VIEW Statement

 Action

 Defines screen limits for graphics output.

 Syntax


  VIEW  SCREEN ( x1!,  y1!)-( x2!,  y2!) ,  color& ,  border&


 Remarks

 The list below describes the parts of the  VIEW statement.

-----------------------------------------------------------------------------
 Part                                    Description
 ----------------------------------------------------------------------------
  SCREEN                                 Specifies that coordinates of
                                         subsequent graphics statements are
                                         absolute to the screen, not
                                         relative to the viewport. Only
                                         graphics within the viewport are
                                         plotted. When  SCREEN is omitted,
                                         all points are plotted relative to
                                         the viewport ( x1! and  y1! are
                                         added to the coordinates before
 Part                                    Description
 ----------------------------------------------------------------------------
                                         added to the coordinates before
                                         plotting the point).

 ( x1!,  y1!)-( x2!,  y2!)               Indicates a rectangular area on
                                         the screen. The arguments  x1!,
                                         y1!,  x2!, and  y2! are numeric
                                         expressions that are the
                                         coordinates of diagonally opposite
                                         corners of the viewport. The
                                         argument  ( x1!,  y1!)-( x2!,  y2!)
                                         must be within the physical bounds
                                         of the screen in the current
                                         screen mode.

  color&                                 A numeric expression that
                                         specifies the color with which to
                                         fill the viewport. If you omit
                                         color&, the viewport area is not
                                         filled (it has the same color as
 Part                                    Description
 ----------------------------------------------------------------------------
                                         filled (it has the same color as
                                         the screen background color).

  border&                                Any numeric expression for
                                         border& causes a line to be drawn
                                         around the viewport. The value of
                                         border determines the color of the
                                         line. If you omit  border&, no
                                         line is drawn around the viewport.




 The  VIEW statement defines a viewport or "clipping region," which is a
 rectangular section of the screen to which graphics output is limited. If
 VIEW is used with no arguments, the entire screen is defined as the
 viewport.  RUN and  SCREEN also define the entire screen as the viewport.
