With INMIDAS you start each session of MIDAS. With SETMIDAS you once set up the symbol MIDOPTION and the logical name MID_WORK which are used in each subsequent INMIDAS.
If MIDOPTION is set to NOPARALLEL, all intermediate MIDAS working files in the MIDAS startup directory are deleted when starting MIDAS via INMIDAS.
If MIDOPTION is set to PARALLEL, no intermediate files are deleted. So, the PARALLEL option is necessary if you want to run several sessions of MIDAS simultaneously.
