Aside: I thought the story was McCarthy wanted to use M-expressions??

Yes, wasn’t it a student who suggested using s-exprs instead?

According to wikipedia, but I can’t get the ‘AI Memo 8’ to download ftp://publications.ai.mit.edu/ai-publications/pdf/AIM-008.pdf

Works?

IDK maybe I had slow connection when I tried

this just raises more questions. I cant find any reference to M-Expressions (this is why I don’t trust wikipedia), and now I’m trying to understand S-Functions (What!)

how about John McCarthy’s “History of Lisp”? http://jmc.stanford.edu/articles/lisp/lisp.pdf

there’s some discussion there of M-expressions
