Data storage and retrieval Omron CJ1

Hi guys.
Can anyone enlighten me on the easiest way to store the last 20 results of test data on a CJ1 for display on a PT.

Assign a 'table', say DM100-Dm119. Increase an indirect address pointer 100-119, and write in. Structured text in an FB will make this a piece of cake.
If you're using an NS screen, a numeral display field can be copied 20 times with increasing address automatically.
Is this what you're after?

Exactly what i need!!

Many thanks.
