Statements

Statements are language elements that perform or specify an action. For example, the return statement returns a result as a value of the function in which it executes. The if statement evaluates a condition to determine the next action that should be taken. The switch statement creates a branching structure for ActionScript statements.

Statements summary

Statement	Description
break	Appears within a loop (`for` , `for..in`, `do..while` or `while`) or within a block of statements associated with a particular case within a `switch` statement.
case	Defines a condition for the `switch` statement.
class	Defines a custom class, which lets you instantiate objects that share methods and properties that you define.
continue	Jumps past all remaining statements in the innermost loop and starts the next iteration of the loop as if control had passed through to the end of the loop normally.
default	Defines the default case for a `switch` statement.
delete	Destroys the object reference specified by the reference parameter, and returns `true` if the reference is successfully deleted; `false` otherwise.
do..while	Similar to a `while` loop, except that the statements are executed once before the initial evaluation of the condition.
dynamic	Specifies that objects based on the specified class can add and access dynamic properties at runtime.
else	Specifies the statements to run if the condition in the `if` statement returns `false`.
else if	Evaluates a condition and specifies the statements to run if the condition in the initial `if` statement returns `false`.
extends	Defines a class that is a subclass of another class; the latter is the superclass.
for	Evaluates the init (initialize) expression once and then starts a looping sequence.
for..in	Iterates over the properties of an object or elements in an array and executes the statement for each property or element.
function	Comprises a set of statements that you define to perform a certain task.
get	Permits implicit getting of properties associated with objects based on classes you have defined in external class files.
if	Evaluates a condition to determine the next action in a SWF file.
implements	Specifies that a class must define all the methods declared in the interface (or interfaces) being implemented.
import	Lets you access classes without specifying their fully qualified names.
interface	Defines an interface.
intrinsic	Allows compile-time type checking of previously defined classes.
private	Specifies that a variable or function is available only to the class that declares or defines it or to subclasses of that class.
public	Specifies that a variable or function is available to any caller.
return	Specifies the value returned by a function.
set	Permits implicit setting of properties associated with objects based on classes you have defined in external class files.
set variable	Assigns a value to a variable.
static	Specifies that a variable or function is created only once per class rather than being created in every object based on that class.
super	Invokes the superclass' version of a method or constructor.
switch	Creates a branching structure for ActionScript statements.
throw	Generates, or throws , an error that can be handled, or caught , by a `catch{}` code block.
try..catch..finally	Enclose a block of code in which an error can occur, and then respond to the error.
var	Used to declare local or Timeline variables.
while	Evaluates a condition and if the condition evaluates to `true` , runs a statement or series of statements before looping back to evaluate the condition again.
with	Lets you specify an object (such as a movie clip) with the object parameter and evaluate expressions and actions inside that object with the statement(s) parameter.
