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:  http://hpcf.nersc.gov/software/ibm/c_and_f.html
For C++ two key references are: http://www-zeus.desy.de/~burow/cfortran/   and http://scipp.ucsc.edu/groups/silicon/ATLAS/DaqLab/soft/usingFor/
