If I recall correctly the OMPI build does not generate a full Fortran <--> C mapping of all types for all functions. Was the reason that the resulting library has too many permutations and symbols to test, build and link to. While not a co-array related comment is there a way to generate the necessary bindings on the fly and facilitate stronger type checking and perhaps open the door for richer optimizations from the compiler folk. http://www.open-mpi.org/papers/euro-pvmmpi-2005-fortran/euro-pvm-mpi-2005-fortran.pdf Will Fortran 2008 revisit some of these issues in a problematic way? Or is this such old news that folk just live with it? Later, mitch
