Abend Status

Before entering the main loop, DK1TDRVC issues a CS command to change TBLBASE Abend Status to N, turning off abend processing. This setting causes TBLBASE to return error codes instead of abending. DK1TDRVC incorporates the returned codes into its report of command results and then accepts the next command as usual. Users may, of course, re-enable abends in TBLBASE with another CS command.
