Statement Summary

Table 1. SELECT Summary
Variable	Value
Required/Optional Statement	Optional
Statement Default	JES3 assigns the following default select mode to any main whose associated MAINPROC statement does not specify the SELECT parameter: `SELECT,NAME=JS3BATCH,CHOICE=FFIT,LSTOR=12000, SDEPTH=255,MAGEL=14,MAGER=0,SAGEL=14,SAGER=0, SBAR=16,INCL=14,INCR=1`
Placement in Initialization Stream	This statement must follow the ENDJSAM statement.
Coding Considerations	The SELECT parameter specified on a MAINPROC statement as the initial select mode must match the NAME parameter on a SELECT statement. The CLASS parameter on the SELECT statement must match the NAME parameter on one or more CLASS statements. The GROUP parameter on the SELECT statement must match the NAME parameter on a GROUP statement. The LSTOR parameter is ignored when scheduling jobs in WLM-managed groups.
Security Usage	None
Performance Considerations	None. See z/OS JES3 Initialization and Tuning Guide for additional information about how the SELECT, CLASS, and GROUP initialization statements affect the processing of WLM-managed jobs and JES3-managed jobs.
Initialization Stream Overrides	None.
Restart or Command Modification	Hot start with refresh for all parameters. You can use the `*MODIFY,G,main,S` command to override some SELECT statement parameters.
