## How to specify a point

The coordinates of a point can be expressed using the following syntax:

1) x,y

2) @length<angle (from the previous point you move to a distance using an angle)

3) @ x,y (from the previous point you move to a distance in the X axis and to another distance in the Y axis)

4) @ (previous point)

5) length (from the previous point you move to a distance using the current mouse position)

6) Coordinate specified in a coordinate reference system different from the current one
