Pretty much exactly what it says. Now, keep in mind that a "warning" message does not indicate a failure or error. Presumably you successfully read your file into "filedata." What it's saying is that the <EOL> character exists inside some character string in one of the elements of your file. Whether that matters is of course dependent on what your data are and what you're doing with it.
