GD -- Sets graphics display parameters
  GD INI
  GD width dlength gcolor glength
Parameters:
  INI     | initializes the graphics parameters to their logon values
  width   | graphics line width in pixels; range 1-64 (def=last value set;
            at logon it is set to 1)
  dlength | pixel length of dashes in lines; range 0-64 (def=last value
            set; at logon it is set to 10)
  gcolor  | graphics color level of gaps in dashed lines (def=last
            value set; at logon it is set to 255, transparent)
  glength | pixel length of gaps in dashed lines; range 0-64 (def=last
            value set; at logon it is set to 10)
Remark:
  Enter GD with no parameters to list the current graphics settings.
Example:
  GD 3 5 3 5
  Sets the line width to 3 pixels; sets the length of dashes and gaps in
  the dashed lines to 5 pixels; sets the color of the gaps to color
  level 3.
