SHARP APL Source Code
SHARP APL source code (circa 1989). This is posted for educational and historical purposes and may not represent a fully working system. Tools associated with a full system (e.g., assembler, link-editor, IBM 370-code simulator, graphics driver, workspaces) may also not be included. Likely this was a version used to generate the PC version of SHARP APL. NOTE: The original files are ANSI encoded but look to have originally contained APL characters (which are no longer displayed as such). As a result, the comments and some other lines are sometimes hard to read. A secondary zip file has been added which attempts to convert the files to UTF8 and to change some characters back to APL. A zip file of SHARP APL/PC workspace listings has been added for example code. A version of SHARP APL/PC has been added which also has additional implementation code examples (requires a DOS emulator in order to run).

Practical Common Lisp
This page, and the pages it links to, contain text of the Common Lisp book Practical Common Lisp published by Apress These pages now contain the final text as it appears in the book. If you find errors in these pages, please send email to book@gigamonkeys.com. These pages will remain online in perpetuity—I hope they will serve as a useful introduction to Common Lisp for folks who are curious about Lisp but maybe not yet curious enough to shell out big bucks for a dead-tree book and a good Common Lisp tutorial for folks who want to get down to real coding right away. However, don't let that stop you from buying the printed version available from Apress at your favorite local or online bookseller. For the complete bookstore browsing experience, you can read the letter to the reader that appears on the back cover of the treeware edition of the book.

About a year ago, my daughter scanned nearly 600 old family photographs, adding captions to them as she went. This was fine as a start but then I was asked for photos of my grandparents’ weddings there was nothing for it but to...
