[Haskell-cafe] the "interact" function and Hugs/ghci on Windows ...

Hello, I have a Haskell script that contains several functions that are implemented in terms on "interact". When I do a "function application", Hugs/ghci is waiting for input from stdin. How do one denote EOF from stdin, so that the function evaluation can continue and do the IO () action , ie.. write to stdout? Regards, Vasili
