Ralph E. Griswold (1) (1934–2006)

SNOBOL (and its rare cousin, SPITBOL) are that rara avis, languages meant for pure string manipulation. As SPL was (and is) used for fancy mathematical efforts with matrices, SNOBOL makes complicated handling of strings simple. With the advent of cleaner, easier scripting languages, like PERL and PYTHON, I believe that SNOBOL has fallen into sad disuse. At one time, I could write a compiler in 20 lines of SNOBOL. Now, I doubt I could put 20 lines together.

Sad to say, both Ralph and Madge are gone.… (mais)

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.

Icon is entirely free and can be downloaded from the Icon web site at:

Windows users may find it preferable to download Unicon, the extended version of Icon. The Unicon home page
is at:

This superb programming language deserves to be better known. Download it today!… (mais)

This book describes completely, the extensive graphics programming features of the
Icon Programming Language. A DVD is included containing examples. The book is
more or less essential for anyone wishing to use the graphics facilities of Icon.

I have successfully used Icon on Unix/Linux and Windows machines, and it is
available for Macintosh.
