Most environments I know, which include DG AOS/VS, VMS and UNIX have compatible
compilers, meaning you can interleave objects originating from different
languages to create your load module.

Of course, when reading a FORTRAN routine from C, it is important to remember
that FORTRAN arguments are passed by reference, thus pointers have to be
passed.  In case of character type, I am not sure there is a simple C
equivalent, and maybe some sort of simulation through the use of "struct" is
necessary.

The loading of the FORTRAN library indeed poses a problem.  I don't know if it
is setteled in any system.
