 ===== Description ===== ===== Description =====
  
-This functor initiates and feedbacks ​a loop variable ​containing ​a kml timeline.+Initializes ​a loop variable ​and feeds it back with the KML timeline produced by the previous step, letting ​a KML timeline ​carry over from one iteration of a loop to the next. At the start of the first iteration, it reads its initial value from Initial. The use of this functor is central to building dynamic models whose variables are updated from one step to the next through feedback.

 +===== Notes =====
 +
 +This functor must always be placed directly inside a loop container, such as [[Repeat]], [[For]], or [[For Each Category]]. Placing it anywhere else reports a warning.
 +
 +Feedback should be connected to a functor evaluated later in the same iteration, so that it can supply the value produced by that step. Setting it to a fixed constant reports a warning, since a constant defeats the purpose of feeding a value back from the previous step.
