Sometimes you know based on runtime logic (that the compiler can't know) that some parts of the worst case call tree are impossible. You had better know what you're doing, but in very memory limited cases you could possibly make use of this. I agree this is a unusual corner case. I was responding to your statement more on theoretical grounds than practical ones. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
