What is an F77 file?

An F77 file contains source code written in the Fortran 77 (F77) programming language. It is used to compile a Fortran 77 program using the language's compiler, which is also named F77.

More Information

F77 is a programming language often used for performing scientific and numerical computations. It is a variant of the original Fortran programming language. The original Fortran language was released in 1957; F77 was released in 1977. Notably, F77 includes support for structured programming and character-based data, while the original Fortran language did not.

While most developers save their F77 source code in .FOR or .F files, so they are easily recognizable as Fortran-based source code files, some save their code in F77 files. This denotes that the files contain F77 source code specifically, and not code written using some other Fortran variant.

How to open an F77 file

You can open and edit an F77 file in any text or source code editor. Source code editors, such as Microsoft Visual Studio Code (cross-platform) and GitHub Atom (cross-platform), contain helpful tools that make reading and editing F77 files easier.
