A problem with scheme syntax

[Cronox1]

I'm using DrScheme and wanted to see can anyone figure out why when i give certain forms im given weird errors even when they should not be there for instance I give

(car '(123 245))
and I get the error
quote: expected a name after a ', found something else

or ill give

(list 'a)
and instead of getting (a) back i get
(cons 'a empty)

Thanks for any help.

(a)

works fine here, what scheme implementation are you using? (mine is mzscheme, btw)

He's using DrScheme :)

By the way,

(cons 'a empty)


is identical to


(a)


I believe

DrScheme provides different languages; you're using a more elementary language that doesn't include the " 'expr " syntax shortcut. If you're far enough along in Scheme to understand the things you should see, you should turn down the learner-ishness of it :)
