Setting up a HVar inside a program, IF it doesn't already exist.

[matalog]

Thanks, that does work, but it doesn't allow me to update a non local List Variable, as it may not exist when the program is first Run.

If I wanted to use this method, then I would start by loading the local list variable with the non local one, but that isn't possible as it is potentially not created yet.

Is there a definite way to create a list variable within a program, that doesn't require the program being exited to have the List variable actually created and updatable.

A solution to this would be to run a small prep program before use of the main program, but that isn't user friendly for a new user of the program.
