how to pass all the values of a table to a macro

[kumarK]

i have a macro it will take input as a country and will give its population.

Then i have another table list of all countries. I want to pass all these countries to that macro.

I tried below way i declared all the countries in a global variable and passed that variable

% let countries=india nepal......;

This is not a efficient way. how can i pass all the values of another table in to that macro. Please throw some inputs.

proc sort data=have(keep=country) out=country nodupkey;by country;run;

data _null_;

set country;

call execute('%mymacro(country=' ||country|| ')' );

run;
