A JES job is an entity under control of the JES job entry system (a.k.a. spooler) on an MVS host, consisting of job attribute information and a set of JES job data sets. This includes an MVS job stream, any SYSIN-type data sets provided with the job stream, and any SYSOUT-type data sets created if the job stream has been processed.
For parameter input, a JES job is identified by either its job name or its job number or by both its job name and job number. If both are provided, they must be separated by a slash (/).
For a job of name CICSTEST and number 1287, the following are all valid ways to identify the job:
cicstest
cicstest/1287
1287
