How can I check that a variable has been declared? I know using Option<BR>Explicit will throw an error if a variable hasn&#039t been declared but this<BR>isn&#039t what I need. I&#039ve tried using isEmpty but that will only tell me if a<BR>variable has been declared and is empty. I need to check whether a variable<BR>has been declared and if it hasn&#039t, then declare it.<BR><BR>Many Thanks<BR>J-P<BR><BR>P.S. I have played around with Cold Fusion a little, this has a tag called CFPARAM, if anyone has come across it, this is the sort of functionality I am looking for.<BR>
