Thanks Cynthia.
Since the ouput for my last bit of code is centered and on one single page (what I meant by "back to normal") in 9.2.2, I assume the uncancelled page break and the left justification for the graph in 9.1 has been fixed.
So far, I consider the lack of ability to change justification using proc document a shortcoming, and the ToC not picking up the proc document label for graphs a defect. I think I'll raise these as suggestion and with tech support respectively. What do you think?.
One last question to better understand what proc document can do: can it make use of the ODS PDF layout and region definitions or does it just stack all the replayed outputs?
Thanks again for your patience and insight.
