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

    Specifies whether the Convert utility uses a fast-loading
    algorithm for indexed files.

    Format

      /FAST_LOAD  (DEFAULT)

      /NOFAST_LOAD

    By default, the Convert utility uses the fast-loading algorithm,
    but if CONVERT/FAST_LOAD is executed across a network, the
    Convert utility automatically changes from /FAST_LOAD to
    /NOFAST_LOAD.
