JES2,JES3 and JES statements:
Under JES2 and JES3, a job stream can also include JES2 or JES3 control statements that influence the way the Job Entry Subsystem processes your job.
In old projects, you may come across JES control statements in older job streams, and occasionally, they provide for a function that isn’t available in standard JCL.
