The displayed output for a display command depends on whether the
started task source JCL is a JOB or a cataloged procedure and whether
you use the JOBNAME parameter on the START command.
- JOBNAME parameter. This parameter on the START command names the started task. (See Starting a system task from a console for additional information.)
- Membername. If you do not use the JOBNAME parameter on the START command and the source JCL is a procedure, the system automatically assigns the member name as the jobname.
- Jobname within the source JCL. If you do not use the JOBNAME parameter on the START command and the source JCL for the started task is a job, a job name is assigned based on the job name on the JOB statement.
- Identifier. If you use the identifier on the START command, you can identify the started task by both the identifier and the jobname that was assigned by the system.
If you issue a DISPLAY A,ALL command, the system will display status about all started tasks. In the following examples, the source JCL is provided and examples of the changes in the output are provided.
The following illustration has been slightly modified to improve
the readability and the column identifiers have been added as pointers;
the actual display output will not appear as in the illustration that
follows. For message details, refer to z/OS MVS System Messages, Vol 7 (IEB-IEE).
