Thank you David. I'd seen that part without really reading it nor
understanding what it means. In particular, how does it explain that
"setpos()" doesn't set the column if and only if the current column is
"infinite", whereas it works ok otherwise?

To put it another way, if "setpos()" is half useless, why does it
exit to begin with?

Best,
Paul
