Supported file extensions

The extensions f90, .f95, .f03, and .f08 are used for modern, free-form source code conforming to the Fortran 90, Fortran 95, Fortran 2003, and Fortran 2008 standards, respectively.

The extensions .F90, .F95, .F03, and .F08 are used for modern, free-form source code that require preprocessing, and conform to the Fortran 90, Fortran 95, Fortran 2003, and Fortran 2008 standards, respectively.

The .f and .for extensions are typically used for older, fixed-form code such as FORTRAN77.

The file extensions that are compatible with Arm® Fortran Compiler are:
