problem with some of their tuts is that they really aren’t using the Actionscript 2.0 model. Most of them don’t use strong datatyping…

ie to create a string variable would be:

var mystr:String = new String(); // empty string

they simply do this:

var mystr;

just something I noticed while I was doing some tuts on their site and reading others on the dev center at [macromedia.com](http://macromedia.com)

Yeah, but that’s one of the reasons why MX 2004 is good - you can use strictly typed variables when you want. It doesn’t require you to use them ( if you’re working in a large project, you probably should, but otherwise… )

actually its one of the reasons why it is bad (it lets you do it)… say you created a function and you are using AS 2.0 and there is a portion of that function that relies on a number and you pass it a string? If you are using the old model the string will get added to the number…

ie:  
// this script executes and does not throw an error  
var x = 5;  
var y;  
y = x+“this”;  
trace(y);

// this script throws you an error saying that the types are incompatible  
var a:Number = 5;  
var b:Number;  
b = a+“this”;  
trace(b);
