st: Data set question - going through all observations

["Doron,A (pgt)" <A.Doron@lse.ac.uk>]

Hi,
I'm wondering how to do this. I have 20,000+ records and I need to iterate through them to remove observations where doubl column =1. How would I go about this, I know how to do it with C++ but no idea in Stata. thanks.
