Converting Fortran IV to 77

I am looking for a utility to convert fortran IV code to a more structured sort of fortran like fortran 77 or later. I am trying to understand what exactly the code does and all those "goto" and calculated "if" statements don't help. Thanks.

All already mentioned aside, in the end it always comes down to a bit of hard labour :) And that's where SciTools Understand shines.

There is also PlusFort, which can do comprehensive restructuring -- see the examples at http://www.polyhedron.com/spag0html. There is a reduced capability version that is free for certain uses: http://www.polyhedron.com/pflinux0html

There's a section of the FORTRAN FAQ on this (search for "Code re-structurers and converters")

TIDY looks like it will do some of the work for you. Unfortunately not including the calculated-if and goto

Web page last updated more than 10 years ago!

A commercial product is here, but costs ~$500 for 5000 lines of conversion.

Courses on how to do this manually can be found here
