Several problems that can be encountered with displaying numerical data are discussed, with particular view to some of the limitations on the Apple II computer. A subroutine in BASIC is listed which solves all of the problems for users who can use a scientific notation format. (MP)

The nature of many computerized community bulletin boards is described. A system called Communitree is profiled as a version with many distinct advantages over generic bulletin board systems. It is felt that their strong points are carefully orchestrated details, and their weak points are intelligent compromises. (MP)

Some of the important concepts in recursive programing are detailed, along with how they can be used. Examples are provided to show how to program recursively in BASIC. (MP)

A few basic principles that highlight the design of screen displays are detailed. It is noted that none of the principles will help programing efforts, but efforts at improvement in the direction described is expected to result in a more professionally designed work that users appreciate. (MP)

A mathematical technique for solving for the interest rate of a given annuity is explained. The technique is applied to a BASIC program that finds interest rate given the future value, number of payments, and the value of the payment. (MP)

A program written for the 16K Level II TRS-80 computer that prints a star map, using various mathematical formulas to compute positions of the stars and the moon and displays them on terminals, is discussed. Some relevant astronomical background and terminology are covered in order to aid understanding. (MP)

Describes a program written in BASIC, called BIGNUM, that was designed to aid in handling big numbers. The program adds, subtracts, multiplies, divides, and raises to a power integers of up to 1024 decimal digits and is thought to be usable on many types of machines. (MP)

There are many uses for the shortest path algorithm presented which are limited only by our ability to recognize when a problem may be converted into the shortest path in a graph representation. (Author/TG)

Some aspects of animation that are on the Apple-microcomputer are presented. Shape tables are described and several programs that illustrate important concepts are included. The concept of animation is viewed as being very simple and the process is clearly detailed. (MP)

The skills of prose composition and "top-down" computer programing, such as in BASIC, are viewed as closely interrelated so that careful attention to one will almost always bring improved competence in the other. The structure of this report is compared to a typical quiz/tutorial program to illustrate the point. (MP)

This material provides details on many of the commands available in the Pilot programing language. It is noted that some of the forms described may not be found in individual Pilot systems, but most Pilot implementations will have commands to equivalent things. A list of suggestions for purchase is given. (MP)

A program designed to calculate pi using a Monte Carlo simulation based on "throwing darts" at a quarter circle of unit radius inscribed in a unit square is presented. (MP)

A program designed to plot three-dimensional graphs is described and presented. The program allows the user to select maximum and minimum ranges for X, Y, and Z, and can enlarge a graph on the screen or look at a portion away from the origin. It is in Applesoft BASIC. (MP)

The problems used in the Second Annual Computer Problem Solving Contest are presented. There are three groups of five problems, which corresponded to Elementary, Junior, and Senior contest sets. The contest questions are seen as interesting for individual study, and potentially useful to teachers of computer programing. (MP)

Several BASIC computer programs designed to illustrate concepts in probability are presented. The programs are geared for the Apple II computer, but most samples are adaptable to other systems. (MP)
