      In this example, successive DEFINE PARTITION commands create a
      partition hierarchy.

      1  The root partition is FINAL_RELEASE.

      2  Each successive partition in the hierarchy is the child of
         the previous partition.

      3  A partition hierarchy can include multiple children of a
         previous partition; LOOKASIDE_PARTITION makes the contents
         of FRONT_END visible to BACK_END.

      4  The CHANGE PARTITION command makes the contents of BACK_END
         visible to FRONT_END.

      5  The base partition, or lowest visible partition, is set for
         three different contexts.
