How are you generating the data file? Can't you output a specific character before each EOL char so you can search for it? If you're generating your own file, can't you use serialization? (Or am I confusing that with Java, forgot which does that.) Hal -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
