OK Guys. First I would like to say thanks for all the help given before. As I said I am still learning Haskell. My problem is the following: I have a text file and somewhere in the file there is string (Let's say aaaa). So I need to find this exact string and overwrite with another string (Lets say bbbb). I have thought a bit and couldn't find any solution, and I believe it is a piece of cake for some of you. Is there a method already implemented in haskell to do that?? Anyway thanks in advance.

QuickCheck is in de "util" package. You can load a package with the -package flag:
$ ghci -package util Prelude> :browse QuickCheck class Arbitrary a where { arbitrary :: Gen a; coarbitrary :: forall b. a -> Gen b -> Gen b; } arbitrary :: forall a. (Arbitrary a) => Gen a ... Prelude>:module QuickCheck
Prelude QuickCheck> :info trivial -- trivial is a variable trivial :: forall a. (Testable a) => Bool -> a -> Property
Hope this helps.
Cheers,
Arthur

Can anyone help me figure out how to load QuickCheck into GHCI? QuickCheck is included in my Debian package, but my attempts at loading it are bootless:
Prelude> :load QuickCheck can't find module `QuickCheck' Prelude> :load util/QuickCheck can't find module `util/QuickCheck' Prelude> :info syntax: `:i <thing-you-want-info-about>' Prelude> :load util/QuickCheck.hi can't find module `util/QuickCheck.hi' Prelude> :load /usr/lib/ghc-5.02.2/imports/util/QuickCheck.hi can't find module `/usr/lib/ghc-5.02.2/imports/util/QuickCheck.hi' Prelude> :load /usr/lib/ghc-5.02.2/imports/util/QuickCheck can't find module `/usr/lib/ghc-5.02.2/imports/util/QuickCheck' Prelude>
Any advice, anyone?
