how to fix my do loop duplicates

[HitmonTran]

Hi, 

I am creating a table shell using do loops; however, it is creating a duplicate to the last records per param.  Please help me fix this duplicate.

data shell;
	 do ord1= 1 to 5; 
		do ord2= 5 ,6 ,7 ,8 ,9 ,12 ,13 ,15 ,16 ,19;
		output;
		end;
	 output;
	 end;
run;

If you don't want the last value written twice then remove the second OUTPUT statement.
