In 1985 Niklaus Wirth and Jurg Gutknecht embarked on a project to build a new workstation from scratch. The quote from Einstein: 'Make it as simple as possible, but not simpler' served as a signpost for their approach resulting in a system of exemplary lucidity, efficiency and compactness. Wirth was fascinated by the accuracy and reliability of the Voyager space probe then passing Oberon, one of the moons of Uranus. The project was christened Oberon in its honor. This is the definitive guide to the Oberon language developed as a successor to Pascal and Modula 2. Programming in Oberon provides: *A programming tutorial that demonstrates modern programming concepts; *A complete language reference that explains the syntax and use of Oberon. This unique tutorial will be suitable for students learning Oberon as well as providing a valuable reference for professional programmers. Key features of the book *An early introduction to procedures and modules; *A unifying series of examples of increasing complexity which build up throughout the book towards a complete realistic simulation package; *An explanation of the object-oriented style of programming and its advantages.
