Ali has already shown this is a one-step solution.  What I'd add to his
code is a check to ensure that the program correctly handles cases
where the input dataset has fewer than 10 observations.  This is shown
below:

data b;
  do i = n-9 to n;
    if i > 0 then do;
       set a nobs=n point=i;
       output;
       end;
  end;
  stop;
run;
