Maybe we could have achieved this level of sessions if we had fewer people
running everything from within HPDesk...or if we'd bought SPLash! All of
our terminal io from native mode programs go through a CM switch to
SPL/assembler routines Jeff Kell wrote long ago.  However, if we'd done
that, we probably still have the 960 and not the 969/120.:-)

IIRC, PDQ is CM, but in it at least a batch report would mostly stay in CM
(or is it OCTCOMPed?).
