I continue to get mail, so I might as well continue to continue...

Why is it called the "top of stack" if the stack grows down?

Yes, the stack grows towards low memory.  The entire problem is that
of terminology.  I wasn't wrong.  No one else was either.  I knew exactly
what I was talking about even if no one else did.

So quit with the mail!!!!!
