The pages on this site contain documentation for very old MS-DOS software,

If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
VIEW Statement (Graphics) Details
◄Syntax► ◄Details► ◄Example► ◄Contents► ◄Index► ◄Back►
──────────────────────────────────────────────────────────────────────────────
The VIEW statement defines a graphics viewport, or "clipping region", which
is a rectangular area of the screen to which graphics output is limited.
VIEW [[SCREEN] (x1!,y1!)-(x2!,y2!) [,[color&] [,border&]]]
■ When SCREEN is used:
- The x and y coordinates of subsequent graphics statements
are absolute to the screen, not relative to the border of
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 coordinates before plotting the point).
■ (x1!,y1!)-(x2!,y2!) must be within the physical bounds of the
screen in the current screen mode.
■ If you omit color&, the viewport area is not filled (it has
the same color as the screen background color).
■ If you omit border&, no line is drawn around the viewport.
Usage Notes
■ 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.
