You shouldn't have to flush output manually. Which implementation are
you using? Try importing System.IO and doing:
hGetBuffering stdout >>= print
and see what gets printed. It should be "NoBuffering". If for whatever
reason it's not, you can set it to that at the start of your programs
with
hSetBuffering stdout NoBuffering
If it's still NoBuffering, check that your terminal isn't doing
something strange.
hope this helps,

Hi all,
I'm working through the "Haskell for C programmers" tutorial and in this section":
http://www.haskell.org/~pairwise/intro/section3.html#part7
has:
main = do putStr "prompt 1" a <- getLine putStr "prompt 2" b <- getLine putStrLn (show (someFunc (read a) (read b)))
which I believe needs a:
hFlush stdout
after each "putStr" line and an "import System.IO" at the top of the file.
