Adrian, I think that maybe this can help...
you have to use the command "keep (varname1) (varname2)..." and Stata keeps
only the columns (or variables) that you want to work with

Asunto: st: Question on Removing Superfluous Data
Hi !
I'm new to the list, and I had a short question about STATA commands.
I'm working for a professor who's trying to clean up her dataset; she
told me that there was a command in STATA that automatically kept only
the data columns used to produce result (more precisely, a command that
allows one to automatically drop columns not used for a given do file)
-- do you know what this might be?
Thanks,
--
Adrian
