Sorry Charles - I have to completely disagree with you here.
Unless you are performing set updates - not that common - most
business applications still process a retrieved set a row at a time.
Whether that be by retrieving the entire set as an array and then
walking through it, or by using a cursor, or ...
Why can the OAR handler not retrieve the set and then hand it back a
row at a time in response to read requests?
I know it will happen becuase the IBM Lab Services team already do
this with SPECIAL files as part of their database modernization
approach. OAR handlers are a natural and much simpler extension of
that process.

While you could certainly do it, I doubt it would be a good idea.
The problem is that ROA is designed for RLA and you'd probably need to
use SQL in the handler to access the remote DB. While SQL can
certainly return 1 record at a time, it wouldn't be very efficient.
