st: FE over two columns

[tazz_ben <tazz_ben@wsu.edu>]

This is probably a stupid question that can easily be done within Stata.
So I have a  gravity model with two columns containing the country names
(obviously).  I want to apply country fixed effects: which means the index
of the FE model is over two columns (ie. a country specific dummy should
be set to one regardless of whether it appears in column one or column
two).

I only have about 50 countries, so I can easily do this manually with
excel then push it into stata; but I thought I should learn how to do this
if Stata can do it internally.

Thanks!

Ben
