Problems with 'readFile'

[Alexandre Weffort Thenorio]

Hi. Well I have no idea which is the ASCII character 26 but remember that it
will stop if it encounters a EOF character (Although that doesn't seem to be
the case). Why don't you try Openfile to see if it gives same error??

Something like:

main = do let output = problemtext
      putStr output
      putStr "\n\n"
      writeFile "outputfile.txt" output
          text <- openFile "outputfile.txt" ReadMode
          y <- hGetContents text

      PutStr y


If problem persists you could use the IOExts Library (I believe that it is
only found in ghc) and read it in binary mode.
Something like:

Import IOExts

main = do let output = problemtext
      putStr output
      putStr "\n\n"
      writeFile "outputfile.txt" output
          text <- openFileEx "outputfile.txt" (BinaryMode ReadMode)
          y <- hGetContents text

      PutStr y

Remember to use lang package in case you compile it. Let us know how you get
on.

Best Regards
