	while (loopcond)
	{
		flag = FALSE;
		for (i=0; i<limit; i++)
		{
			if (frob(i))
			{
				flag = TRUE;
				break;

	}

You don't have to spin your wheels in a for loop and you don't have to use
the goto.  I should think if you can avoid a goto, do it.  Some people
believe gotos are inherently not "nice and CLEAN!!!".  But as you say, this
is an old chestnut.
