He shows you how to lay out a program clearly, how to write it in modules, each one of which can be tested before being incorporated into the whole. He looks at the most common things which go wrong in the areas of sound, graphics and procedures. Above all, he stresses the importance of making regular saves and backups of your work. </p> <p> Whether you're a beginner taking your first steps in BASIC or already tackling machine-code programs, you are bound to find this book useful. </p> <p> Further machine-specific versions of this book are available for the Spectrum and the Commodore 64. </p>
