HELPLIB.HLB  —  RMS  NAML
    On Alpha systems, the long name block (NAML) can optionally take
    the place of a NAM block. The NAML allows OpenVMS Alpha users
    to locate and use file specifications that are longer than 255
    bytes.

    The following table describes the NAML field offset, size,
    corresponding NAM or FAB field, and description.
