        LAS\SET SYSTEM Type [Equinox]

    Specify the coordinate system to be used by the  current  R  observation
    and  next ones loaded in memory. Type may be E[quatorial] followed by an
    epoch, G[alactic], or A[utomatic]. Default is Auto, i.e. uses  the  type
    found  in the data file. If the equinox of Equatorial coordinates is not
    specified, the previous value is used. The initial default  is  2000.00.
    Coordinates and offsets are automatically converted to the specified co-
    ordinate system and precessed to the specified epoch if needed.
