IguN,
1. Create a VI that takes as an input parameter the TestStand sequence context.
2. Use a property node to obtain a reference to the FileGlobals (run-time copy) of the currently executing sequence file.
3. USe an invoke node to call the PropertyObject.NewSubpropety method.
I am attaching a sequence file that uses a LabVIEW step to create a file global.
I used TestStand 3.5 and LabVIEW 7.1.
The sequence only contains two steps. The first step asks for the new variable name and the second calls the VI that creates the new file global.
In order to see the new variable created you have to pause in the breakpoint, click on the globals tab and expand the FileGlobals branch.
To learn more about lifetime and scope of file global variables refere to the TestStand help.
Hope it helps.
Best Regards.
Antonio Lie
