AutoLISP Online-Tutorials

As mentioned in my AutoLISP-Intro for Beginners be aware first that there is an AutoCAD Developer Reference for AutoLISP that you find among the help files that come with your AutoCAD installation. Beyond that the following links might be of interest.

General AutoLISP and the "old" DCL:
AutoLISP Learning Series
The first of a series of 14 lessons on AutoLISP published by Autodesk. This is another tutorial than the one in the help file.

AfraLisp.net
A whole lot of tutorials and infos on AutoLISP, the "old" DCL and more by Kenny Ramage & David Watson (incl. a nice tutorial focused on ActiveX - Kenny calls it "Visual Lisp Tutorials"). This site offers a lot of valuable knowledge and is written very well. (In case the AfraLisp.net site gets display incorrectly in FireFox 3.5 or higher then look here.)

The ABC's of AutoLISP
A book on AutoLISP by George Omura (-> here an interview with him) as a website. The book was originally published in 1990. So it's really old. But it certainly covers the very basics and might be of interest for the one or the other reader.

Special Subjects:
Getting Started with DCL Dialogs
Tutorial on the "old" DCL hosted by the AutoLISP Exchange website

OpenDCL - the new and better DCL !should know!
OpenDCL is NOT an integral part of AutoLISP or AutoCAD. You have to download it from this third party website and intall it separatly. It works only from AutoCAD 2004 upward. Good thing: it is free! Everything is explained on their website. It's really well done. Check it out.

The Visual LISP Developers Bible
"Visual LISP Development with AutoCAD 2004" - An advanced tutorial with special focus on ActiveX by David M. Stein; (The AutoLISP basics are NOT covered in here but other tutorials may have some info on ActiveX.)
