## What it is
Visual MASM is a free IDE for the Microsoft Macro Assembler (MASM) that lets users write, assemble, and debug 16/32/64-bit Windows and 16-bit MS-DOS assembly programs. It includes a code editor, form designer, and project management, and can download MASM32 or the Microsoft Platform SDK to get started.

## Use cases
- write x86 assembly programs on Windows
- learn assembly language programming with MASM
- build 16-bit MS-DOS applications in assembly
- assemble 32-bit and 64-bit Windows executables with MASM
- visual form designer for assembly GUI apps
- set up a MASM development environment quickly

## When to choose
- you want a dedicated Windows IDE for Microsoft Macro Assembler
- you are learning x86 assembly and want an all-in-one editor, assembler, and debugger setup
- you need to build 16-bit DOS or 32/64-bit Windows assembly programs

## When to avoid
- you develop on Linux or macOS - it is Windows-only
- you need an actively maintained tool with recent updates and support
- you use a different assembler such as NASM or GAS

## Facets
- artifact type: application
