Number format Input instruction

Didier and Tim, THANKS for your replays.
Tim, I think you know my problem. I hope you (HP software engineers!) will update this in the next update(s).
Didier, what I meant, if you select at Home settings "engineering" mode the value will be presented as engineering after inputting the value. So entering a value, for instance 1 <enter> it will be presented as 1.000E1. That is of course correct. But running the second time it will be presented as 1 (not as 1.000e1)
I shall try to include a simple program tomorrow (Dutch time!) I don't know how to that yet.
It's for me some times difficult to explain in English, sorry fore that!
I hope you both understand it.
