1 Screen_Devices

  The  screen  devices  that can  be  referred  to by  name  depend on the
  graphics   package  used. Below  I list  most  of the  devices  that are
  available.  The  letters  following  the  name  indicate which  graphics
  package they are available in.  (G = GKSGRAL, V = DECGKS,
  DG = DEC GKS-3D, DI = DI3000, X = X Windows, P = PLTSUB). You can use
  any other device by giving its number (see the relevant  manual). You
  can find the complete list of devices available by asking for help when
  you start up Mn_Fit or giving the command `CAPTURE ?'.

  When you start up Mn_Fit you will  be prompted for which device you want
  to use.  Give a ? when  asked for the screen  device at the beginning of
  Mn_Fit  to find  out which  ones  are  available. If  your  Tektronix is
  another  device  you  must give  the  logical  name for  the  device. In
  addition you must be able to allocate the device for it to work.

  In X Windows you can specify the display in the following ways when
  you are prompted inside Mn_Fit. However this does not work for Decnet
  communication on VMS:
    <CR>          uses the DISPLAY name and line 10 of higz_windows.dat
    n.hostname    DISPLAY is set to hostname and added to higz_windows.dat
    n             DISPLAY is taken from line n of higz_windows.dat if available
    n.            DISPLAY uses environment variable DISPLAY and line n of
                  higz_windows.dat

  For the X windows version you can define the DISPLAY variable before you
  start Mn_Fit or in the command line
  (using `-n hostname' (Unix) or
  `-n hostname -t transport -s server' (VMS)).
  The transport is usually either decnet or tcpip (for Multinet
  tcpip).  The host name is either the decnet name or the tcp/ip
  name. If you specify the display in one of these ways just hit `<CR>'
  when prompted for the screen device. Line 10 of `higz_windows.dat'
  will be used to set the display size. If you start the X windows
  version and the environment variable `DISPLAY' is not defined and if
  you do not give the `hostname' then ``hostname`' (Unix) will be
  used.  Under VMS if the logical `decw$display' is not defined, then
  the display will be set to `sys$node'.

  `hostname' is of the  form `host:m' where  `host' is the host name (e.g.
  `hpl3cmu3.cern.ch') and  `m' is  the  display  number  (usually  0). The
  `higz_windows.dat' file is searched for in your  current directory and
  then in your home directory. If it does not exist it is created in your
  home directory. It  contains 10  lines with the  format `4(1X,I4),1X,A'.
  The four numbers are the x and y sizes of the display and the offset from
  the top left corner (in  pixels). The character  string is the `DISPLAY'
  name. `higz_windows.dat' is initially created with  display sizes of 600
  pixels and 0 offsets. If you are logged directly onto a computer or
  use `ssh' to connect to another computer `DISPLAY' should always be
  set correctly.

  Device `None' is useful if you  want Mn_Fit to go through the motions of
  making a picture  without actually making one,  as in `FUNCTION HIST' if
  you just want the histogram without looking at it:

  None        All           Capture a null device.

                            and the logical name if it is another device.

  For DI3000  you must  define which  devices  you want to  have available
  before   you  start   Mn_Fit.  You  have to   check  your  local  DI3000
  documentation  to  find out  what  devices you can  define.  Help inside
  Mn_Fit will then tell you what you have defined.
