You've declared the array to be ascending sequence, but the debug shows
the actual data to be in descending order.

OK, perhaps the LOOKUP should be a bit more robust and handle the
error more gracefully, but basically, you're lying to RPG.  See what
happens if you code DESCEND on the array definition instead.
