Task Charts

The following charts list the job control tasks, which are described in the z/OS MVS JCL User's Guide, in four groups:

Entering jobs in Table 1
Processing jobs in Table 2
Requesting data set resources in Table 3
Requesting sysout data set resources in Table 4

For each task, the charts list the parameters and statements that can be used to perform it. In many cases, the same task can be performed using different parameters on different statements. Where a parameter can appear on both a JOB and EXEC statement, it applies to the entire job when coded on the JOB statement but only to a step when coded on an EXEC statement.

The system is designed to enable users to perform many types of job control in many ways. To allow this flexibility, only two job entry tasks are required:

Identification: The job must be identified in the jobname field of a JOB statement.
Execution: The program or procedure to be executed must be named in a PGM or PROC parameter on an EXEC statement.

Therefore, the following statements are the minimum needed to perform a job control task:

   //jobname  JOB
   //         EXEC  {PGM=program-name   }
                    {PROC=procedure-name}
                    {procedure-name}
