Mixed Language Programming - Fortran Calling C and C++ Subprograms

Mixing C with Fortran subverts use of debugging compilers like Salford FTN95 FTN77 and Lahey LF95. Thus one is more wide open for subtle semantic errors like a subscript out of range, invalid subprogram argument/parameter matching, undefined (mistyped) variable, etc. In a certain sense mixing languages detracts from both portability and integrity of application.

If you still have or want to write a C subprogram callable by Fortran I suggest that you see  an actual working example:
For C++ two key references are:   and

If you are working with C++ and Fortran see:   Chasm - C++ Fortran 99 Interoperability Tools:

Free Fortran Software

This software is made available as a service of the Fortran Market and others. Please take anything you think you will find useful.

There should be a version of the I/O module and the kind parameter module for each Fortran 90 implementation. Vendors: please supply a version for your implementation!
