How to use screener to select RICs from multiple countries?

Hello.

Normally if we wish to select RICs from a single country, we could use the screener expression like: SCREEN(U(IN(Equity(active,public,primary))),IN(TR.ExchangeCountryCode,"FR"), CURN=USD)

However, how do we modify the above screener expression to specify a list of countries?

Thank you.
