That way the same servlet can dig the documents out of the database and return them to the client and the urls can be permanent so Google might give his pages a decent sco

14:35 jonrafkind: the 2 is in the procedure application part
14:35 jonrafkind: its (<procedure> <argument 1> <argument 2> ...)
14:35 jonrafkind: what did you want? a list of (2 3 6 9) ?
14:35 jonrafkind: try '(2 3 6 9) or (list 2 3 6 9)
14:36 Danny78: I'm taking a list and checking if 2 is a member of the list
14:37 Danny78: I have a function, mem, (define mem (lambda( x l) ...
14:38 Danny78: and (mem(2 numbers)) gives that error
14:38 jonrafkind: so you want a list of numbers
14:38 jonrafkind: try my suggestions
14:39 Danny78: I can't use "list" but I can use cons, and I created a list:  (define numbers(cons 2 '(3 6 9 )))
14:40 jonrafkind: ok that works
14:40 jonrafkind: but why cant you use list?
14:40 Danny78: this is hw for an online class (don't know anyone around here so I'm here to figure out why I can't pass numbers as a variable without errors)
14:41 jonrafkind: ok cons is fine
14:41 Danny78: if I use (define numbers(cons 2 '(3 6 9 ))) and then call  mem(2 numbers), I get that error
14:43 jonrafkind: so dont do that
14:43 jonrafkind: (mem numbers)
14:43 Danny78: Scheme is completely new to me and I read all the materials for the class but mem is the procedure and 2 and numbers are the arguments, so shouldn't it be  (mem(2 numbers))?
14:43 jonrafkind: (mem 2 numbers)
14:44 jonrafkind: you have an extra parentheses there
14:46 Danny78: wow, ok awesome, thanks!  I should have known--  it was parentheses before.  Prof is in a bad mood (online instructors seem to be a particularly moody sort) so thanks much

18:48 jonrafkind: the stuff you put in match, (match foo [(list a b c)])
18:48 jonrafkind: (match foo [(list (my-a) (my-b))]) you can define (my-a) that will expand into some other match expression
18:48 jonrafkind: basically im saying you can use match as an adhoc parser
