INTRODUCTION
The programs contained in this booklet are a brief
representation of the many problems which may
be solved on the HP-35 Pocket Calculator. The
intention is to provide routines for the more
widely encountered areas of surveying--traverses,
intersects, curves, areas, and triangles.
We hope that you find this booklet useful in your
day-to-day calculations.
