        *First;
	
        data a_need;
          do b = 1 by 1 until (a ne .) ; 
             set a ;
             if a then b = 1;
             output ;
             if b = 1 then a = .;
           end ;
        run ;
	
        *Second;
	
        data a_need ;
          do until (a ne .) ;
           set a;
           if a then b = 0;
           b + 1;
