This command applies a compass adjustment to a perimeter defined
by a polyline. The command draws a new polyline of the adjusted
perimeter and creates a report. The closure error is the difference
between the end point of the polyline and the specified closing
point that the program prompts for. For a closed loop adjustment,
the closing point is the starting point of the polyline. Here is an
example report for a closed loop.
