For Problem 4 of Project Euler How do I break out a loop?

var largest=0
for(i<-999 to 1 by -1) {
    for (j<-i to 1 by -1) {
        val product=i*j
        if (largest>product)
            // I want to break out here
        else if(product.toString=product.toString.reverse)
            largest=largest max product
    }
}

And does anyone know how to turn nested for loops into tail recursion?
