Sequence=(n,m)
    Nosequence

    Specifies that the journals with sequence numbers from n to m
    inclusive are to be backed up. The values n and m are interpreted
    or interpolated as follows:

    o  If Sequence = (33, 35) is specified, then the .aij files with
       sequence numbers 33, 34, and 35 are backed up.

    o  If Sequence = (53, 53) is specified, then the .aij file with
       sequence number 53 is backed up.

    o  If Sequence = (53) is specified, then the .aij files with
       sequence numbers 53 and lower are backed up, if they have
       not been backed up already. For example, if .aij files with
       sequence numbers 51, 52, and 53 have not been backed up, then
       Sequence = (53) results in these three .aij files being backed
       up.

    o  If Sequence = (55, 53) is specified, then .aij files with
       sequence numbers 53, 54, and 55 are backed up.

    o  If the Sequence qualifier is specified without a value list,
       both n and m are set to the sequence number of the next
       journal that needs to be backed up.

    The default is the Nosequence qualifier. When the default is
    accepted, the backup operation starts with the next journal that
    needs to be backed up and stops when the termination condition
    you have specified is reached.

    The following qualifiers cannot be used or have no effect when
    used with the Sequence qualifier:

       Continuous
       Format=New_Tape
       Interval
       Quiet_Point
       Threshold
       Until

    Furthermore, fixed-size after-image journals must be in use when
    this qualifier is specified.
