Question

I have a data set sorted by x1 and x2. For every value of x1 I want to only print the last value of x2. How do I do this? Would it be something like:

if last.x2 then print;

Answer 1

Itzy was close, but the LAST statement needs to be changed to refer to X1, like in the following:

data tmp;
 set mydataset;
 by x1 x2;
 if last.x1;
run;

proc print data=tmp; run;
