Saad, at first I thought the problem was you put a space after the single-quote mark. I tried what you entered using the Beginning Student with List Abbreviations language, and it worked, space or no space:
> '((1 3 5 7 9) (2 4 6 8 0)) (list (list 1 3 5 7 9) (list 2 4 6 8 0)) > ' ((1 3 5 7 9) (2 4 6 8 0)) (list (list 1 3 5 7 9) (list 2 4 6 8 0)) Then I tried with the Beginning Student Language, and I got what you got: '((1 3 5 7 9) (2 4 6 8 0)) quote: expected the name of the symbol after the quote, but found a part Then I thought, "Better look at Realm of Racket." On page 21, the page before page 22, it says that for the immediately following examples, you should pick "The Racket Language" (not Beginning Student Language).

In the first pages it asks one to download Racket which I already have but in the BSL mode. When using it I type in the following in the interactions panel as advised by Realm of Racket to see about lists (page 22): ' ((1 3 5 7 9) (2 4 6 8 0)) the message I get is: quote: expected the name of the symbol after the quote, but found a part It does not return the list as it is supposed to in the book. Is this because I am using BSL? If so what should I do/ Thank you for any help. Saad ____________________ Racket Users list: [1]http://lists.racket-lang.org/users -- Geoffrey S.
