I am wondering if there is a more efficient way to append a bunch of data sets during read in. Fortunately, all the data sets I am working with follow the same naming convention and only differ in a single number that increments each year. I have been doing the below, but since is this something I will simply have to add to each year, am wondering if there is a way to use a macro (indicating the most recent year) and a loop to make this more efficient.
data app_data; set ds2015 ds2016 ds2017 ds2018 ds2019 ds2020; *Other stuff happens; run;
