What is a .BAS file?
BAS files store source code written in BASIC, a programming language originally designed to make programming easier to learn. The code can define variables, perform calculations, display information, accept user input, and control a program's execution. Many BASIC dialects exist, including those used by older home computers, educational programming environments, and Microsoft development tools, so the exact syntax and features depend on the language version.
You may come across BAS files while exploring a legacy software project, following a programming tutorial, or working with applications developed in Visual Basic or another BASIC environment. They are also found in archived programs for older computers, sample projects, and source code collections. Developers typically open them in a compatible programming editor or IDE to review, modify, and compile the code as needed. File Viewer Plus can open, edit, and save BAS files, helping you examine or update their source code.
