Comparing Something with Nothing

[BobHamburger]

One of the many cool things which I love about LabVIEW is the ability of most of its primitives to be polymorphic. Similar to the general meaning in Computer Science, polymorphism is a programming language feature that allows values of different data types to be handled using a uniform interface. For example, the comparison palette is almost completely generic; you can use the same equality or inequality primitives for integers, floats, strings, enums, or arbitrarily complex compound structures (e.g. clusters) comprising all of the aforementioned. Particularly handy is LabVIEW's capacity to be polymorphic with arrays, which in many cases eliminates the need for looping. However, with this convenience comes behavior which may or may not suit your needs.
