An extra restriction is that, although a variable identify can have digits, the 1st character of a variable title can't be a digit.

In the course of an object’s lifetime, further references to it might be developed, while you noticed previously mentioned, and references to it could be deleted likewise. An item Resources stays alive, since it ended up, As long as There is certainly no less than a person reference to it.
