Dear Stata Members, I have to generate interaction variables between a
country dummy and a time variable!

I have a dataset with 50 countries. So using the tabulate command I get 50
dummy variables (country1, country2,....country 50). Now I want to multiply
all these variables for a time variable! In this case I will generate 50 new
variables!

To do that, I can multiply each country dummy for the time variable.

gen cy1=country1*year

gen cy2=country2*years

....

gen cy50=country50*years

I was wondering if there exist any command to make this in a faster way! 

Thanks for your help
