What Is a Variable?

A variable is a “container” for storing data. Variables store information such as numbers, text, or references to an object or another variable (Figure 2.1). In order to work with any type of data or object instance in ActionScript, the information is stored in, or referenced by, a variable. Every object or piece of information in ActionScript is a variable at its core.
