Get instance in scene by IID?

I have to select a couple of instances in the scene that I have to remove.

I've saved their IID but I don't know how to select and destroy them by script (Evensheet).

Is there an example somewhere? I've seen that by script you can pick objects like this:

myObject(IID).destroy but I can't find a why to do it in an eventsheet.

Set an instance variable on the object to the IID then pick object compare instance variable object.var
