Ebook: The Icon programming language

The Icon Programming Language is divided into four parts:

Part I covers the basic features of Icon, including its basic string-processing facilities; it
describes the subset of Icon that is similar in nature to several other programming
languages.

Part II introduces more advanced features, including generators, goal-directed
evaluation, string scanning, and co-expressions.

Part III is devoted to programming techniques—how to program with generators, string
processing techniques, list processing, and so forth.

Part IV presents several substantial Icon programs to illustrate how the features of Icon
can be used in combination and how specific problems are handled.

Appendix A summarizes the syntax of Icon. Machine dependencies and implementation
limits are described in Appendix B. Appendix C describes how to run Icon programs and
Appendix D summarizes error messages. Appendix E is a quick reference guide to the
functions, operations, and control structures of Icon. There are solutions to selected
exercises in Appendix F.
