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.
