I think the "How Not to Ask a Question" link is almost a little bit unsuitable in this case because the OP asked a clear question but seems to have been confused by online tutorials that cover PHP rather than Perl.

I don't see why since Bruce32903 spent about 20 minutes trying to get it to work.... and then he doesn't show his code.

The fragment posted was an excerpt from the documentation Bruce32903 needs to read
