About JCL

Furthermore, in the batch mode, applications submitted to the operating system as a job through a JCL. Therefore, the Operating System uses Job Entry System (JES) to receive the tasks into the Operating System and also to schedule the tasks for processing and to control the output. Make a note that the Job processing for the schedule, goes through a series of steps as offered below:

• Job Submission
• The Job Conversion
• Job Queuing
• And Job Execution
