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

       /FILE_PROTECTION=code

    Affects Files-11 On-Disk Structure Level 1 disks only.

    Defines for disk volumes the default protection to be applied to
    all files on the volume.

    Specify the code according to the standard syntax rules described
    in the OpenVMS Guide to System Security. Any attributes not
    specified are taken from the current default protection.

    Note that this attribute is not used when the volume is
    being used on an OpenVMS system, but is provided to control
    the process's use of the volume on RSX-11M systems. OpenVMS
    systems always use the default file protection. Use the
    SET PROTECTION/DEFAULT command to change the default file
    protection.
