VMS Help INSTALL, REPLACE, Qualifiers, /ACCOUNTING  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /ACCOUNTING
       /NOACCOUNTING (default)

    Enables image-level accounting for selected images even if image
    accounting is disabled on the local node (by using the DCL
    command SET ACCOUNTING/DISABLE=IMAGE). When image accounting
    is enabled on the local node, it logs all images, and the
    /NOACCOUNTING qualifier has no effect.
