(')are different from quote
« on: July 15, 2020, 02:25:14 AM »
Code - Auto/Visual Lisp: [Select]
  1. (setq BB (quote(nil (princ 8 )))
    returns a table (nil (princ 8 ))

Code - Auto/Visual Lisp: [Select]
  1. (setq BB ('(nil (princ 8 ))))  
       returns the result 8

After compilation, decompilation, (setq BB (quote(nil (princ 8 ))) becomes (setq BB '(nil (princ 8 ))), with one parenthesis missing

First nil isn't a function so any results would be wrong, second your
Code: [Select]
(setq BB (quote(nil (princ 8 ))))was missing a closing parenthesis.

Lee Mac has a very good comparison of these on his site: http://www.lee-mac.com/quote.html
