I have just started trying to learn Haskell again (I seem to have a mental block against this language). Right now I'm using Haskell in 5 steps. I have created the file hello.hs exactly as in the section "Write your first Haskell program". I then opened a cmd (I'm using Windows) window in the directory where I created hello.hs and entered "ghc -o hello hello.hs". What follows is the output of the cmd window: hello.hs:1:7: Not in scope: data constructor `PutStrLn' Can someone tell me why I am having this problem? Regards Chris Saunders
