Analysis of Variance    
11 - Two Way Analysis of Variance (No

This program calculates a number of values for identical stations available to service calls from an infinite number of customers.
31 - Single- and Multi-Server Queues (Finite
       Customers)
This program is similar to program 30, but handles the case in which demand arises from a finite rather than an infinite population of customers.

01 - Field Angle Traverse This program will accept angles right, angles left, deflections right and deflections left as well as horizontal or slope distances. The coordinates of the next point are calculated, and area in square feet and acres are available upon completion of the traverse.
02 - Bearing Traverse This program uses bearings and horizontal or slope distances to calculate coordinates.
03 - Closure for Field Angle & Bearing Traverse This program, used in conjunction with either the Field Angle Traverse program (01), or the Bearing Traverse program (02), computes area, closure bearing and distance, total distance traversed, and precision ratio.
04 - Inverse From Coordinates This program uses coordinates to calculate distance and bearing between points of a traverse. The area in square feet and acres, plus a summation of distance inversed are also computed.
05 - Sideshots This program may be used alone or in conjunction with one of the traverse programs (01 or 02). Used as a stand-alone program, the reference bearing from a backsight is entered along with the coordinates of the occupied point. If used with a traverse program, these steps are omitted and data stored by a traverse program is used.
06 - Coordinate Transformation This program translates, rotates, and rescales coordinates.
07 - Compass Rule Adjustment (Also known as the Bowditch adjustment.) This program adjusts a traverse by the compass rule. It is intended to follow the program Closure For Field Angle and Bearing Traverses (03).
