BAR

The BAR instruction will draw a filled rectangle on the screen, specifying the coordinates of its opposite corners. The x1 and y1 are the left top coordinates, while the x2 and y2 are the right bottom coordinates.

The fill color could be the one predefined, or specified by additional parameter. The start or the final coordinates can be omitted: in this case, ugBASIC will draw, respectively, starting from the last drawn position and arriving at the last drawn position.

Drawing (and filling) rectangles is a common operation in graphics. A dedicated command would make the code more concise and readable. Filled rectangles can be used to create buttons, text boxes, and other interface elements. The BAR command could be used as a basis for creating more complex shapes.
