st: selecting cases

["Dalhia Mani" <dalhia.mani@gmail.com>]

hi,
How can I select particular cases (e.g. all observations where
var1>100 and var1<200), and run a regression only on those cases?  I
don't want to drop the cases.  I just want to select them for a
particular regression.

Any help will be much appreciated.

thanks so much
dalhia
