Jack, that was the point I was making - although, as others have pointed
out to me, the _n_=0 method may be slightly clearer to third parties - in
the sense that it is perhaps then even more clear than anything following
the THEN must have a significance (if any) BEFORE the first iteration of
the DATA step (when _n_ = 1 from the very start).

Kind Regards


John
