It's the OS that tells you through the EOF "character" that you have reached the end of stream. What do you use to read the file (you only said how you open it)? If you use getc() or fgetc(), you can check if the character is EOF. Then you will know you've reached the end. t. --------------------------------------------------------------------------- Tony Porczyk * tporczyk@netcom.com * San Jose, California GIT/ED d++$(!d) s++:++ a?
