Subject:      Re: Dropping variables efficiently

depends on. If you need that dataset later anywhere a view might be more efficient:

data a / view=a; set b (drop = x y); run;

with that you read b only once. If you first copy the dataset to a and then use it, you have 2 reads and 1 extra write. Gerhard
