DLA segments provide a mechanism for grouping related data. For example,
   in the SPICE DSK format, which is a specialization of the DLA format,
   data are grouped into segments; each DSK segment is a DLA segment as
   well. DSK segments contain data representing shapes of extended objects.
   Such representations may use both integer and double precision data. For
   example, in DSK data type 2, segments contain double precision numbers
   that represent the vertex coordinates of triangular plates, and i
