RDB/VMS RMU/ALTER HELP — VMS RDB_4.0

 The RdbALTER HELP command provides  information  about  RdbALTER
 commands,  terminology,  and  concepts.  If you type HELP at the
 RdbALTER prompt without specifying a topic, RdbALTER displays  a
 list  of  topics  on  which help is available.  If you type HELP
 followed by a topic, you get a brief description of that topic.

 VERIFY

   Verifies the current page statically.  In a static verification,
   no    sets    are    walked.     This    is    similar   to   an
   RMU/VERIFY/OPTIONS=SEGMENT  command,  except   RdbALTER   VERIFY
   checks  only  the current page.  If the database uses space area
   management and the current page is a data storage page, the SPAM
   entry for the current page is checked for correct value.  If the
   current page is a SPAM page,  the  page  is  checked  for  valid
   format,  but  the  individual  SPAM  entries are not checked for
   correctness.  Error messages are issued if the page is corrupt.
