Instead, choose the language called "Essentials of Programming Languages". (The "Choose Language" menu item is in the "Language" menu.) Depending on your version of the book code, you might have to move a `define-datatype' declaration before its use in `cases'. Matthew </pre> </blockquote> </body> </html>
