Re: Adding array elements...

Ken,
If your lookup fails, you can still use the n+1 method for adding the next 
element to the array.

Another consideration, which I don't think would be a concern for this
specific situation, but definitely applies when thinking about the
concept in general ...

If your lookup value is a valid array element value, you can overwrite
an element.  The +1 method eliminates this possibility.
