I watched the video presentation from Edsge W. Dijkstra. It is very helpful.
I made a typo in my previous e-mail: His first name is Edsger
I am trying to call a function and print a message.
moveEndR :: (IO ()->a) moveEndR = putStrLn"END OF Solution" <<< === THIS IS INCORRECT.
The type signature is wrong, you can find the type of the function with Hugs and GHCi: Prelude> :t putStrLn"END OF Solution" putStrLn"END OF Solution" :: IO () -- Met vriendelijke groet, Henk-Jan van Tuyl -- http://Van.Tuyl.eu/ --
