ASM - Assembly Language Source Code File

What is a ASM file

Assembly language is a quite low-level programming language. Code written in this language is commonly saved using the ASM file extension. These files contain the code of programs that can be translated into machine language for the programs to be executed.

ASM files contain source code, saved in a plain text format. Due to this, they can be opened, edited and produced using a basic text editor. In order to run the program coded using the Assembly language, however, an assembler program is needed. The assembly language inside the ASM code very strongly resembles the actual instructions of the device's code.

Here's a small, but not exhaustive list of programs that can open ASM documents:

  • File Viewer Plus (Windows)
  • GNU Emacs (Linux)
  • gVim (Windows)
  • MacroMates TextMate (Mac)
  • MacVim (Mac)
  • Microsoft Notepad (Windows)
  • Pico (Linux)
  • Vim (Linux)
  • Any Text Editor
