Checks a dictionary to determine if it is structurally correct.  This
 command finds errors in the dictionary and in the dictionary directory
 structure.  Except for the /ALL and /REBUILD_DIRECTORY qualifiers, the
 VERIFY command fixes errors only when the /FIX qualifier is specified
 with other qualifiers.

Additional information available:

anchor-nameQualifiersExample

 Specifies the anchor of the dictionary to be checked.

Additional information available:

/ALL/COMPRESS/DIRECTORY/EXTERNAL_REFERENCE
/FIX/LOCATION/LOG/ORPHANS/REBUILD_DIRECTORY

 /ALL

 The /ALL qualifier performs all of the verification options (including
 /FIX), except for /REBUILD_DIRECTORY.

 /COMPRESS

 The /COMPRESS qualifier compresses the CDD$DATABASE.SNP to its original
 size at the time the dictionary was created.  The /COMPRESS qualifier
 cannot be used with other qualifiers.  It must be used alone.

 /DIRECTORY
 /NODIRECTORY (default)

 The /DIRECTORY qualifier checks all directory names against the stored
 object.  When the /FIX qualifier is specified, directory names that do
 not refer to any stored object are removed.

 /EXTERNAL_REFERENCE
 /NOEXTERNAL_REFERENCE (default)

 The /EXTERNAL_REFERENCE qualifier checks all relationships in which the
 owner or the member is outside this dictionary.  When the /FIX
 qualifier is specified, the /EXTERNAL_REFERENCE qualifier fixes the
 errors it detects.

 /FIX
 /NOFIX (default)

 The /FIX qualifier corrects errors that are found.

 /LOCATION
 /NOLOCATION (default)

 The /LOCATION qualifier confirms that the dictionary is in the correct
 VMS directory and is correctly reference by other dictionaries on the
 system.  When the /FIX qualifier is specified, the /LOCATION qualifier
 fixes the errors it detects.

 /LOG
 /NOLOG (default)

 The /LOG qualifier reports informational messages as well as error
 messages to SYS$OUTPUT.  The /NOLOG qualifier reports only error
 messages.

 /ORPHANS
 /NOORPHANS (default)

 The /ORPHANS qualifier causes the VERIFY command to search for objects
 that have no directory name and are not an owner or member of any
 relationship.  When the /FIX qualifier is specified, it places these
 objects in a directory called CDD$ORPHANS.  The CDD$ORPHANS directory
 is created during the execution of the VERIFY command.  The objects in
 the CDD$ORPHANS directory have directory names created for them during
 the execution of the VERIFY command.

 /REBUILD_DIRECTORY
 /NOREBUILD_DIRECTORY (default)

 The /REBUILD_DIRECTORY qualifier deletes and recreates all directory
 entries for the specified anchor.  Use the /REBUILD_DIRECTORY qualifier
 to recover:

  o  A directory system for a dictionary VAX Rdb/VMS database
     (CDD$DATABASE.RDB and CDD$DATABASE.SNP files) that has been backed
     up with RDO (Relational Database Operator) or RMU (Relational
     Management Utility).

  o  A severely corrupted dictionary system that VERIFY/FIX/DIRECTORY
     could not fix.



                            WARNING

 DIGITAL recommends that you back up your dictionary before using the
 /REBUILD_DIRECTORY option. You should use the /REBUILD_DIRECTORY
 option only when corruption is so severe that all other options
 fail.

 The following command checks the DISK1:[SMITH.DICT] dictionary and
 corrects the errors detected:
