Notice when input data:

Ÿ Pressing DT DT can input the same data twice.

Ÿ Using SHIFT ; you can input the same data time after time. For example, if you want to input 20 and 30

five times, you can press 20 , 30 SHIFT ; 5 DT .

Ÿ The above result can be required in arbitrary order not necessarily in the above order.

Ÿ If you need to delete the just inputting data, you can press SHIFT CL.
