Search the LabVIEW Help for "Feedback Node" and read the first topic that comes up (it should be called "For Loop and While Loop Structures"). Scroll down almost to the bottom and you'll see a screenshot showing the "feed forward" version of the feedback node. To create one of these, do the following: 1. Drop a function (I used an Increment function because it's easy) in a loop. 2. Wire the output to the input. 3. Branch off the same wire (it should be broken) and wire to the loop border. 4. Right-click anywhere on the broken wire and choose "Insert Feedback Node". Voila...you have the "feed forward" node. That section I referenced in the LabVIEW Help should adequately describe the functionality of a feedback node in this case. -D

Hi Jim, The word "topic" in the documentation you reference is simply a misprint. Replace "topic" in that sentence with "portion" and you'll have the correct description of the '^' character. Sorry for the anticlimactic response...I'll bet you were all ready with a conspiracy theory. -D P.S. - I have filed a CAR (3VLDERF2) against the LV documentation to get this corrected.

I just checked with some of my colleagues in LabVIEW R&D and this is what I found: Static VI Reference issue: This is expected behavior. A Static VI Reference will not appear in the Callees' Names or Callees' Paths property list. This is because a Static VI Reference allows you to have a VI call itself recursively, and the Callees' properties do not support recursive VI calls. I have filed a CAR (3VJDFQF2) against the LabVIEW documentation so we can indicate this fact in the help for both the Static VI Reference and the Callees' properties. SubVI with Required Input issue: This is a bug, and I have filed a CAR (3VJDCQF2) on this issue as well. -D
