I'm trying to learn Scheme from the book "The Little Schemer" using DrScheme on a Macintosh. It starts with things like "What is the car of l where l is the argument (a b c)?"
I understand that the answer to this question is a, but I'm not able to actually figure out what to type into Dr Scheme to "follow along". A simple idea on how to assign to l such as > (def l ('a 'b 'c))
gives me the error: "function call: expected a defined name or a primitive operation name after an open parenthesis, but found something else"
