The chainage of the start point of a reference line/arc can be defined.
It is possible to define an arc that has an opening angle of more than 180
It is possible to use a valid coordinate system but have the line or part of the line lying outside
of the projection or CSCS model being used.
In these cases the output fields of all prompts relating to the difference in coordinates
between the point being staked and the current position are shown as -----.
<Azimuth:> is used throughout this chapter. This can also mean <Bearing:>.
When describing screens with a title that changes depending on whether a line or an arc was
chosen, the terms "line" and "arc" are replaced by XX.
