Use Enables definition of graphics window, i.e. area of screen inside which graphics can be drawn with the @DRAW@ and @PLOT@ statements. Graphics (including sprites) are cropped to appear only within the graphics window. h4. Syntax VDU 24,__lx__;__by__;__rx__;__ty__; h4. Parameters |<^{width:8em}. _lx_|<^. Left X (inclusive)| |<^. _by_|<^. Bottom Y (inclusive)| |<^. _rx_|<^. Right X (inclusive)| |<^. _ty_|<^. Top Y (inclusive)| h4. Notes Four coordinates given as two bytes each, relative to the graphics origin. Use of semi-colon punctuation sends number as two-byte pair: lo followed by hi. If the graphics window has a negative width or height, it will _not_ crop the graphics, instead the whole screen will be accessible to plotting operations. Care should be taken if this is not the desired result. h4. See also * "Draw Module Technical Details: Stroking and Filling":Draw+Module+Technical+Details#stroking
