Sorry, i'm not clear.
What I mean, is actually not
the modifying. so if I set "0000->str1, the next time its loaded, it should be again "0000 and not "1111 or so.
I hope this is more clear and not ambiguous (is that the right word here?)
EDIT: and, Deep Thought, I've tried that earlier, but that didnt work
EDIT2: nvm, understood it.
