UWKPG Prolog

 Name       : HCPUWKPG
 Description: INDICATE USER data block
 DSECT      : UWKPG
 Function   : Contain information gathered to process the
              INDICATE USER command.
 Located by : Registers in INDICATE USER modules
 Created by : HCPTHLU
 Deleted by : HCPTHLU
 Serialized : Task execution: each time the task is run a new set
              of pages is obtained to hold the UWKPG maps; the
              data is first collected, then used, and finally the
              pages are deleted
 Comments   :
              This control block is used to map entries in
              storage that is fetched and released by the
              page.
              This control block is used to map the data gathered
              for both the old response and the expanded response
              to the Indicate user command.  Some fields are not
              used when processing the old response format.
