The following JES control statements affect the way in which the internal reader handles the input stream it receives:

• /*EOF - ends the current job in the data set and makes it eligible for immediate processing.
• /*DEL - deletes the job in the data set and schedules it for immediate SYSOUT processing. This statement deletes the current job in the job stream. If there is no job in the data set, this statement has no effect. The SYSOUT consists of any JCL submitted, followed by a message indicating that the job was deleted before execution.
• /*SCAN - causes the job to be scanned for JCL errors, but not executed. (The same processing occurs if TYPRUN=SCAN appears on the JOB statement.)
• /*PURGE - deletes the job in the data set and schedules it for purge processing. If no job is in the data set, this statement deletes the previous job in the job stream. No output is produced for this job. This is for JES2 only because JES3 does not recognize /*PURGE as a control statement.
