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

       /ACCOUNTING
       /NOACCOUNTING (default)

    Enables image-level accounting for the specified image even
    if image accounting is disabled (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.
