To run the inverse routine, enter the first point number at the bottom (you may also select from a point list or select from
the map screen). Press Enter, and then enter the second point and press Enter again.
If a control file is specified in Job Settings, then when you run inverse, you can choose the List icon at the bottom
center of the screen and then select points from the control file. In this way, you can inverse between points in your
current file and your control file as needed.
If under Units in Job Settings, Angle Unit is set to Grads/Gons, then the Inverse command will default to the 400 circle
and will display North azimuths.

used.
Areas
This command calculates the area of a closed figure that is defined internally by user-entered point numbers contained
within the current job, or by a polyline picked from the screen. The polyline method allows selection of figures with
arcs.
