     NAME       : HCPPEDBK
     DESCRIPTION: Product Enablement Data Block
     DSECT      : PEDBK
     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
     RELOCATION CONSIDERATIONS : None
     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.
