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

       /EXIT
       /NOEXIT

    The /EXIT qualifier terminates the Analyzer session before
    invoking the editor. The editor is then run in the same process
    and you are returned to DCL level when exiting the editor.

    The /NOEXIT qualifier returns you to the Analyzer session when
    you exit the editor. /NOEXIT is the default.
