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

       /LOGOUT (default)
       /NOLOGOUT

    Logs out your current process when you connect to another process
    using a virtual terminal.

    When you enter the CONNECT command from a process that is not
    connected to a virtual terminal, you must specify the /LOGOUT
    qualifier; otherwise, DCL displays an error message.

    The /LOGOUT qualifier is incompatible with the /CONTINUE
    qualifier.
