BOX [x1], [y1] TO x2, y2[, c ]
   BOX TO x2, y2[, c ]

This instruction draws a rectangle on the screen, starting from the coordinates (x1, y1) to arrive at the coordinates (x2, y2), using the color c. The start coordinates can be omitted: in this case, ugBASIC will draw starting from the last drawn position. If the color is omitted, the last color selected with the INK or PEN command will be used. Finally, the default line style is full but a 16 bit bitmask can be set with the SET LINE command.

  BOX 10,10 TO 100,100,WHITE
  BOX TO 100,100
  BOX ,10 TO ,100
