Hello all. It's me again :) This time I'd like to ask someone to explain me why this happens. I have this piece of code: test = do writeFile "/tmp/hsout" "first" h <- readFile "/tmp/hsout" writeFile "/tmp/hsout" "second" putStr h So, when i've done this i thought that (putStr h) would print the string "first". But it didn't, it printed the string "second". My question is why? And how can i do to print the first string instead of the first one. Thank you, Jo�o ------------------------------------ geek code inside :: powered by linux
