EPR - Event data set positions
Name : DCLEPR
Function:
This segment declares the scheduler event data set position record. The third record on the first track of
the checkpoint data set is always the EPR for the scheduler host system. The following records are EPR
records for remote nodes. The order of the EPR records is the same as the order of the scheduler node
names in the NNN record.
