PEDBK Prolog
Name : HCPPEDBK
Description: Product Enablement Data Block
DSECT : PEDBK
STATUS : VM/ESA Version 2, Release 3.0
Function : Contains information relating to Products
that are explicitly marked Enabled or Disabled
on the system.
Located by : SYSPEDBK pointer of system. These control
blocks are kept in SORTED order using PEDPRDID
as the key.
Created by : HCPPEC, HCPPES
Deleted by : HCPPEA
Serialized : SYSPEDLK Lock in System Common area
USAGE NOTES : The next field MUST be retained as the FIRST
data field within the control block. The
chaining routine in HCPPEA requires this to
be at offset zero.
