FORTRAN to C

The industry leader for over twenty-five years, gmFortran (formerly known as promulaFORTRAN ) has been proven in hundreds of ambitious Fortran-to-C translation efforts. This tool can be used to produce custom C translations that are both correct (functionally equivalent to the original FORTRAN) and maintainable (i.e., of high C-code quality, subject to the client's C programming standards or custom preferences).
