An output terminal for feedback nodes that mirrors the initializer terminal

[altenbach]

Feedback nodes can reside entirely inside one case of a case structure. This simplifies coding if feedback operations are limited to one single case. Unfortunately, there is no easy way to retain the output once the loop has finished if the last iteration executes one of the other cases. As a result, we might see local variables or even indicators inside the case containing the feedback node, defeating the "in place" purpose. For a "wired" solution, we need to place the feedback node outside the case and wire across all other cases (image top).

I propose an output terminal that sits on the output edge of a loop and contains the contents of the feedback node at the time the loop finishes. Typically that would be the edge of the same loop that contains the initializer terminal (image bottom), but it should also be available for globally initialized feedback nodes and on other loop boundaries surrounding the feedback node (selectable).

I am sure this idea needs to be worked out in more detail, so this is just an initial concept. 😄

Yes, you can right-click the initializer terminal and "show feedback node" to find it.

(maybe the menu item should be called "find feedback node" instead. because it is typically not "hidden" in the classic sense (like e.g. hiding a control), even though it might be in a different case :D)

The answer is yes.

Yes it is in 8.6
