A QUERY command was issued with the BACKUP parameter. The number of days in the automatic dump cycle is ndays. The dump cycle definition, Y for days on which automatic full volume dump is to run and N for days it is not to run, is given by string.

The migration cycle day is a 24-hour period beginning at the early start time as specified in the SETSYS AUTODUMPSTART command, not a 24-hour calendar day beginning at midnight. Today is the nth day in the cycle. The first day in the cycle is yy/mm/dd. Note that if the QUERY BACKUP command is issued prior to the early start time, the nth day represents the 24-hour period that began on the prior calendar day at the early start time. For example, if the early start time is 1900 with a 7-day cycle starting on Sunday, the day in the cycle will be 1 until 1900 on Monday. After 1900, it will be 2 when a QUERY BACKUP command is issued. When the dump cycle has not been defined, *NONE* is the insert for the day.

If today is a Y day in the dump cycle, an explanation is provided for eligibility to start or restart automatic full volume dump. If today is an N day in the dump cycle, an explanation is provided for eligibility to start or restart dump-level functions.
