 NAME       : HCPBMGBK
 DESCRIPTION: Bit map control block (z/architecture mode)
 DSECT      : BMGBK
 FUNCTION   : HCPBMGBK 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 pointer pages, which point
              to the local or global bitmaps.
