Let's consider a code like this:
DATA temp (drop=month);
DO month=1 to 10;
Since there is a data set inside, we have multiple iterations of the data
I was wondering, how did the data set option drop= do in this code?
My guess is like this:
at the end of EACH data step iteration, the value of the variable month in
the PDV would not be written to the data set temp.
Is this understanding right? Thanks a lot.
