If one has 50 countries in an international survey with 1000 respondents per country, what is the most efficient way to show the distinct correlation between two variables for each of the 50 countries?  Must one go to select if, and give the country code for each country separately?  Or can one somehow control for country number and show the (partial?) correlations for each country in one command?

Thanks

You can do SPLIT FILES on the country and get either one table with everything in it or 50 separate tables.  You might want to think about some graphics to go with that.
