I’m confused and hoping someone can point me in the right directions.  
I have a class myClass with a getRandomLetter function that returns a String.  
It uses \_model.lettersArray[rp.getNum()]; to get a random letter from an array. the function checks if this new letter is the same value as an unchanging value corLetter. if this value is the same i want a new random letter to be generated and returned. But then i need to check that new letter. but i can’t think of how to do it without causing a recursive loop. Please see code below

l

```auto
etter1:String = myClass.getRandomLetter();

public function getRandomLetter(): String
        {
            newLetter = _model.lettersArray[rp.getNum()];
            var corLetter:String = _model._correctLetter.toLowerCase();

            if(newLetter.toLowerCase() == corLetter)
            {
            newLetter = _model.lettersArray[rp.getNum()];
            }

            return newLetter;
        }

```

thanks in advance for any help
