DF6.1 is Digital FORTRAN 6.1 ?

A possible solution would be to write any VC6 and DF6.1 code to generate
some DLLs (black boxes) and to use these DLLs from Python by using
ctypes, to build your applications. All the CPU intensive code should be
in DLLs and the high level stuff (GUI, presentation, application logic,
...) could be in python. (GUI with wnd or venster for example).
