Yeah just as I expected it. It wrote the whole program OK but when it comes to: mybinfile = It just wrote all the weird stuff that you see if you try opening a bin file in notepad. The weird part is that it didn't write the whole thing, just part of it. Is it supposed to be like that?? I did use readfile function to read the bin file, but just in case how to make a handle into a string, for example: basic = "module MyBinFile ( mybinfile ) where\nmybinfile :: String\nmybinfile = \"" do handle <- openFile "mybinfile.hs" WriteMode --File to be written to hand <- readfile "file.bin" hPutStrLn handle (basic ++ hand ++ "\"") That's what I did basically and I only used readFile to read the bin file because hPutStrLn requires a String and openFile gives me a Handle so is it possible to make a handle to a String?? Also what am I doing wrogn because apparently I am not getting stuff like /x01/x02 but weird stuf like: DÅÍo in the created file.

Thanks but I am not sure what exactly you mean. I've done this: [..] Tried compiling main.hs file but it says "Failed to load interface for MyBinFile".

This means you haven't compiled MyBinFile.

Do you know about Haskell modules? You should read the relevant section of the Haskell Report (www.haskell.org/onlinereport/), and also the documentation of your compiler.
