The LGI$ICR_LOGOUT callout routine permits the site callout
    images to respond to the DCL command LOGOUT.

                                   NOTE

       This routine is not called if the calling process is deleted
       with STOP/PROCESS ($DELPRC). If the calling terminal is
       disconnected when logout occurs, this routine must not
       produce output.
