Get nth value of a variable

It is another idea to get nth value of a variable.

proc sort data=sashelp.class out=tmp(keep=weight) 
     nodupkey;
  by descending weight;
run;

data _null_;
  set tmp end=end;

  retain weight_10th .;
  if _n_ <= 10 then do;
    weight_10th = weight;
  end;

  if end then put "The 10th weight is " weight_10th=;
run;
