I am trying to modify a model which is written as a mixed language program in Fortran and C and the main program was FORTRAN. I have Microsoft Visual C++ 6.0 and Visual FORTRAN 5.0A. Do I have to buy FORTRAN 6.0 to call C? Thanks. Jay

You don't have to. Most CVF6 functionality in this regard was available in CVF5. There are lots of reasons for upgrade, and I'd recommend your to do so, but if it's one-time project with limited budget, you can get by with what you have. Of course, you won't be able to use common VS IDE for building (although I think debugging is possible in one or another VS). At least, upgrade to 5.0D -- this solves some nasty bugs in 5.0A.
