This command is used to
restore a lost corner from new measurements between four known
corners with two measurements each on intersecting meridianal and
latitudinal lines. The program prompts for the four known corner
points to establish the retracement. Plus the program prompts for
the four sets of record bearings and distances from the known
points to the lost corner. The report then shows the calculated
point along with the input data.
