For information on operators, that do not fall into these categories, see the ActionScript 2.0
Language Reference, which contains information about all the operators you can use.
The following sections show you some common uses for operators. For more information on
using many operators in a single code sample, see
on page 199.
Using operators to manipulate values
Operators are commonly used to manipulate values in Flash. For example, you might want to
create a game in Flash where the score changes depending on the user's interaction with
instances on the Stage. You can use a variable to hold the value and operators to manipulate
the value of the variable.
For example, you might want to increase the value of a variable called
example demonstrates how to use the + (addition) and += (addition assignment) operators to
