In that case, Benja's nextID solution works pretty well for me.

I've only been coding in Java for a few months (since I started
playing with GZigZag); I'm afraid I don't understand what you
mean by this.  I assume this is something that could be done
in an applitude without changing the core?

A good example in the existing code is the g/G command available
to the user--currently, if the user types the ID of a cell that doesn't
exist and executes the g command, a new cell is created.  I'd
rather be told that the cell doesn't exist, but now I understand
that GZigZag embodies a different concept of existence than what
I was thinking.  If you're going to expose IDs to the user, you
might think about whether a user would be confused by a new cell being
created just by their attempting to jump to it (well, I was, at least :-).

Thanks,
