If I have 2 data sets:
data investment;
begin='01JAN1990'd;
end='31DEC2009'd;
run;
data investment_2;
begin='01JAN1990'd;
run;
I wish to write a program that will give me list of all columns that are in investment but not in investment_2. So in this case, the variable 'end'.
How to do this? I dont want to list out the column names using proc contents on eaqch dataset and then manually eyeball it and check for differences.
