Re: st: a question about -if- command

["Katsuhide Isa" <CQB01114@nifty.ne.jp>]

To Ulrich and Nick:

Thank you for your advice.
Thanks to the explanation by Ulrich and the FAQ page
Nick suggested, I understand the foundamental difference 
between if-qualifier and if-command.
If it's a feature in Stata, I think I have to follow it.

K.I.
