in thread variables not posting?

Line 2: The semicolon is an alternate delimeter. An agent submits data using that and your code breaks. Of course, since you can't guarantee that the data in $temp isn't corrupt...

I'd like to see some evidence.

Of the various good arguments for using CGI.pm, this one has always struck me as the weakest. The use of a semicolon as an argument delimeter is so effectively deprecated as to be non-existent. When is the last time you heard of any agent using a semicolon as a delimeter (other than a hand-rolled agent whose purpose is to demonstrate that it can be done)? What browsers use a semicolon?

I know of a few public web-based systems that have run for years without encountering a semicolon used as a parameter delimeter. Is that proof that such a thing can never happen? No. Are these systems at risk? No, unless some practical joker decides to hand-roll a request.

    It's the opposite of deprecated. It's intended to be supported in the future, so if you don't start supporting it now, browsers which use it in the future will break your code.

      Do I detect the faint scent of some large corporation sneaking this into some specification to guarantee the future obsolescence of everyone else's software? :-(

        No, it's just that the ampersand was a bad choice to use, but the original designers of cgi were doing the best they could. :)
