This is a book about the implementation of the Icon Programming Language. It is a 'computer science' book but
unlike many 'computer science' books, it is accessible to the ordinary user (a lapsed phycisist-cum-programmer
in this case). It describes completely, the implementation of the language including it's many innovative (at the
time) features, many of which have still not been implemented as successfully in other, later languages.

Icon is not, in this case, one of those funny little pictures you click on on your computer screen. It is a fully featured
computer programming language developed by the late Professor Ralph Griswold and his team at the University
of Arizona. Co-authors of this book is Professor Griswold's wife, Madge T. Griswold.

Ralph Griswold was also largely responsible for the programming language Snobol, and several other development
languages.

Remember that the use of the name Icon for the programming language pre-dates the use of 'icon' for those funny
little pictures you see on your computer screen.
