data test (keep=decimals value displayed);
   do i = 1 to 5;
      do decimals = 0 to 3;
         value = ranuni(95605) * 10;
         displayed = value;
         output;
      end;
   end;
   stop;

proc report data=test nowindows missing nocenter;
   columns value decimals displayed;
   define _all_ / display;
   compute displayed;
      call define(_col_, 'format', '10.' || put(decimals, z1.0));
