DEVICE

        [GTVL\]DEVICE Dev_Type [Mode] [/OUTPUT Dev_Name]

    Directs graphic output to the graphics device of the specified type  and
    sets  default  values  for  the plot region location and device physical
    limits. The basic unit is 1 cm for hardcopies. All plots to  interactive
    devices  are made with some pre-computed factor to match the screen size
    to the Plot Page size, defined by command SET PLOT_PAGE (default size is
    an A4 format page, 30 by 21) .

    Use DEVICE ? to get the list of recognized graphics  devices  or  DEVICE
    type ? to get the list of modes on a given device.

    /OUTPUT Dev_Name  Allows you to direct the graphic output  to  something
    else  than your own terminal (TT:). Note that some specific devices will
    not support this  option:  this  is  currently  the  case  for  X-Window
    devices.

    Bitmap color is only available with DEVICE IMAGE on X-Window terminals.
