QUE entry for work element queued to PAB
- Entry:
- QUE
- VIT option:
- PSS
- Event:
- Work element queued to PAB
- VIT processing module:
- ISTRACPS
- Control is returned to:
- ISTAPCTQ
This trace record shows a work element queued to a PAB
to allow another VTAM® routine
to do further processing with the work element. This entry may be
followed shortly by a DSP entry, representing the PSS dispatch of
this PAB. However, if the PAB is already running, it might not be
dispatched again. In this case, no DSP entry follows the TPQUE.
