Comments can be any length without affecting the size of the exported file, and they do not need
to follow rules for ActionScript syntax or keywords.
To create a comment block, place
This technique lets you create lengthy comments without adding // at the beginning of each line.
By placing large chunks of script in a comment block, called commenting out a portion of your
script, you can test specific parts of a script. For example, when the following script runs, none of
the code in the comment block is executed:
// The following code runs
var x:Number = 15;
var y:Number = 20;
// The following code doesn't run
/*
// create new Date object
var myDate:Date = new Date();
var currentMonth:Number = myDate.getMonth();
// convert month number to month name
var monthName:String = calcMonth(currentMonth);
var year:Number = myDate.getFullYear();
var currentDate:Number = myDate.getDate();}
*/
// The code below runs
var name:String = "My name is";
var age:Number = 20;
Keywords and reserved words
ActionScript reserves words for specific use within the language, so you can't use them
as identifiers, such as variable, function, or label names. The following table lists all
ActionScript keywords:

if
instanceof
