I'm sorry, but I still don't know what you're trying to say. Perhaps you could write it in your native language and use google translate.

If you are asking whether you can assign the value of one variable to another, then yes, of course you can.
Code:
var another:String = obj;
But be aware of when you do that assignment. In the code you just posted, the variable another will have the value "varhi". I don't think that's what you want.
