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)

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 use of the Prolog programing language is promoted as the language to use by anyone teaching a course in relational databases. A short introduction to Prolog is followed by a series of examples of queries. Several references are noted for anyone wishing to gain a deeper understanding. (MP)

Describes a computer activity (for Apple II) showing junior high students with some programing experience how to make words/letters in original programed poetry move on the computer screen (and gives practice using simple arrays, FOR..NEXT loops, and DATA statements). Includes the complete activity which can be duplicated for classroom use. (JN)

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)

Two kinds of secret writing, codes and ciphers, are discussed. The weakness of a ciphering system mentioned in the March 1981 issue is pointed out, and an alternate method is presented. Programs written in BASIC are presented which can be used to encipher messages and help break ciphers. (MP)

Three-Key Logo is a useful method for introducing young children to Logo because it does not require numbers skills and eliminates typing slow-down. Briefly outlines the method and provides an exercise which may be duplicates for classroom use. (JN)

Making Cryptograms is designed to give middle grade students practice in using the FIND and REPLACE features on their word processors. An activity sheet (which may be duplicated for class use) is provided. Instructional strategies are also provided. (JN)

A program written in PASCAL designed to find the number of binary trees possible for a given number of nodes is presented. The problem was found to be highly motivating and exciting for the group of introductory computer science students with whom it was used. (MP)

This article considers the sum of a finite geometric series as applied to numeric data storage in the memory of an electronic digital computer. The presentation is viewed as relevant to programing in several languages and removes some of the mystique associated with syntax constraints that any language imposes. (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)

Problems are presented that can be solved with a microcomputer which explore the binary, decimal, and hexadecimal number systems and related problems. (Author/TG)

A course syllabus and descriptive outline are provided for an introductory, three-credit college course at Lon Morris College, Jacksonville, Texas, covering logical operations and the development of basic algorithmic processes using the BASIC computer programming language. Overall goals, specific objectives, and a brief description of lesson…
