Trihedralguy has asked for the wisdom of the Perl Monks concerning the following question:

I was wondering how I go about doing a simple if statement like this:

if ($value == "blank") { Do this } else { Do that };

Where blank would be how to check if the variable has nothing in it. I tried doing NULL, 'NULL' and '', but that doesnt work?

Edit: g0n - code tags
