 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.
