Just waft your pointer over the compass and numbers will magically appear. This is the "loc" the numbers refer to. The first and third are the important ones. The middle one is your coordinate in a vertical direction which is seldom helpful unless you are in a multi-storey building.
If you are terminally sad and retrograde like me you can always create a macro button to do a /loc command which then shows in your chat box.
