Event reader (ER)
The event reader (ER) subtask provides support for reading event records from an event data set.
Subtask initialization consists of building control blocks for the ER subtask, reading and processing the parameter library member, and opening the input event data set.
Subtask mainline
logic provides service for the following events:
- Timer expiration. Process the event data set.
- Subtask stop request. Return to caller.
- Reading suspend request. Start/stop reading from the event data set.
