The Plotter v12 n5

This month we provide an article on basic BASIC programming that hopefully will interest some of our readers. The author’s name, Jim Wagner, will be recognized as the provider of a writeup on his book, The Amateur Packet Radio Handbook in a recent newsletter.

Those who have re-inked larger printer ribbons know that it is almost impossible to use re-inking equipment without getting ink on one or more fingers. Rod Gowen, RMG Enterprises, recommends using WD 40 lubricant as a hand cleaner.

The puzzle this month is best solved by using linear equations in which variables are multiplied by constants and added together. This is the method used in the program. As noted, the original program is from the book, BRAIN GAMES FOR KIDS AND ADULTS, written for Apple computers.

John McMichael has a program and hardware that interfaces a 2068 computer and a Commodore 1520 plotter.

Much of what I list below is intended to improve programming “reliability”. You cannot have a program which works well and is free of bugs if you cannot understand it later and if you cannot do it close to right the first time. Thus, many of these things are designed to put up roadblocks to…

QBASIC solution to the cockroach story.
