The ActionScript Statements

Note that the opening curly brace appears at the end of the first line after parent_syntax.

The substatements of the statement block appear indented two spaces, each on its own

line. The closing curly brace, also on its own line, is flush with the main statement. Sub-

statements within statement blocks should end with a semicolon, but there are no semi-

colons on the lines with curly braces.

The indenting format is simply a convention, not a requirement of legal syntax. This

book adheres to the style used by the Flash ActionScript editor (the Actions panel).

The following format is also valid and common:

parent_syntax

{

substatement1;

substatement2;

substatement3;

}
