Setting Clone Variables

If I have 4 cloned actors how do I set their variables?
eg
actor.1.myState = ON;
actor.2.myState = ON;
actor.3.myState = ON;
actor.4.myState = ON;
Is there a way to set them all at once?
eg actor.myState = ON;

actor.1.myState = ON;
actor.2.myState = ON;
actor.3.myState = ON;
actor.4.myState = ON;
