FORTRAN to Ada conversion

FORTRAN to Ada conversion

[Paul Storm]

I am starting a project to convert an existing FORTRAN program to Ada. 
I do NOT want to call the FORTRAN program from Ada.  I want to convert
the program itself.  The only references I have found in the RM is on
how to interface to a FORTRAN program.

Anyone got some pointer on program conversion from FORTRAN to Ada?  I'm
wondering if there is a conversion program/parser out there somewhere.

The only thing I've seen lately is a post from Gautier:

The DMS Software Reengineering Toolkit is generalized compiler technology
used to automate custom analyses/ source enhancements/ translations of large
scale software systems.   DMS parses many langauges, automatically
builds compiler data structures (ASTs), applies analyses and
source-to-source
transformations, and prettyprints the results.

DMS presently knows both Fortran and Ada, but has not yet been
given a translation map between the two.    This isn't a small effort to do,
but it is much smaller than attempting to build such a translator from
scratch
or from ad hoc pieces.  So it makes sense if you have a large source
base to translate, or you want to ensure a reliable translation.

See http://www.semdesigns.com/Products/DMS/DMSToolkit.html.
There are some slides there showing how DMS can be used for porting.
