which comes no surprise, as your programs indeed are in fixed source 
form (in fact the programs seem to be FORTRAN 77, but I haven't spent 
much time looking for Fortran 90 stuff).

The way it's done is correct for fixed-form source

... which are not self-contained: they try to include 'para.file'. 
Without that file there's no way I could tell you what's wrong.  But 
instead of delegating your job to me, it would probably be a simpler way 
of understanding the problem if you told us the first few error messages 
that you get if you try to compile the program (named with the correct 
extension '.f').

Cheers,

My guess is that you're source files are free-form source files despite their .f exension.  gfortran tries to guess the source-form you're using from the file extension: .f for fixed form, .f90, .f95, .f03 for free form.  If you don't want to rename your files to follow that convention and that is indeed the problem you can use the -ffree-form command line option.
