Equivalenz of (quote (...)) and '(...)
Hi list, I thought that (quote (...)) and '(...) should be equivalent, but I get different results with the following two versions of a little test program: # version A (prog (let (tab '((1 2 3 ) (4 5 6) (7 8 9))) (+ (caar tab) (caar (cdr tab ) --- result: : -> 5 # version B (prog (let (tab (quote ((1 2 3 ) (4 5 6) (7 8 9 (+ (caar tab) (caar (cdr tab ) --- result: : !? (+ (caar tab) (caar (cdr tab))) (1 2 3) -- Number expected Thats a bit strange - at least for me ;) cheers Thorsten -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
