| Syntax |
| WINDOW [[SCREEN] (x1,y1)-(x2,y2)] |
| |
| The WINDOW statement allows the user to create a customized coordinate |
| system to draw lines, graphs, or objects without being constrained by the |
| screen's physical coordinates (the dimensions of the screen). This is |
| done by redefining the screen-border coordinates with the "view coordinates" |
| (x1, y1) and (x2, y2). These view coordinates are single-precision numbers. |
| |
| WINDOW defines the section of the view coordinate system that is mapped to |
| the physical coordinates of the screen. All subsequent graphics statements |
| use these new view coordinates and are displayed within the current |
| viewport. (The size of the viewport can be changed with the VIEW statement.) |
| |
| The RUN statement, or WINDOW with no arguments, disables the window |
| transformation. |
| |
| The WINDOW SCREEN variant inverts the normal Cartesian direction of the |
| y coordinate, so y values go from negative to positive from top to bottom. |
