             the newest module might be included in a load module.

       Specifies the write-ahead data sets (WADSs) (where n is 0
       - 9). You can specify all WADSs used during IMS online
       execution, but you must include the WADS that was in use
       when IMS failed. To avoid executing IMS DEDB Fast Recovery
       against the active IMS system, you must specify DISP=OLD
       in the DD statement.

       The WADS defined as a large format data set can be
       specified.
