is particularly suited for readers with no prior programming knowledge. Starting from the first principles of programming, it teaches you how to use and create algorithms (reusable rules for problem-solving) and the basic building blocks of software. It goes on to explain how to develop complete applications and has a whole chapter on web applications as well as case studies. Now translated into English, this edition was completely revised to be consistent with the latest version of Cincom® VisualWorks®, a professional Smalltalk environment. All examples were created using VisualWorks, which is available without cost for educational purposes, and can be downloaded and installed on any up-to-date computer.
