              - name of file to open (string)

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.  'ierr' is an integer and  has  the  same
       meaning as the return value of 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.
