Lesson 1: User Created Variable Names
The first step in creating a user variable is to select a name for it.
This name can be as simple as the letter X, or several lines long. It
must follow these simple rules:
* It must start with either an alphabetic or an underbar character.
* It must contain only alphanumeric or underbar characters; nothing
else.
* It can be from 1 to 255 characters long.
* It can have no spaces.
