Displays an inverse between two points, containing the Horizontal and Slope distances, the bearing, the slope and grade, and the Delta X, Delta Y, and Delta Z values between the points. It can also maintain a running total of successive distances, adding the value of each measurement to the running total. Points may be selected on-screen, or by typing Cogo Point numbers at the prompt.
