Hi, I have a dataset which includes information on a person-level for individuals living in different countries. The 'country' variable takes on values such as NL and BE for Netherlands and Belgium, respectively. I need to run the analysis per country, so I limit my regressions to, for instance, the Netherlands.

I would like if the output of my post regressions results incorporate the country for which I did the analysis. For instance, currently (part of my) code is:

margins, at(married=(0 1 ) educ=(0 1 2) hours=(0 1 2)) saving(margins_effort, replace)

Ideally, I would set a parameter at the start of the code, which automatically saves the results in margins_effort_NL instead of margins_effort. I would appreciate any advice on this.

Edit: the goal of course is that when I rerun the analysis for a different country, setting the parameter at the beginning to for instance BE, the file output becomes then margins_effort_BE etc.
