- You can use the $JCTX macro extension service to add,
expand, locate, and delete extensions to the job control table ($JCT)
control block from this exit. For example, you can use these extensions
to store job-related information. Extensions that are added can be
SPOOLed extensions that are available to all exits that read the JCT
or local extension that are available only to input processing exits
(2, 3, 4, and 20) and the $QMOD exit (51). The size of SPOOLed extensions
is based on the SPOOL buffer size and is less than 3K. You can have
up to 8K of local extension regardless of SPOOL buffer size.
- If you need to change the scheduling environment, use the JCTSCHEN
field in the JCT.
