Pre-Open Processing (TSIDASS)
Chapter 8. BIM-EPIC Utilities 8-5
OUTPUT specifies that the dataset was last opened as output.
EXT specifies the sequence number of the extent to be re-opened. This is only necessary for
disk datasets, and only if the dataset is to be opened at an extent other than the primary extent.
This number will be equal to the number of BIM-EPIC EP053 messages that were issued for
the dataset prior to the checkpoint from which the program will be restarted.
