I am looking for software that will convert RATFOR source code to FORTRAN 77
or 90 source code.  There are specific reasons for converting to FORTRAN
instead of C or someone's other favorite language so there is no need to 
use bandwidth to discuss the "right" thing to convert the RATFOR to.

The RATFOR that I need to convert consists of about 250,000 lines of source
and also includes a very capable macro substitution capability.  I have
plans for handling the macro substitutions but suggestions are welcome.
The RATFOR preprocessor being used generates FORTRAN IV source with the
usual implementation of looping via IFs and GOTOs which causes compiler
optimizations to be minimal.

The RATFOR software currently runs under DEC/VMS and I would like to move
along a migration path of RATFOR VMS --> FORTRAN VMS --> FORTRAN Unix.
Any and all suggestions or experiences related to this effort will be
appreciated.

Thanks in advance.
