Error description

• After reloading a large HDAM database with HP Load, the
  following pointer errors are reported by HP Pointer Checker:
       MSGFABP0470E  MSGFABP0960E
  HP Load attempts to place a RAP for synonym in the overflow
  area, and does not establish synonym chain when the synonym
  is placed into the block - whose block number above 4GB boundry
  is the same as that generated by randomizer.

  ****************************************************************
  After reloading a large HDAM database with HP Load, the
  following pointer errors are reported by HP Pointer Checker:
    MSGFABP0470E  MSGFABP0960E
  When a synonym is placed into the block just 4GB away from the
  root segment in the twin chain, HP Load misidentifies as they
  are placed in the same block. As a result, HP Load attempts to
  place a RAP for the synonym instead of chaining, and pointer
  errors are occur. Other kinds of pointer errors are possible
  depending on RAP number and prefix length.
  

Problem conclusion

• The module HPSRPTRS has been modified to handle block number
  correctly when a synonym is placed into the block just 4GB away
  from the root segment in the twin chain.
