/sys$common/syshlp/helplib.hlb Sys Parameters, CLASS_PROT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    CLASS_PROT performs the nondiscretionary classification
    checks. CLASS_PROT is also checked by XQP to determine if a
    classification block should be added to the header of any created
    files.

    CLASS_PROT is a DYNAMIC parameter.
