     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.
