line feeding in Haskell

[S.D.Meshveliani]

I am sorry for asking such a primitive question:

how to make Haskell to feed a line ?


Say, under the HUGS dialogue, we have

? "ab\ncd" 
ab
cd
?


In Haskell  (ghc-0.25)  I tried    

main =  print     "ab\ncd"
main =  writeFile "result" "ab\ncd" exit done

and obtained   ab\ncd


Thanks in advance.

S.M.
