NOTES FOR FORTRAN

       All  MPI  routines  in Fortran (except for 'MPI_WTIME' and 'MPI_WTICK')
       have an additional argument 'ierr' at the end  of  the  argument  list.
       the  routine  in  C.   In Fortran, MPI routines are subroutines and are
       invoked with the 'call' statement.

       All MPI objects (e.g., 'MPI_Datatype', 'MPI_Comm', 'MPI_File')  are  of
       type 'INTEGER' in Fortran.
