1  ROLLBACK
   Ignores all page changes since the last COMMIT or last ROLLBACK
   command. Altered pages are stored in virtual memory until you
   issue a COMMIT or a ROLLBACK command. The ROLLBACK command tells
   RdbALTER to ignore all changes since the last COMMIT or the last
   ROLLBACK command was issued.

   Do not follow a ROLLBACK command with a DEPOSIT command without
   first specifying your location again with a DISPLAY or a PAGE
   command.

   RdbALTER does not allow you to issue an EXIT command until all
   altered pages are either committed or rolled back.
