Say what you mean and mean what you say. As I delve deeper into the world of LabVIEW abstraction and SOLID code development, it becomes increasingly clear that language makes a big difference. We LabVIEW developers might recall some LVOOP primer where the presenter whipped out the old automobile class hierarchy example to convey the idea of inheritance (I'm guilty). It's an example simple enough to build a consensus of nods and let everyone leave the room clearly understanding that a car is indeed an automobile. In spite of its complete irrelevance to the code we write on a daily basis, I think there are a couple of reasons this is actually a useful example.
