[Juan M. Duran]

Hi, I am developing a software based on Genetic Programming and I am
trying that this soft makes source code in Haskell. 
I've two problems, one is that I only count on The Haskell report and I
need more information about haskell's available library.
On the other hand, I need to read a file and (as in imperative
programming) get each word the file has because they are parameters for
future functions.

Thanks

Juan

PS: Here is some code I made:

import IO

arch = "twoboxes.dat"
mode = ReadMode

main = do {handler <- openFile arch mode; 
	 contents <- hGetContents handler; 
	 putStr contents; hClose handler }

putList :: a -> [a] -> [a]
putList x [] = [x]
putList x xs = x:xs
