Extended status
The extended status is also set by the automatic recovery function. Extended status E shows that an error was detected while attempting automatic recovery; extended status R means that automatic recovery has been performed and RESTART was requested.
If no RECOVER statement is invoked for the error, the extended status field is left blank.
If RESTART=N is specified, the extended status field is set to R to show that recovery has taken place.
If an error is detected while processing a RECOVER statement, the extended status field is set to E.
