The Spooler and Batch Jobs

The method that the spooler uses to determine if a job becomes a normal job, the first

job in a batch job, or a job to be linked to an existing batch job is shown in Figure 1-7.

If a job is part of a batch job, you cannot alter the key attributes unless you use the

Peruse UNLINK command or the UNLINK option of the Spoolcom BATCH command to

unlink the job from the batch job.

Other job attributes have no effect on whether the job is linked to a batch job. Some

attributes might have no meaning for a job that is part of a batch job. For example,

if every job within a batch job contains a different report name, only the report name

associated with the first job in the batch job is printed on the header pages for that

batch job. Attributes that have meaning only to the first job in a batch job are the report

name, batch name, and selection priority.
