The VAX Common Data Dictionary's Verify/Fix Utility  (CDDV)  scans  a
 physical   dictionary   file   for  inconsistencies  and  reorganizes
 dictionary files to enhance efficiency.  The operator can examine  or
 alter  dictionary  files  with  any  of  three  commands.  The VERIFY
 command merely generates an  error  report,  while  the  FIX  command
 generates  an  error report and repairs the dictionary.  The COMPRESS
 command reorganizes a dictionary file.
