Programmatically Change Default Values of Global Variables

Primary Software: LabWindows/CVI Development Systems>>Base Package

Secondary Software: LabVIEW Development Systems>>LabVIEW Full Development System

Problem:
How can I save the default value of a global variable?

Solution:
There is no direct way to do this because a global variable is like a VI, and it saves the values internally. So the VI must be stopped in order to be able to modify it.

A work around is to add an additional delay in the main VI to wait until all of the values are closed, then save the default values using a second VI.

Below is an example of how this is done. Just open the toplevel.vi then the reader.vi to see that the global variables are communicating
