Actionscript Dynamic Variables for object

Question

How can I create dynamic variable in ActionScript?

Example code:

import windows.nwindow;

for(var num:int = 0; num< 2; num++)
            {
                this["nWin"+num] = new nwindow();
                this["nWin"+num].width = 320;
                this["nWin"+num].height = 200;
                this["nWin"+num].title="window" + num;
                this["nWin"+num].open();
            }

When I run the above code it dispatch this error:

Error #1056: Cannot create property nWin0 on MultiWindow.

So, how can I use dynamic variable for this case here?

The answer below is correct, but I'm wondering what is the advantage in your program to having a dynamic member vs. an element in an array. I.e., rather than this["nWin"+num], have this.myWindows[num]? — Bill Turner

you can use a dictionary to achieve this. eg-

        var dict:Dictionary = new Dictionary;
        for(var num:int = 0; num< 2; num++)
        {
            var str:String = "nWin"+num;
            dict[str] = new nwindow();
            dict[str].width = 320;
            dict[str].height = 200;
            dict[str].title="window" + num;
            dict[str].open();
        }

In this case an "Object" would have been enough. Dictionaries are used wherever the key is not a string. If however your key can be mapped to strings I guess an Object should be simpler.
