Good points. I'm not a SAS user, so I'll concede my original complaint.

Is it also the case in SAS that if you say something like

regress y x if age > 40

you also get the missing cases on age included? That is the main other thing I dislike about Stata's handling of MD, although it is easy enough to work around so long as you are careful.

Mostly, though, if Stat/Transfer gets better at handling MD conversions, I'll be happy.
