> I used to work on software that still uses Fortran from the 50's

Gnnnnnnaaaaaaaaaaaaaa!!!!!

Online conversation about Fortran is invariably domniated by people who waffle about Fortran 77, FORTRAN and bloody punch cards!

Yet modern Fortran versions are actually rather spiffing. Not to mention they can be used with the old libraries which are utterly bombproof.

There is a reason Fortran is still used for mathmatical modelling. It's simple to use, and you can really trust it.
