The Microsoft Fortan Powerstation 1 is a F77 with F90 like extensions compiler embedded in Visual Studio 97 but targeted for 32bit DOS application (Pharlap Dos extender) and QuickWin applications.
The compiler doesn't run under Windows NT/2000/XP.
The FMK (project) file is a text file structured like a "make" file. You can find in it all the sources files, compiler and linker options.
I think it will be easier to upgrade to IVF.
