The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Ken,
If your lookup fails, you can still use the n+1 method for adding the next
element to the array.

So I find myself wondering why you'd ever use %lookup? Why search the
array when you can simply add 1 to a number? Not only is adding more
obvious to the person reading the code, it's also much more efficient
for the computer.
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.
