/CONTIGUOUS
       /NOCONTIGUOUS

    Specifies that the created file is either to be contiguous
    (/CONTIGUOUS) or contiguous-best-try (/NOCONTIGUOUS). The
    Primitive File System used during OpenVMS bootstrap limits the
    page, swap, and dump files to one file header. Because of this
    restriction, OpenVMS cannot be reliably bootstrapped from a bound
    volume set and is not supported on a bound volume set.
