The name MASM has earlier usage as the Unisys Meta Assembler but since about 1990 when Microsoft introduce MASM version 6.0 the name MASM has normally been associated with the Microsoft Macro Assembler. MASM is a programming tool with a very long history and has been in constant development since it earliest version in 1981. For MASM-related samples, download the Compiler samples from Visual C Samples and Related Documentation for Visual Studio 2010. The following example demonstrates the use of the.MODEL directive. Example; file simple.asm; For x86 (32-bit), assemble with debug information:; ml -c -Zi simple.asm; For x64 (64-bit), assemble with debug information:; ml64 -c -DX64 -Zi simple.asm.

Install MASM (Assembly language) on Windows 7

The good old legacy MASM 6.11 (DOS) is a 16-bit version, that unfortunately only works on Windows XP and earlier versions of Windows.

However there is always some way to emulate the older softwares and run them without any compatibility issues. Since it is a DOS based application, we need to emulate the DOS environment to make it work.

We are going to use a free tool named DOSBox. It's a free DOS emulator that can run old DOS applications. Let's begin.

Step 1:

Download the DOSBox free emulator from here, and install it.

Step 2:

Download the MASM 8086 Assembler from here, and extract it.

Step 3:

Rename the 8086 folder to MASM. You can skip this step It's not necessary to rename if you can remember the folder name.

Step 4:

Copy or Cut the MASM folder.

Step 5:

Go to your desired drive (C: drive is recommended), and paste the folder there.

Step 6:

Go back to the Desktop and double-click on the DOSBox to run.

Step 7:

Now before using MASM you need to mount the working directory.
type the command below to mount the drive:

Step 8:

Change the drive letter to your desired drive where you have MASM installed. to change the drive from Z to C, type the command shown below:

Step 9:

To open the DOS Editor type:

Step 10:

Type your program source code, and save it by going to File -> Save or press Alt + F to open the File menu.

Step 11:

Save it in C:MASM (default directory) with the .asm extension in the end.

Step 12:

Exit from the DOS Editor to go back to the Command Prompt.
In the Command Prompt type this command to assemble the program.

Step 13:

Then just simply link the object by typing

and execute/Run it by typing just the program name:

That's how you can use old DOS applications on a recent version of Windows. It all other commands are same as old MASM. Please drop any queries below in the comments.

The Microsoft Macro Assembler (MASM) is an x86assembler 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. It is instead supplied with various Microsoft SDKs and C compilers. Recent versions of MASM are included with Microsoft Visual Studio.

History[edit]

The earliest versions of MASM date back to 1981.^[1] They were sold either as the generic 'Microsoft Macro Assembler' for all x86 machines or as the OEM version specifically for IBM PCs. By Version 4.0, the IBM release was dropped. Up to Version 3.0, MASM was also bundled with a smaller companion assembler, ASM.EXE. This was intended for PCs with only 64k of memory and lacked some features of the full MASM, such as the ability to use code macros.

MS-DOS versions up to 4.x included Microsoft's LINK utility, which was designed to convert intermediate OBJ files generated by MASM and other compilers; however, as users who did not program had no use of the utility, it was moved to their compiler packages.

Version 4.0 added support for 286 instructions and also shorthand mnemonics for segment descriptors (.code, .data, etc.). Version 5.0 supported 386 instructions, but it could still only generate real mode executables.

Through version 5.0, MASM was available as an MS-DOS application only. Versions 5.1 and 6.0 were available as both MS-DOS and OS/2 applications.^[2]

X64 Assembly

Version 6.0, released in 1992, added parameter passing with 'invoke' and some other high level-like constructs, in addition to the already existing high level-like records, among other things. By the end of the year, version 6.1A updated the memory management^{[how?][clarification needed]} to be compatible with code produced by Visual C++. In 1993 full support for protected mode 32-bit applications and the Pentium instruction set was added. The MASM binary at that time was shipped as a 'bi-modal' DOS-extended binary (using the Phar Lap TNT DOS extender).

Through version 5.0, MASM was available as an MS-DOS application only. Versions 5.1 and 6.0 were available as both MS-DOS and OS/2 applications.^[2]

X64 Assembly

Version 6.0, released in 1992, added parameter passing with 'invoke' and some other high level-like constructs, in addition to the already existing high level-like records, among other things. By the end of the year, version 6.1A updated the memory management^{[how?][clarification needed]} to be compatible with code produced by Visual C++. In 1993 full support for protected mode 32-bit applications and the Pentium instruction set was added. The MASM binary at that time was shipped as a 'bi-modal' DOS-extended binary (using the Phar Lap TNT DOS extender).

Versions 6.12 to 6.14 were implemented as patches for version 6.11. These patches changed the type of the binary to native PE format. Version 6.11 is the last version of MASM that will run under MS-DOS.

By the end of 1997, MASM fully supported Windows 95 and included some AMD-specific instructions.^[3]

In 1999, Intel released macros for SIMD and MMX instructions, which were shortly thereafter supported natively by MASM. With the 6.15 release in 2000, Microsoft discontinued support for MASM as a separate product, instead subsuming it into the Visual Studio toolset. Though it was still compatible with Windows 98, current versions of Visual Studio were not.^[3] Support for 64-bit processors was not added until the release of Visual Studio 2005, with MASM 8.0.

After 25 June 2015, there are at least three different MASMs with the version number 14.00.23026. In Microsoft Visual Studio 2015 Enterprise Edition, there is one 'amd64_x86' ml and two ml64s, 'x86_amd64' and 'amd64'. They run on different platforms targeting different platforms:

• amd64_x86: generates 64-bit code, runs in a Windows 32-bit environment
• x86_amd64: generates 32-bit code, runs in a Windows 64-bit environment
• amd64: generates 64-bit code, runs in a Windows 64-bit environment

Object module formats supported by MASM[edit]

Early versions of MASM generated object modules using the OMF format, which was used to create binaries for MS-DOS or OS/2.

Since version 6.1, MASM is able to produce object modules in the Portable Executable^[4][5] (PE/COFF) format. PE/COFF is compatible with recent Microsoft C compilers, and object modules produced by either MASM or the C compiler can be routinely intermixed and linked into Win32 and Win64 binaries.

Assemblers compatible with MASM[edit]

Some other assemblers can assemble most code written for MASM, with the exception of more complex macros.

• Turbo Assembler (TASM) developed by Borland, later owned by Embarcadero, last updated in 2002, but still supplied with C++Builder and RAD Studio.
• JWASM Macro Assembler, licensed under the Sybase Open Watcom EULA.
• Pelle's Macro Assembler, a component of the Pelles C development environment.
• UASM is a free MASM-compatible assembler based on JWasm.

Mixed language programming support[edit]

Documentation for 1987's version 5.1 included support for 'Microsoft BASIC, C, FORTRAN, Pascal.'^[6]

Licensing issues[edit]

Using MASM for operating system development is not prohibited in the license agreement although you may sometimes hear that. This is because people often confuse the MASM and MASM32 licenses; they are two unrelated projects.
