Fortran fixed to free source form converter

Project description

Tool to convert from FORTRAN fixed source form files to free source form. Supports OpenMP and C-preprocessor statements.

The FORTRAN fixed source format dates back to time when punched cards were used in programming. Nevertheless it is widespread in the numerical computing community. Even programs written according to the most recent Fortran 2008 standard can be written in fixed source form, although this is deprecated since Fortran 2003.

This script converts fixed source form files to the free source form, introduced with Fortran 90. In refactoring legacy Fortran codes this is a useful first step.

Some similar tools that I tried, attempt to automatically upgrade deprecated language constructs with varying success. This tool takes a more minimalistic approach and changes only the source form.
