/PFN [=(option[,option,...])]

    Displays PFN data in addition to the basic SHM_CPP. The default
    is to display all lists (free, bad, untested), plus the PFN
    database pages and the complete range of PFNs in the CPP.

    You can limit which lists are displayed by specifying one or
    more keywords from the following table. If you specify multiple
    keywords, enclose them in parentheses and separate keywords with
    a comma.

    ALL_FRAGMENTS   Displays the complete range of PFNs in the CPP.
    BAD             Displays only the bad page list.
    FREE            Displays only the free page list.
    PFNDB           Displays the PFNs containing the PFN database.
    UNTESTED        Displays only the untested page list.

    If you specify /PFN without /ALL, /IDENT, or /ADDRESS, the system
    displays the PFN lists from the last shared memory CPP accessed.
