      IHNAME - The currently defined names for variables, parameters, strings, functions, and matrices (characters 1-4).
      IHNAM2 - The currently defined names for variables, parameters, strings, functions, and matrices (characters 1-8).
      IUSE <elem> - The type for the <elem> entry in the Dataplot name table. V means variable, P means parameter, F means function or string, and M means matrix.
      IVALUE <elem> - The column in the internal data storage area where the <elem> entry in the Dataplot name table is stored.
      VALUE <elem> - The parameter value for the <elem> entry in the Dataplot name table. This value is only relevant if the type is a parameter.
      IN <elem> - The number of observations for the <elem> entry in the Dataplot name table. This value is only relevant for variables.
      IVSTAR <elem> - The starting position in the internal data storage area for the <elem> entry in the Dataplot name table.
      IVSTOP <elem> - The stopping position in the internal data storage area for the <elem> entry in the Dataplot name table.
