This defines a batch initiator or printer SEP that will be a permanent feature of the enterprise server, starting up whenever the enterprise server is started. If you want to start a batch initiator or printer SEP "on the fly" while the enterprise server is running, to run waiting jobs immediately, see To start a batch initiator or printer immediately.
In Class, type the list of job classes you want this initiator to run, or this printer to print; for example, ABC. The JOB CLASS of a JCL jobstream must match the class of a batch initiator SEP in order for the SEP to run the job. The MSGCLASS or SYSOUT class must match the class of a batch printer SEP in order for the SEP to print the output.
