                           --------------------------

    This  program converts a file of ReGIS graphics commands (as used by the
    VT125  and  VT240  terminals)  into  Hewlett-Packard  Graphics  Language
    (HP-GL)  (as  used on the 7470A plotter), and sends them to the  plotter
    via an HPIB interface.  All ReGIS commands are parsed, but only a subset
    (sufficient  for line graphs with labelling, and including  macrographs)
    is sent to the plotter.  The  resulting  graph  is designed to fit on A4
    paper,  and  is approximately the same size as that produced  using  the
    'expanded print' option  of  the  VT240.   The  program  is  designed to
    facilitate  the  addition  of  extra ReGIS commands or  the  use  of  an
    alternative interface (e.g. RS232).
