If the index is built on a file with alphabetic characters, Dennis will
have to wait until 5.0 arrives for AIX.  If it's a date, then the trick
is to add a real numeric field (length 5) to the map, and have auto
processing stuff it with the difference between 01/01/NN (where NN is
one greater than PFCMARK) and the real date field that you wanted to
peruse in reverse order.
