its not only about strings, but also integers and other classes.

However I figured out it is not the best method to use a direct pointer to the value I want to set.

First I wanna to change a var directly, but I think its a better approach for me to use 2 procs, 1 get, 1 set. (however I still use pointers).
Its needed cause I may need to do some more actions when I set a var to a new value.

(it's a bit hard to explain, but I hope you can understand )
