Datatype NULL

Almost each programming language has to deal with NULL. NULL means, a variable has no value. This is needed because other programming languages deal with objects and strings and numbers. But ChaosPro only deals with numbers, so ChaosPro does not need NULL.

Due to this, there's no NULL! Each variable has a value, it may be uninitialized, but in this case the value is just random!
