VMS Help ANALYZE, /OBJECT, Qualifiers, /INTERACTIVE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /INTERACTIVE
       /NOINTERACTIVE (default)

    Controls whether the analysis occurs interactively. In
    interactive mode, as each record is analyzed, the results
    are displayed on the screen, and you are asked whether you
    want to continue.
