I want to calculate a route, like Google Maps. Where and how do I enter the origin and destination coordinates, preferably by giving two addresses, but also by clicking points on the map? Having got the generated route, I want to alter the route by adding mandatory waypoints.

I have looked through the posts and the online Help but cannot find any description of the procedure. Thanks in advance for anyone who can help.
