I wrote a HolyC compiler. Why don't you put your Lisp into God's temple.

God says... C:\TAD\Text\QUIX.TXT

f the dark shadows of ignorance that my unhappy constant study of those detestable books of chivalry cast over it. Now I see through their absurdities and deceptions, and it only grieves me that this destruction of my illusions has come so late that it leaves me no time to make some amends by reading other books that might be a light to my soul. Niece, I feel myself at the point of death, and I would fain meet it in such a way as to show that my life has not been so ill that I should leave behind me

I've written a toy Lisp interpreter that eventually evolved into a toy Lisp compiler. It's a gratifying exercise that I'd recommend for every programmer.

If you find that interesting, you should probably take a look at this:

I had fun following along with him. Now, if he (or I can get my shot at it finished) can ever finish working on the byte-code based version!

This is the best beginner project.

Thank you for this link.

why write toy, when you can write a real one in python, check http://hylang.org

Is there some reason why every code segment inside not one but two scrolling frames?

And does anyone else dislike web design that (1) limits the text to a column a third of the page wide, and then (2) because this is too small, requires a horizontal scrollbar on code segments?

For an explanation of a small Lisp interpreter (in Python) that uses sane web design, one might consider Norvig's http://norvig.com/lispy.html
