Files that contain the .bas file extension are most commonly associated with program source code that has been written in the BASIC programming language.

BASIC is a programming language that was created in the 1960s and the name is an acronym for Beginner's All-Purpose Symbolic Instruction Code. When a program source code file is created using the BASIC language, it is saved with the .bas file extension.

The Microsoft QuickBASIC software program is an application that allows users to create programs using the BASIC language in an easy-to-use software application. These BASIC files are also saved with the .bas file suffix.
