A .CBL file is a COBOL Source Code File, created by N/A.

Open with TinyCOBOL. Available for Linux, Windows, and Mac.

What is a .CBL file?

The file extension .CBL refers to a COBOL Source Code File. COBOL, which stands for COmmon Business-Oriented Language, is one of the oldest programming languages that is still used today. It is primarily used for creating software applications in areas such as business, finance, and administrative systems.

A .CBL file contains the actual code written in the COBOL language. However, to turn this code into a running program, it needs to be processed by a special program called a COBOL compiler. This compiler translates the COBOL code into a form that computers can understand and execute.

There are several programs that can open and work with .CBL files. Some of these include: - TinyCOBOL: A lightweight COBOL compiler. - GnuCOBOL: An open-source COBOL compiler. - File Viewer Plus: A versatile file viewer that can open .CBL files, available from the Microsoft Store. - IBM COBOL: A compiler provided by IBM, tailored for their systems. - Alchemy Solutions NetCOBOL: Another compiler that allows COBOL programs to run on various platforms.

It's important to note that there are different versions of the COBOL language, such as COBOL-68, COBOL-74, COBOL-85, and COBOL 2002. Each version has its own features and capabilities. Therefore, when working with .CBL files, you should ensure that your text editor and compiler are compatible with the specific version of COBOL that the code is written in. This compatibility is crucial for the successful compilation and execution of the COBOL program.
