How to get ascii value of character in haskell?

Question

Just wondering how to get ascii value of character in haskell? I've tried to use the 'ord' function in ghci, based on what i read here:

http://haskell.org/ghc/docs/6.12.2/html/libraries/base-4.2.0.1/Data-Char.html#6

GHCi, version 6.12.1: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
Prelude> ord 'a'

<interactive>:1:0: Not in scope: `ord'
Prelude>

What am i doing wrong?

As Travis Brown indicated in a comment, you have to import the ord function from the module Data.Char:

import Data.Char (ord)

main = print (ord 'a')

Only the Prelude module is loaded by default, all other modules have to be imported explicitly.
