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

    When you select EDT as your text editor, the /RECOVER qualifier
    indicates that you want to recover a previous editing session
    that was prematurely terminated. The /RECOVER qualifier will work
    only if there is an existing .JOU file. This qualifier cannot be
    specified if you are using an editor other than EDT.
