I would like to know how I can combine Fortran and "c" programs.
If you know of a good book that gives examples could you send me the name.
If you have an example, could you send me it.
I am using a SUN with BSD 4.2 Unix.
Thank you in advance.

It depends on the compilers you are using for fortran and C. On a HP-9000 the process is totally invisible, i.e you just call the fortran function from you C program: external some_fortran_function; . . . some_fortran_function(arguments) And the same if you call a c function from a fortran program. Just remember that all arguments to a fortran function called from C should be pointers, and that all argument declarations in a c function called from fortran should be pointers. (The only limitation are function pointers, which you cannot send easily. Structures can also be a mess). Compile each object with the corresponding compiler, and then link the objects together using your favorite linker (Use for example the compiler to which the main program corresponds). For other systems, you may have to build a so-called jacket routine, which translates the function name in C to the corresponding function name in fortran and inversely. Check your compilers system manual. -Kjartan --------------------------------------------------------------------------- Kjartan Pierre Emilsson Science Institute of the University of Iceland Dunhaga 3 Reykjavik ICELAND e-mail: pierre@krafla.rhi.hi.is
