The QWP4PSPN field was added to trace the internal setting of the new subsystem  parameter PAGESET_PAGENUM, as shown in Example 12-26. IFCID 124 was modified to include the page number within the page set, QW01244N, as  shown in Example 12-27. As with IFCID 006 and 007, IFCID 127 was modified to include a flag that indicates whether  the page number is relative or absolute and to include the partition number, when applicable.  The new flag and partition number field in IFCID 127 is shown in Example 12-28.
