Thank you so much, Luca.
Mmm... I want to make a "List of Sentence" from some text file.
inputFile.txt is like this.
--------------------------------
This is a pen.
Is this a pen?
etc...many sentence. Each line, only one sentence.
How can I make a list of sentence?
How can I declared inpStr?
Thank you.
Sincerely, Sok Chang

Hello, everyone.
Hello, I don't understand very well what you're trying to do in your code, but if it is simply reading from a file and put the output into another file there is a better way:
import System.IO import System.Random
sentenceAry = []
main :: IO () main = do inh <- openFile "c:\\Documents and Settings\\shaegis\\inputFile.txt" ReadMode outh <- openFile "c:\\Documents and Settings\\shaegis\\outputFile.txt" WriteMode mainloop inh outh hClose inh hClose outh
mainloop :: Handle -> Handle -> IO () mainloop inh outh = do ineof <- hIsEOF inh if ineof then return () else do inpStr <- hGetLine inh hPutStrLn outh inpStr mainloop inh outh
I hope I've understood the problem.. In your code 'inpStr' wasn't in scope, because you've declared it only into else block..
