A CICS application can use a CA Spool file for holding data, rather than writing to a transient data queue.
An online transaction can create a spool file of input data for a waiting batch processing program. When the spool file is complete, the batch program is notified and processes the data and creates a spool file for online display. After processing, the batch program deletes the input spool file, or allows it to be deleted automatically after an installation-specified retention period.
