Usually, such a problem occurs with some (usually complex) program that I wrote quite a long time ago.

But if no line ending can be found, then the file simply has one single line. i can't understand your question. if the problem is that the system doesn't magically produce a variable called line_number, then generate it yourself, by counting in the loop. Don't forget that you can tell the unicode decoder to ignore bad characters, or to convert them to a specified placeholder. -- DaveA
