 NAME       : HCPBMPBK
 DESCRIPTION: Bit map control block
 DSECT      : BMPBK
 FUNCTION   : HCPBMPBK is used to describe the local and
              global bitmaps which are used by VMDUMP.  It
              contains bitmap information and a mapping of
              the meta-map which points to each page of the
              local or global bitmaps.
