  • Chapter 1: A Brief Introduction To Logo

    This briefly introduces the reader to the language Logo. It covers the setting up of CP/M to load Logo. It outlines the basic graphics commands like FORWARD, BACK, RIGHT, LEFT, CLEARSCREEN etc. It discusses the use of REPEAT and shows how to create procedures. Editing procedures is also covered.

  • Chapter 2: Displaying Data; Using Random Numbers

    Here the reader will see how to format discs and LOAD & SAVE procedures and disc files. The use of variables is introduced and a series of absolute commands such as SETPOS are described. The RANDOM command is also described and its use in Monte-Carlo analysis outlined.

  • Chapter 3: Decision Analysis

    In this chapter, greater flexibility and innovation are encouraged and facilitated by the introduction of further commands. The chapter develops a method for managerial decision analysis on a user/computer interactive basis.

  • Chapter 4: Sales Forecasting

    This chapter adopts a case study approach to forecasting and develops procedures to collect data. Using this information, it makes predictions using ‘last period', ‘simple average', ‘moving average' and ‘exponential smoothing' techniques. Seasonal variations within the data are also accoutned for.

  • Chapter 5: Investment Analysis

    Here procedures are developed for investment analysis purposes; it uses ‘payback period' and ‘discounted cash-flow' methods to give a variety of information concerning investment alternatives.

  • Chapter 6: Production Scheduling

Introduction

Many different languages are available for use with computers, some more sophisticated than others, some for specialised use and others for general-purpose use. As most home microcomputers are sold with the BASIC language, many beginners use this to communicate with a computer for the first time. Increasingly, however, Logo has become available as an alternative to BASIC. Logo is unique in that it is the first powerful language designed specifically for the beginner. It has been designed as an introductory language for everyone regardless of age or academic ability to use and enjoy.

Applied Logo is the second book in a series; the first, ‘Using DR Logo on the Amstrad', adopts a more traditional approach using graphics and text computer applications that have a very wide appeal.

‘Practical Logo' however makes use of more useful possible applications including decision analysis, stock control, investment analysis, simulation techniques, forecasting, production scheduling etc. It attempts to point the reader/user towards the more serious uses of Logo that make it a viable alternative to BASIC.

Throughout this book a large proportion of the available syntax is considered. The user, having read this book, will be in a position to make good use of the full language as described in the sourcebook provided with the Logo.

L'Amstrad CPC est une machine 8 bits à base d'un Z80 à 4MHz. Le premier de la gamme fut le CPC 464 en 1984, équipé d'un lecteur de cassettes intégré il se plaçait en concurrent  du Commodore C64 beaucoup plus compliqué à utiliser et plus cher. Ce fut un réel succès et sorti cette même années le CPC 664 équipé d'un lecteur de disquettes trois pouces intégré. Sa vie fut de courte durée puisqu'en 1985 il fut remplacé par le CPC 6128 qui était plus compact, plus soigné et surtout qui avait 128Ko de RAM au lieu de 64Ko.
