-family links, and I plan to keep updating as I find more. So, make this page one of your bookmarks!

GNU C/C++ and MASM (for Win32 programming)
Combining MASM and C files, see my GNU C and MASM page.



C compiler


Borland C++Builder compiler 5.5. The commandline compiler part of C++Builder is free. http://www.borland.com/bcppbuilder/freecompiler. Note also, the famous Turbo Debugger is now free.


LCC-Win32.  This is a great freeware C compiler for 32-bit Windows programming. Has everything: editor, compiler, assembler, linker, resource editor, resource compiler, header files, libraries. Even a rudimentary debugger. The author has worked intensely on this project for seven years. http://www.cs.virginia.edu/~lcc-win32/


DJGPP. freeware 32-bit C/C++ compiler for DOS. http://www.delorie.com/djgpp/


GNU GCC. http://www.xraylith.wisc.edu/~khan/software/gnu-win32/index.html
Also see DEV-CPP integrated development environment below. 


Digital Mars free C/C++ compiler. http://www.digitalmars.com/.



IASM. A basic freeware 32-bit assembler. http://www.dcc.ufmg.br/~augusto/project/


NASM. The Netwide Assembler Project. Free. http://www.web-sites.co.uk/nasm/ , or, http://www.cryogen.com/Nasm.


LCC-Win32 assembler. Free, included with LCC C above. Unfortunately it has a very strange syntax. (if anyone has worked out how to use NASM with LCCWin32, let me know!)


Pass32. http://www.geocities.com/SiliconValley/Bay/9159/pass32.html


MASM. See the Help/Reference/Microsoft DDK section below. Also MASM is in winmasm.zip on this site, see below.



Virtual Windows Class Library. Freeware class library for C++ Win32. http://www.toddtown.com/


DLLs for Win95: http://www.simtel.net/pub/win95/dll/

Text editors
somewhat with


Looking for the perfect editor? This has been an on-going thing with me. Well, I recently discovered one that comes close, and I now use it for everything. It is called ConTEXT, and is FREE and is to be found at: http://www.fixedsys.com/context.
One small detail -- I'm not sure if it's something that I did wrong, but when I opened one of my files, all the tab characters got converted to 8 spaces and after I saved the file I realised that all my spacing was messed up -- because I had previously composed that file based on tab being only 4 spaces. So, I changed the setting in ConTEXT to 1 tab = 4 spaces. But one of my files got messed up before I realised, so just a warning. Other than that, great product. Color coding for asm, C, most languages.


Programmer's File Editor (PFE). Free. Versions for Windows 3.1, 95. NT. http://www.lancs.ac.uk/people/cpaap/pfe/, download: http://www.winsite.com/info/pc/win95/misc/pfe101i.zip


Paws. http://www.godevtool.com/  Another great product from Jeremy Gordon.


AsmEdit: http://asmedit.massmind.org/
It comes with a resource editor that can be used as a stand-alone app.

Micro Asm. http://www.microasm.com/


TASM IDE. http://tasm.freeservers.com/


DEV-CPP: http://sourceforge.net/projects/dev-cpp/ and http://www.bloodshed.net/devcpp.html.
A real nice IDE, uses GNU C/C++ and MINGW, generates Win32 executables. 


VIDE: http://www.objectcentral.com




Free nmake.exe from Microsoft. http://www.hutch.ukshells.co.uk/iczelion/files/nmake15.exe Also see Microsoft Help/Reference sites, below.



Free Microsoft Win32 debugger. http://www.microsoft.com/msdownload/platformsdk/windbg.htm
I don't know why, but I never got this to work properly. I think GoBug is much better (below). 


Free GoBug symbolic debugger: http://www.godevtool.com/.
Jeremy Gordon has developed an excellent free symbolic debugger, that works with executables generated by MASM and Microsoft's LINK, plus others. Go to his site to download "GoBug". To see a make file with switches set to generate symbol information within the executable: bugx.mak. GoBug makes a nice companion to my winmasm toolset. Currently only for Win9x/Me.


Free Borland Turbo Debugger: http://www.borland.com/bcppbuilder/freecompiler.
This only works with the Borland TASM and TLINK. It doesn't understand the symbols generated with Microsoft MASM and LINK. 



ALINK. Free link program. http://alink.home.dhs.org/ and http://anthonyw.cjb.net/


Microsoft linker, see Help/Reference sites, below.

Resource compiler


GoRC. Free resource compiler from Jeremy Gordon. http://www.godevtool.com/


Microsoft RC, see Help/Reference sites, below.

Hex editor

Example asm code


There is an example application that tests the extensibility -- external control and expandability -- of the GOOFEE Diagrammer (my book Flow design for embedded systems 2nd ed. has this on the companion disk). It is written in assembly language, but whatever language you are familiar with, you should find this one readable if you know basic Windows programming and the API. It is a Win95 32-bit application. Download:

w32demo.asm source file, demo GOOFEE Diagrammer companion (Win95)
w32demo.exe the executable.


My book mostly gave example code for Windows asm programming using Borland TASM. However, all the tools for Microsoft MASM programming are now free, and I like MASM better anyhow. So, I've bundled together a complete minimal package of tools, including MASM version 6.14, linker, make, resource compiler and libraries, plus an example skeleton application. All of the tools and libraries were downloaded free from the Internet, and I've included copyright notices where appropriate -- please read them and make sure you agree with Microsoft's conditions before using the tools.


Be sure to retain the directory structure when you unzip this. It will unzip into a folder called winmasm, with various sub-folders.

Symbolic debugger:

Jeremy Gordon has developed an excellent free symbolic debugger, that works with executables generated by MASM and Microsoft's LINK. Go to his site to download "GoBug". To see a make file with switches set to generate symbol information within the executable: bugx.mak. GoBug makes a nice companion to my winmasm toolset.

Dialog editor

I need a good free dialog editor to complete this download package. You use this to graphically design dialog boxes. This app will generate a ".rc" file that the resource compiler "rc.exe" can compile.
