Forget about changing the value via DELTA...  Changing the value after
the system is running will not grant you what you want.  Let me refer you
to a paraghaph in the top of pg. 487 in the IDSM.

"During system initialization, enough virtual address space is reserved
in each PHD for the maximum-sized working set list, one with SYSGEN
parameter WSMAX entries."

Changine the WSMAX value with DELTA will change the storage cell value
but not other pools and values reserved as a consequence of its initial
value.
