I'm trying to work with lists in Visual Haskell Studio, but it doesn't recognize import Sytem.List neither does it recognize import List. How can I use simple list functios in VHS? Urgent! Thank you so much in advance!!!

A:
Do you mean:
import Data.List
I suggest always using Data.*
for anything in the Data
libraries, rather than regular List
or Ratio

A:
First of all, I will point out that Visual Haskell Studio is an (outdated) IDE plugin, and not an implementation of Haskell itself. I suspect the underlying implementation is GHC.
Second, List is in Data.List, not System.List. If you don't know where a library is, but you know of a function that exists in that library, you can use Hoogle, which appears to be down right now. An alternative you can use while Hoogle is down, is Hayoo.

http://hayoo.info is now live -- nice, short URL :)
