For each?

long ExtObject::cForEachThing(LPVAL params)
{
    if(things.size() == 0)
        return false; //no things, no for each

    currentThing++;

    //reset counter if at end
    if(currentThing == things.end());
        currentThing = things.begin();

    return true;
}
[/code:vo7952n6]
and then an expression to retrieve data from currentThing. Doesn't this just get called once per frame, when I want to go through each object on every frame?

extObj::cMyfunction(lpval PARAMS)
{
    for(int i =0; i < keys.length; i++)
    {
        currentKey = keys[i]
    }

}

in your expression ace

extObj::eReturnCurrentKey(Lpval params)
{
    return currentKey;
}

somthing like that I think would be how its done
