In the following example, the numbers 1 to 20000 would be assigned to JES3 jobs, no more than 12000 jobs could be in the JES3 complex at any given time (assuming the size of the JCT data is large enough to accommodate 12000 jobs), the multitasking facility would be off, and the maximum number of scheduler elements would default to 10. In the event of an abnormal termination or program check, a dump of MVS™ JES3-related control blocks and the JES3 region will be written to the SYSUDUMP or SYSABEND data set. The formatted JES3 control blocks will be written to the JESABEND data set:

OPTIONS,JOBNO=(1,20000,12000)
