If in the end you do need to merge the datasets together to run your
analysis and you cannot 'save' them, your best option is to save each
separate dataset as a tempfile (see tempfile) and merge these together
in active memory. All tempfiles are eliminated when a Stata session is
closed, so I imagine this would be legal for you to do.

Subject: st: RE: how to use multiple datasets?
How about if you -append- the datasets and run the regression for each
country one at a time?
Alternatively you can use -foreach- to loop through the datasets and do
the
regressions.
