| - | This functor makes a map dynamic, feeding it back with a map output from a model step. In the beginning of the first iteration, it reads map input from the initial port. | + | Initializes a loop variable and feeds it back with the map produced by the previous step, letting a map carry over from one iteration of a loop to the next. At the start of the first iteration, it reads its initial map 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. |

| - | The use of this functor is critical for the development of dynamic models whose map variables are dynamically updated as a result of the model feedback. | + | 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. |
| - | <WRAP center round box 80%> | + | Feedback should be connected to a functor evaluated later in the same iteration, so that it can supply the map produced by that step. Setting it to a fixed constant reports a warning, since a constant defeats the purpose of feeding a map back from the previous step. |
