As an April fools day joke this year, I posted a VI on LAVA that shows an implementation of a Functional Global that appears to not have any While Loop or For Loop around the Feedback Node. This trick was accomplished by making the While Loop very large (extending beyond the visible region of the Block Diagram) and coloring the loop’s border white
But, now in LabVIEW 8.5 you really can create a Feedback Node that is not owned by any loop! The screenshot below, shows an example of this.
It’s so beautifully simple
