About:
Ratfor (Rational Fortran) is a preprocessor that extends standard Fortran 66 with structured control flow constructs. It translates constructs like if-then-else blocks and repeat-until loops into standard Fortran code, making legacy scientific programs more readable and maintainable.
Key Features:
  • Adds structured control flow (if/else, while, repeat) to Fortran
  • Improves code readability over standard Fortran
  • Outputs portable Fortran 66 code
Use Cases:
  • Maintaining and modernizing legacy scientific computing code
  • Writing structured Fortran programs in the 1970s-80s style
Alternatives:
  • f2c – Converts Fortran to C rather than adding structure to Fortran
  • C preprocessor – Generic macro processor without Fortran-specific syntax
