MLTBK Prolog

 NAME       : HCPMLTBK
 DESCRIPTION: Multi-Level Table definition
 DSECT      : MLTBK
 FUNCTION   :
              The MLTBK structure defines a multi-level indexed
              table.  The MLTBK provides an anchor for sub-tables
              which are allocated only when required.  The width
              of the KEY determines the depth of the table.  Each
              byte of the KEY represents an index into the sub-table
              at that level of the structure.
 LOCATED BY -
   SLMMACTB - Instance of an MLTBK for System MACADDR
   LANIPTBL - Instance of an MLTBK for LAN IP Table
 CREATED BY :
              HCPMLTCR - Created/Initialized.
 DELETED BY :
              HCPMLTRL - Released.
 NOTES      :
              None
