Yes, things have changed a lot since the FORTRAN days :-) . I can suggest one Mathematica package that I have used when teaching and undergraduate course in OR --- DynPac. It was developed by Professor Al Clark at Rochester University --- http://www.me.rochester.edu/~clark/
This is a very nice package and believe that it might fit your needs.
