Warning
JES3 users should be aware of a limitation within JES3 that does not allow concurrent tasks to share SYSOUT data sets. This limitation means that you cannot use additional sort routine reporting DDs (other than UTPRINT) if they are defined as JES3 SYSOUT data sets and when the utility is multitasking its sort activity. If you attempt to use an unsupported DD, you risk S1FB abends when concurrent sort tasks are running.
