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)

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)

This text is designed to give individually paced instruction in Fortran Programing. The text contains fifteen units. Unit titles include: Flowcharts, Input and Output, Loops, and Debugging. Also included is an extensive set of appendices. These were designed to contain a great deal of practical information necessary to the course. These appendices…

It is noted that there are some integrals which cannot be evaluated by determining an antiderivative, and these integrals must be subjected to other techniques. Numerical integration is one such method; it provides a sum that is an approximate value for some integral types. This module's purpose is to introduce methods of numerical integration and…

Discussion focuses on the nature of computer-generated speech and voice synthesis today. State-of-the-art devices for home computers are called text-to-speech (TTS) systems. Details about the operation and use of TTS synthesizers are provided, and the time saving in programing over previous methods is emphasized. (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)

These student materials--study guides, handouts (some are manuals), a workbook, and programmed texts--for a secondary-postsecondary-level course for communications computer programmer are one of a number of military-developed curriculum packages selected for adaptation to vocational instruction and curriculum development in a civilian setting. A…

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)

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)

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)
