Use Output point as Next Input Point
 
A user may wish to calculate the positions of a set of points (B, C, etc) starting at point A. The user knows:

1. Point B is azimuth 10 degrees, 1000 meters from point A and
2. Point C is azimuth 40 degrees, 1200 meters from point B,
3. The azimuths and distances from point to point.

The user may set up a column of azimuths, a column of distances, and select "Use Output Point...".
 
The Calculator will start at the first point (A) and calculate B's position from the azimuth/distance data. From point 'B' the coordinate of 'C' will be calculated, etc.
