60	!> Handling of the different kinds of messages.
61	!> Meaning of formal parameters:
62	!> requested_action: 0 - continue, 1 - abort by stop, 2 - abort by mpi_abort
63	!> 3 - abort by mpi_abort using MPI_COMM_WORLD
64	!> message_level: 0 - informative, 1 - warning, 2 - error
65	!> output_on_pe: -1 - all, else - output on specified PE
66	!> file_id: 6 - stdout (*)
67	!> flush_file: 0 - no action, 1 - flush the respective output buffer
