The Deliver RMORPT REPORT 5 lists Active Reports and Bundles.
Active reports (and active bundles) are displayed as are selected from the Deliver Primary panel (A R - for Active Reports, A B - for Active Bundles).
The Deliver checkpoint file contains information about Active Reports and Bundles.
The entries in the checkpoint file reflect multiple things:
. . The reports that were activated by running Deliver program RMORAP.
. . Entries created by use of Deliver RMOPARM AUTOACT=YES.
. . Entries created by multiple runs of a job.
. . The entries are dynamic and are designed to reflect the active reports and bundles at a given time.
