I'm coming from a easier languages than C. In .NET, Java or JavaScript I would call that thing a variable (or a constant if it's declared as such). In those languages, if I declare that token, without explicitly giving it a value then the value will be whatever default is, i.e. 0 for numbers, false for booleans, null for reference types etc.
What I want is to declare the token that I would use to access the instance of CommandHandler as global, but only instantiate the object in the setup() method.
What's the correct name for that token?
