A german autolisp-guru made this interesting project:

The web-based evaluator, or am I missing something..? (note, I'm not german)
Yes, a web-based evaluator.
You can save it to local disk and take a look at the javascript-code.
Not as powerfull as newLISP, because of the javascript limitations.
Yesterday I get very sad news.
Axel Strube-Zettler died on 1.2.2006 through cancer.
(He was the great guy who wrote the pils-interpreter)
The german autolisp-scene has lost a great programmer and supporter.
His various web-site are/were a great resource for autocad-programmers.
