Lisp 101

Would anyone be kind and patient enough to give me an overview of how a lisp is structured? I have copied a few and was successful to make it work but there are some instances that a few of them did not then a friend of mine mentioned about possible ommision of sort in the program itself.

I have not gone throughout the forums' list if there are lisp written to determine the total length and area of multiple and independent lines or polylines which normally is important in site design, and if you already have these, may i copy them?

I look forward to hear from you guys. Thank you.

I would love to explain exactly how a LISP is structured, but there are some great tutorials on the net that explain things a lot better than I ever could,

Lee Mac,

I have just browsed the websites quickly and very excited of how they will definitely help me in my work.

Right now, I'm a little lost in cad world because I don't get enough help from our "guru" in the office for favoring another (so much of the drama) BUT since I joined this forum a couple of days ago it feels like I've learned so much (and empowered) with the help I get from you and lpseifert plus from a few people whose postings are very insightful.

Thank you but remember this will not be the last time I may need your help guys. Thank you, thank you...

No worries, we're all pretty happy to help

If you have any other questions, just ask

The best way to learn is to write it yourself and then post the code and questions when you run into a problem.

Autocad has a great tutorial for lisp that was install with you acad called garden path.

You should do the tutorial and write each line your self and you will learn a ton.

It covers the basics to advances programming using reactors.

Be a programmer not a copier, I have seen a lot of post here wanting routines but they don’t want to put the effort into learning anything. I get paid for writing programs and I don’t mind helping out a newbie or an advanced programmer stuck in a corner as long as they learn something.

I appreciate your concern and I do intend to learn it. I also agree that by writing your own is the best way to learn how the program works. Look forward to hear questions from me and I will count on everyone here who are patient enough to indulge me from learning the trade. Thanks!
