The code starts with the {{U}} which lifts the pen ({{U}}p) so the following commands will not draw to the screen. This is followed by a {{2}}, which means the next instruction should be run twice. In this case, the next instructions is {{L}}eft. Since each step of a turn is 45 degrees, this causes the turtle to rotate 90 degrees to the left so it points to the left side of the screen. Next, the turtle moves {{F}}orward 12 steps, is pointed {{N}}orth (up, 2R would do the same thing), and then put back {{D}}own so the following commands will cause drawing on the screen.
