Programming Notes and Hints for the HP 35s Scientific Calculator

This little book is an attempt to supplement the HP 35s User’s Guide for those things this author had trouble understanding or discovered only after trial and error. It concentrates on topics such as programming, using memory, using Reverse Polish Notation (RPN), using stack registers, program construction, and working with equations (the equation solver).The book is a general programming guide, rather than a how-to guide for specific specialty areas. It does not discuss integration, mathematical transformations, logical operations, or conversion factors. It assumes RPN (Reverse Polish Notation) throughout.Although the HP 35s lacks a computer interface and a graphics display, it is reasonably priced (about $50 in June 2017), and has other desirable features. Its greatest strength is perhaps its capacity to store custom programs and equations specific to an individual’s needs.This book does not cover every aspect of the HP 35s. Therefore it is important to have the HP 35s User’s Guide which is available free online.
