Statement Default	`SETPARAM,ADDRSORT=YES,ALLOCATE=AUTO, DAFETCH=97, DEFERCT=NO, DSN=0,FETCH=YES,MDSLOG=97, REMOUNT=1,TAFETCH=(97,97),ALWIO=10, MAXIO=25,PRJESMSG=NONE,SMSSETUP=YES MTJESMSG=(ALLOC,BREAKDWN)` Note: For the DAFETCH, MDSLOG and TAFETCH parameters, the default of 97 is the routing code equivalent of JES3 Dest Class S1.
Placement in Initialization Stream	This statement must follow the ENDJSAM statement.
Coding Considerations	If SETUP=NONE is specified on the STANDARDS statement to indicate no MDS, then SETPARAM is ignored and all devices are allocated, mounted, and deallocated by MVS™.
Security Usage	None
Performance Considerations	None
Initialization Stream Overrides	The SETPARAM statement is overridden if SETUP=NONE is specified on the STANDARDS statement; all devices are allocated, mounted, and deallocated by MVS instead of MDS.
Restart or Command Modification	Warm start or cold start for the SMSSETUP parameter. Cold start, warm start, or hot start with refresh for all other parameters. Use the `*MODIFY,S` command to change the ALLOCATE, ALWIO, and DEFERCT parameters.
