The aim of this book is to introduce and illustrate practically the structured techniques which are available for use during the development of a computer system. It is suitable for anyone who may be new to systems analaysis, including programmers who are making the transition to analysis. It attempts to reveal the reasons and the reasoning behind the methodologies of structured techniques through the use of case studies. This produces a systems development approach which is valid as an independent methodology and which will also prepare the reader for any more detailed methodology which may be implemented in his or her own working environment.
This book introduces readers to the Pick implementation of the BASIC programming language and covers the programming structures and statements, and the data structures which are encountered and is aimed at all levels of expertise. It should be a useful guide to this increasingly widespread programming medium. The book considers the compiler and the run-time processor and explains the way in which they affect the programmer, and includes interaction between BASIC programmes and TCL, Procs and other parts of the operating system and with other software.
The Pick operating system is a popular computer environment for commercial data processing. One of its features is the Access enquiry language which allows the users to make enquiries about their data and to produce reports based upon their files. Whether it is knows as Access, English, Info/Access, Inform, Recal or any of the other alias. The material in this book is relevant to implementation on several cognate systems. This book is designed to be of use to Pick users - the beginner and the end user who are just setting out to use Access, the experienced user who wants to get more out of the language, and the technical user. Firstly the general nature of the language is discussed and then detailed features with practical examples of its usage are given.
