If you've ever done list processing, CONTROLLED storage is the cat's
meow. Beats the Dickens out of trying to maintain arrays and array
counters, especially if there's a chance of exceeding the size of the
arrays. ...
How is CONTROLLED preferable to BASED? Certinly not if you
need to delete arbitrary list elements, since (I just RTFM)
CONTROLLED is strictly LIFO.
---------------------------<unsnip>---------------------------
In order to do proper list processing, you need to define the elements
CONTROLLED BASED(..). But the original question was about CONTROLLED.
