The internal reader facility can be used to request job notification for a job that is being submitted:

• Job notification is requested by defining the SYS_JOB_NOTIFY symbol before submitting a job using the internal reader.
• When the job is no longer eligible for execution, JES sends job completion notification by ENF 78. Refer to z/OS MVS Programming: Authorized Assembler Services Reference EDT-IXG for ENF 78 information.
• ENF 78 includes job identification information and the value of the SYS_JOB_NOTIFY symbol.
• Applications can use job notification to track submitted jobs.
