Assune the find sub is called with $_ equal to SomeFile.html, but that file does not exist. The routine as written simply returns, and the user is left to wonder why nothing was displayed. I'm suggesting that a message be displayed explaining why nothing was displayed. The reason I suggested the name of the file be passed in a global variable (e.g. `$path`) is because $_ is used internally by Perl for a number of reasons. To prevent the path from being clobbered, it should be explicitly stored.	[reply] [d/l]
