Changing publish settings in flash by writing code

How to change publish settings in flash dynamically by writing code. Is it possible? And how it can be done?:confused:

What exactly are you trying to accomplish that you think dynamically changing publish settings is the solution?

No.Actually i want to change action script type but without using publish settings dialogue box.So how it can be done?

Why would you want to switch actionscript versions in the middle of a program? Being able to do that wouldn't even make sense, everything would fail because it'd be in a different syntax.

I was assuming you meant from AS2 to AS3 or vice versa.
