lisp. any suggestions on learning?

Hey all, this might not be the best place to ask but I know several of you are fluent in lisp. I need to learn it, should I just pick up a book (if so which one).

The question is really where to begin for someone who has never learned a programming language. Thanks for any input.

Jeff

oh... if it matters our office is currently running ACA 2009. We have 2010 but not running any projects on it currently.

Did you install the AutoLISP tutorial when you installed the program? I am not certain that is part of the default installation. I would suggest doing the tutorial as a reasonable starting point. I am afraid that the last AutoLISP book I bought was for Release 11, so I am not going to be much use on recommending a book. (I also still have the printed manual for AutoLISP from Release 12.) The Help files also are worth having a look through. There should still be a section that discusses groups of commands with similar purposes, which is quite helpful when deciding which one you want.

I would also recommend learning to use the VLIDE (Visual LISP Integrated Development Environment, or something like that). Back when I had more time for LISP programming, I used to use a text editor and then tried to debug by loading the routine and see what happened. The VLIDE will help you by letting you format your file with the click of a button, check matching parentheses and run the program to a designated stopping point and then step through line-by-line while watching variable values to determine the location of a problem.

Thanks David, I didn't even think of the tutorial. I have been using CAD so long without ever venturing into lisp I didn't even realize that there was a tutorial...

I would suggest avoiding the tutorial (sorry David).
As a fellow alisp learner I found the tutorial the most rediculous bunch of
hooha I've ever read.
You type a whole heap of not understandable stuff to accomplish a simple
task and no explaination of the multiple lines you just laboroursly typed.
I learnt NOTHING from that tut except how badly someone can stuff a tutorial
up. It only demonstrates that not everyone is a teacher.

Go register at AUGI and search the AutoLISP NG. At the top are some great
links to downloadable alisp tutorials which start with the basics and work
thru in a logical fashion and have helped me write some basic lisp routines.
Also just google and you will get some good results.

You may be correct - I did the tutorial around the time I bought that Release 11 book, so that was before any of the VLISP functions were available (or the VLIDE). I probably got more out of the book (which I do not believe I ever worked all of the way through, either). I should also point out that I took several computer programming classes in college (using PL/C and Fortran), so I was already familiar with the basics of programming (linear programming, anyway), and only needed to understand the specifics of AutoLISP.

Online training is another option. If you are interested, please contact me.
