Feedback Nodes in LabVIEW 8.2 vs 8.5

Primary Software: LabVIEW Development Systems>>Base Package
Primary Software Version: 8.2
Primary Software Fixed Version: 8.5
Secondary Software: LabVIEW Development Systems>>Professional Development System

Problem:
Why can't I put down a feedback node on the block diagram in LabVIEW 8.2?

Solution:
In LabVIEW 8.2, feedback nodes need to be placed inside a while loop or for loop. The picture below refers to a feedback node in LabVIEW 8.2 which is initialized to integer value 0.


In LabVIEW 8.5, feedback nodes are able to function without a while loop or for loop. This is advantageous when you must create a subVI using feedback nodes without any loops. The picture below refers to a feedback node in LabVIEW 8.5 which is initialized to integer value 0.
