Example:This example changes the last date the following functions have run. This permits these functions to be run again on the current day:

• Automatic backup
• Moving backup versions and backing up migrated data sets (level-1 functions)

To cause the functions to be run again, you can zero the appropriate date field and issue the SETSYS command with the AUTOBACKUPSTART parameters, specifying the appropriate times:

PATCH .BCR.+50 X'00000000' /* automatic backup           */
PATCH .BCR.+5C X'00000000' /* move backup versions and   */
                           /* back up migrated data/sets */
