Converting old Fortran programs to PGI Fortran

I have some FORTRAN programs that I wrote many years ago, I think using a compiler that was some version of the visual series (as I recall it was owned by different companies at different times).
To use Windows I/O I included the “USE DFLIB” specification. I want to convert my programs to PGI under Microsoft Visual Studio and don’t know how to access (or use since I haven’t been able to find appropriate references) the kinds of routines I used under DFLIB.
Anyone providing relevant information would be appreciated.

Hi JimInTampa,

You can find documentation on which DFLIB routines we support on Windows here:

Hope this helps,

Thanks Mat, I think I’ll find that helpful.
