One final data step, adding the maximum of x to each observation:

data addmax;
do until (end1);
   set original (keep=x) end=end1;
   if z < x then z = x;
end;
do until (end2);
   set original end=end2;
   output;
end;
run;

I'm not really sure if this will be faster or slower than the SQL approach.
