In general, you don't have to worry about it, because: 1. If a file handle goes out of scope, the file will be closed. 2. If you reuse a file handle that is open by opening another file, the first open file will be closed. 3. You can try to close the file handle regardless of whether it is open or not and ignore any error that the close returns. 4. If you really need to know, check out the eof function (perldoc -f eof). -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
