Folks, i noticed 3 similar and minor typos in the MPI 3.1 standard 1) MPI_COMM_SET_ATTR page 270 line 43 reads "INOUT comm ..." but should be "IN comm ..." 2) MPI_WIN_SET_ATTR page 274 line 33 reads "INOUT win ..." but should be "IN win ..." 3) MPI_TYPE_SET_ATTR page 278 line 3 reads "INOUT datatype ..." but should be "IN datatype ..." note Fortran 2008 correctly reads "INTENT(IN)" Cheers, Gilles
