Understood. But this is Statalist. If anyone posts Stata code that looks
wrong, don't be surprised if someone points that out. If you know your
code is rough, or regard it as pseudocode, please say so.

program. I was rewriting the example to better illustrate my point
and didn't actually run the program. Sorry if there was any confusion.
