Is it possible to build in a file in a haskell program??

[Alexandre Weffort Thenorio]

Yes you are right (I tested with openFile in TextMode) but as far as I can
see openFile cannot be changed to any other mode than TextMode thus openFile
does not work with binary files (.bin) whereas openFileEx can be set to
BinaryMode instead of TextMode which gives me the right output. Thanks for
pointing it out. Why isn't IO and IOExts put together in one library. For
example functions like openFile can be rewritten to work the same way as
openFileEx thus eliminating one function and making it easier for the user
not to have to compile the program with lang package.

Best Regards
