/sys$common/syshlp/helplib.hlb LSEDIT, Command Qualifiers, /RECOVER  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /RECOVER
  /NORECOVER (D)

  Directs LSE to use the latest version of  the  file  specified  as  the
  value  to  the /JOURNAL qualifier to recover changes that may have been
  lost due to a previous abnormal LSE termination.  Care must be taken to
  restore  the  editing  environment to the state that it was in when the
  journaled editing session began.

  /RECOVER should be  used  only  when  attempting  to  recover  using  a
  keystroke  journal  file.  If you wish to recover using a buffer change
  journal file, use the RECOVER BUFFER command in LSE  after  the  editor
  has been started.
