Set Value for Internal Variables (Itern) during Runtime

Set Value for Internal Variables (Itern) during Runtime

Hi,
I've been trying to set the value of a internal variable during Runtime but was not successful.
In the end, I checked that ReadOnly returns true. It is not possible to change the value of a internal variable during Runtime?
Please help me.
Thanks.
