Microsoft Assembler Masm Free Download
The Microsoft Macro Assembler (MASM) is an x86 assembler that uses the Intel syntax for MS-DOS and Microsoft Windows.Beginning with MASM 8.0, there are two versions of the assembler: One for 16-bit & 32-bit assembly sources, and another (ML64) for 64-bit sources only. MASM is maintained by Microsoft, but since version 6.12 it has not been sold as a separate product. JWasm is a free MASM-compatible assembler with these features: native support for output formats Intel OMF, MS Coff (32/64-bit), Elf (32/64-bit), Binary, Windows PE (32/64-bit) and DOS MZ. Precompiled JWasm binaries are available for DOS, Windows and Linux. For OS/2 and FreeBSD, makefiles are supplied. Instructions up to AVX are supported. JWasm is written in C.

Note that MASM32 will not install on a network drive.MASM32 comes with its own runtime library written fully in assemblerand an extensive range of macros for improved high level emulation andfaster development. It builds its own IMPORT libraries for the WindowsAPI functions and supplies its own include files for a very largenumber of API functions.
The default editor in MASM32 has been fully recoded fromscratch in MASM and it is smaller, faster and more powerful with two(2) separate scripting engines, a legacy version to maintain backwardscompatibility of existing scripts and a completely new one that is muchfaster and more powerful than its predecessor.
New CHM documentation and a wider range of 'Create New'project types directly supported by the new script engine from theeditor place a wider range of project types at your fingertips. Thereis also a new format PLUGIN system for the default editor as well asthe old one for backwards compatibility.

Now download masm.zip into some folder, and then navigate to it using Windows Explorer and double click on it.
This should bring up Winzip, and after agreeing to its conditions, click on 'Extract'. In the window this brings up, alter the 'Extract to' field displayed to 'c:masm615', and ensure that the option 'use filenames' is checked. Now click on the 'Extract' in this window, and close Winzip. This should result in the folder 'cmasm615' being created, with subfolders including 'bin' and 'programs'.

Next click on Start/settings/control panel. Then double click on 'System', select the 'Advanced' tab, and click on 'Environment Variables'. In the lower text box, select 'path', and click on the Edit button below that. Add onto the righthand end of the text which is then displayed above in 'variable value', a semicolon and then: c:masm615bin
After this, close all programs.
Now employ Start/run and type into the box: cmd
and press OK. Maximize the resulting DOS window.
Employ: cd masm615programs
This will make 'programs' the active directory. You should place all the Assembler programs that you create in this folder. The folder already contains a simple program called 'double.asm', which doubles small numbers. Compile this program using: ml double.asm
This should produce an executable called 'double.exe'.
At the command prompt, type: double
and, if everything up to this stage works, the program should ask you to enter a number less than 5.
