[flexcoders] Passing Parameters, is something like this possible with Flex?

[flexnubslice]

Instead of posting a ton of :

if( Application.application.parameters.x)
                     this.x= Application.application.parameters.x;

if( Application.application.parameters.y)
                     this.y= Application.application.parameters.y;

... ad nauseam ...  I was wondering if it was possible to do something
like this?

var elements:Array = [ "a", "b", "c" ];

for( var i:String in elements ){
     if( Application.application.parameters.i )
         this.i = Application.application.parameters.i;
}

I'm not too certain of the language constructs here being new to Flex, 
help greatly appreciated!  The  highlighted line, it does not like.

Thanks!
