Global Functions 49
This example shows a significant difference between use of the Boolean() function and the
Boolean class. The
Boolean() function creates a Boolean value, and the Boolean class creates
a Boolean object. Boolean values are compared by value, and Boolean objects are compared by
reference.
// Variables representing Boolean values are compared by value
var a:Boolean = Boolean("a"); // a is true
var b:Boolean = Boolean(1); // b is true
trace(a==b); // true
// Variables representing Boolean objects are compared by reference
var a:Boolean = new Boolean("a"); // a is true
var b:Boolean = new Boolean(1); // b is true
trace(a == b); // false

Deprecated since Flash Player 5. This action was deprecated in favor of the function
statement.

variables do not exist after the script executes.
■ If variables are not declared inside a block ({}) but the action list was executed with a
call() action, the variables are local and expire at the end of the current list.
■ If variables are not declared inside a block and the current action list was not executed
with the call() action, the variables are interpreted as Timeline variables.
