Hello

we are juste beginner in fortran but familiar with MPI and C

we would like to know if it was true that MPI_function can only be
called from Main 
program and not from SubRoutines

We have problems with the re-declaration of "integer
status(MPI_STATUS_SIZE)"
the SGI fortran Compiler answers "
 line 74: error(2194): "MPI_STATUS_SIZE", used as array bound, is
          not a dummy argument or in COMMON
        integer status(MPI_STATUS_SIZE)"

after a quick look at "mpif.h" we try to affect "integer status(6)" but
the answer is
even worse : "
ld64: WARNING 84: /usr/lib64/mips4/libmpi.so is not used for resolving
any symbol.
ld64: ERROR 33: Unresolved text symbol "mpi_init_" -- 1st referenced by

this little problem block us to finish our project
Thank you
