HLQBK Prolog
NAME : HCPHLQBK
STATUS : VM/ESA Version 2, Release 3.0
DESCRIPTION: Harware Loader Queue Block
DSECT : HLQBK
FUNCTION : The Hardware Loader Queue Block maintains a list of
active Hardware Loader Requests. A list of active
hardware request must be maintain to allow VM/ESA
bounce processing to terminate all active load
operations prior to restarting the system.
CREATED BY : Dynamically created by HCPMFNGB when the
first hardware load is performed.
DELETED BY : Never deleted once created.
