A number of papers are concerned with advances in simulation techniques particularly in relation to continuous systems simulation. The application papers, which provide the major part of the volume reflect the wide applicability of continuous and discrete event simulation to science, engineering and social-economic systems.

BOOK REVIEWS The Uses of Microprocessors G. L. Simons N.C.C. P u b l i c a t i o n s If you have ever wanted to know what a microprocessor could be used for this book may well provide many answers, It does not claim to cover all the uses of microprocessors, but certainly seems to cover many of them. The workings of a microprocessor are not described in detail as the book is aimed towards the large majority of people who need no technical knowledge of electronics. The areas of application are divided into 9 broad areas; business/offices-terminals and peripherals- industry; multiprocessors and development systems; communications; eductation; medicine; transport and domestic/entertainment. These are each then further subdivided, typically into ten sections. The bibliography is very extensive, so finding any further information should be quite easy. The book is published by NCC Publications, part of the National Computing Centre. This organization is a non-profit distributing organisation, backed by industry and government, and can provide help in many aspects of computing. NCC also publishes a regular journal entitled 'NCC Interface'. They can be contacted on 061 228 6333. Other books by NCC include "Introducing Microprocessors', 'The Impact of Microprocessors on British Business', and 'High Level Languages for Microprocessor Projects'.

Yhe sleeve notes for this book justifiably recommends the book for all users, from managers through systems designer to hobbyist and student. The only assumption made is a basic knowledge of computer operation. Before going into details, the book briefly explains the concept of using binary numbers to represent characters (e.g. the ASCI 1 code), which-are often used to convey the information to peripheral devices. The book considers not only the obvious peripherals - - printers, keyboards, VDU's, punches and readers, but also several which are not so obvious - - light pens, graphic plotters, speech input and output, magnetic tapes and disks, modems, and position digitisers. Memory types, not normally conserved as a peripheral, are also included. The operational principles of each device are described, and together with the many (over 200) photographs, make the explanations quite easy to follow. Specific technical details are sensibly left out. This is not. however, a book to help choose a specific model or manufacturer for a device, but to aid the understanding of what typical devices are capable of. For a non-technical person who is buying a computer for the first time, or who wants to know a little more about what he already has, this book would be of assistance.
