Hi there, I am learning a macro program. I am confused about multiple operators. I don't know how SAS evaluates %if comparisons with two operators, one is "(&brand. = Flase)", the other is ">=.". the result of this program returned "Brand is General Electric". may I know why? how to decompose multiple operators? . %macro corpare_brand(brand); %if ((&brand. = Flase) >=. ) %then %put Brand is General Electric; %else %put Brand is &brand; %mend; %corpare_brand(Coke) thanks!
