What does this ($|=1;) do? It's on the second line of a guestbook script, and I'm thinking it makes variables act differently than they would without it, because in another script for a survey (that doesn't contain this line) I'm trying to duplicate what happens in the guestbook script but it doesn't work. (Writing link on HTML page) The only difference I've found so far is this line. I searched for it in the documentation and CPAN and didn't find anything. Sorry if this is a stupid question.
Thanks,
Dean
