BEGINNER AUTOLISP - LESSON 1 - INTRODUCTION

Lesson 1 of a beginner AutoLISP tutorial series.
Without any prior knowledge of AutoLISP you will be able to code a simple (but useful) AutoLISP program at the end of this tutorial series.

If you are at a more advanced level than these tutorials are designed for, you may still gain a useful tip, insight, or idea for your own code. Individuals with prior knowledge might want to skip to about the 3rd or 4th tutorial.

Hey Great Job! I've been working in lsp since 2005 and didn't know about double clicking the parenthesis!!!! Thanks for teaching this old dog a new trick!

Great Job! I've been even watching Autolisp videos from South Korea to check some practical examples of this programming language. Thanks a lot for what you are doing. 4 Months ago i thought i was an Expert with AutoCAD, but no way! there's a whole universe of programming to discover :)

Very articulate and easy to understand what you're saying. However it seems that there is some info that was left out and it wasn't explained why, for example, the (/) was left out. But I liked how you explained what DEFUN was and you explained the formula much better than most tutorials on YouTube. BTW, Autodesk does not any instruction on lisps other than the community forums, which is no help at all.

I'll bet Emacs is a bit easier to write source code in. There is a slight mismatch between AutoLISP and Emacs Lisp but it should take care of stuff like automatic indentation and closing of your s-expressions. Maybe somebody should write an AutoLISP mode for it...
