I need to compare the value of two variables, both of them in character format. Like following example:
data X; set Y;
As you see, I have two variable, Surv_city and city, in dataset Y, and I just want to keep those observations with the same name of Surv_city and city.However, A problem comes up and the result is zero observation. I think the problem occurs because the names of the city are not in the same form of uppercase and lowercase. How can I fixed this problem?
I greatly appreciate any suggestion.
