Topic: How to substitute some item in different depth list

[qjchen]

Thank you all. I will try my best to learn recursion. It is said that it is useful for "fractal" in math.
I was told that recursion is the basic of Lisp, according to 7 basic function, it define almost all the other function, Many basic functions are defined by recursion, I wonder whether AutoLisp can use this basic function, like atom, car ... to define all the function which big Lisp, such as Common Lisp own.
But when I learn Lisp, the "let" "dotime" always make me confuse, can they be define by the basic AutoLisp function.

I will try my best to learn recursion.

Some time back, I have started to write lessons about recursive functions...
" Lessons of the creation of the recursive functions "
 Has published ten lessons!

Thanks, I am reading the nice Lesson.
babelfish is a good website, the translation quality is rather good.
but when I reading page 41-60, the transltation get wrong, I dont know why, does any translation site can do it, it seems that google translation cant do it.
OK, I get it

and I remind the pages which concern about the "Fractall" use autoLisp

Thanks for sharing your good work.

I badly know the English tongue... 
Otherwise I would translate lessons and have published on theswamp.org!
