Example of the THRESHLD parameter

//STEPA  EXEC   PGM=RPTWRT
//SYSDS3 OUTPUT DEFAULT=YES,THRESHLD=10000
//RPT1   DD     SYSOUT=A,COPIES=10
//RPT2   DD     SYSOUT=A,COPIES=2
//RPT3   DD     SYSOUT=A,COPIES=5

In this example, the report data sets, RPT1, RPT2, and RPT3, are processed in sysout class A. All three DD statements implicitly reference the step-level default OUTPUT JCL statement SYSDS3; therefore, the THRESHLD value specified in the OUTPUT JCL statement applies to the three reports combined. JES3 is to print the following:

Copies	Data Set	Records in Data Set	Total Records
10	RPT1	1000	10000
2	RPT2	2000	4000
5	RPT3	500	2500

			Total 16500

Because the total exceeds the THRESHLD limit, JES3 divides the sysout data sets into two units of work. RPT1 is printed as one unit, and the other two data sets are printed together as another unit. If the THRESHLD limit had been 20000, all three data sets would have been printed as one unit of work.
