# add

#### Availability

Flash Player 4.

#### Usage

    string1 add string2

#### Parameters

`string1, string2` A string.

#### Returns

Nothing.

#### Description

Operator; concatenates (combines) two or more strings. The `add` operator replaces the Flash 4 add (`&`) operator; Flash Player 4 files using the `&` operator are automatically converted to use the `add` operator for string concatenation when brought into the Flash 5 authoring environment. However, the `add` operator is deprecated in Flash Player 5, and Macromedia recommends that you use the `+` operator when creating content for Flash Player 5 or later. Use the `add` operator to concatenate strings if you are creating content for Flash Player 4 or earlier versions of the player.
