st: Re: Dropping Observations

[momo <mmsabra@gmail.com>]

Anyway thank you, but as I said before in the message if I put 
drop var11 if (var11==var5)

to clarify the problem
I have say a 10000 companies data and each company has (code(var5) total
number of affiliates(var10) and code for each affiliate (var11))

so I need to drop the affiliates that have the same code of the main
company(headquarter))

drop var11 if (var11==var5) or drop var11 if (var11==var5) do not work

I think I have to include something to say "for each company" but how

any idea

thanks
