Dylan is a new programming language invented by Apple Computer and developed with Harlequin and other partners. The language is both object-oriented, like C++ and Java, and dynamic, like Smalltalk. Dylan is designed to deliver applications that run efficiently on a wide range of platforms. It also facilitates the rapid development and incremental refinement of prototype programs. Dylan is a good choice for any application, but you will find it particularly useful for complex object-oriented programs, and for programs that may need to be changed "on the fly." Public-domain implementations of Dylan are available for most popular computer systems. Harlequin has developed the first complete, commercial implementation of the language - including both compiler and development environment. Dylan Programming gets you started quickly, with a simple but complete program that lets you experiment with the language. It then leads you progressively through the development of a sample application, illustrating advanced topics such as macros, modules, libraries, inheritance, performance, and exceptions. This book is appropriate for any Dylan implementation. It assumes you can program in a conventional language, but requires no prior knowledge of object-oriented or dynamic techniques.
