                  THE DEVICE IT CURRENTLY RESIDES ON -- THIS WILL BE CONSIDERED WHEN CALCULATING
                  THE EFFECT OF THE TARGET DEVICE ('3490E')

    #1---->  *  - THE VOLUMES ASSOCIATED WITH THIS DATA SET NO LONGER EXIST, AS THEY HAVE BEEN RETURNED
                  TO SCRATCH FOR REUSE. THE VALUE SHOWN IS THE ORIGINAL NUMBER OF STATISTICAL VOLUMES FOR
                  THE DATA SET.

 1  The MEGABYTES TRANSFERRED column shows the size of the most current version of the data set.

 2  The CURRENT STAT-VOLS column shows the current statistical volumes for the data set. See Statistical Volumes for more information about statistical volumes.
