Nevertheless, the code quoted below _is_ incorrect.  The code "works" only
insofar as it runs without an error message, even when the open() fails and
the program has no input - which sounds suspiciously like the problem Ken

I suppose you can continue to carelessly copy the mistakes of your Perl
books, but eventually it might be useful to actually learn Perl.
