158 Chapter 5: ActionScript Core Language Elements

The following example uses for to perform the same action repeatedly. In the code, the for loop

adds the numbers from 1 to 100.

var sum:Number = 0;

for (var i:Number = 1; i<=100; i++) {

sum += i;

}

trace(sum); // output: 5050

The following example shows that curly braces ({}) are not necessary if only one statement will

execute:

var sum:Number = 0;

for (var i:Number = 1; i<=100; i++)

sum += i;

trace(sum); // output: 5050
