I am 99.9% sure that if you make up a new variable name in the property
system and reference it from your dialog, it will be automatically created.
The property system is designed so a referenced property name will be
automatically created if it doesn't exist yet. You just have to be aware
that the variable isn't necessarily created when FlightGear first starts up,
it is created when it is first referenced (which might be when the dialog
box is opened.)

Curt.
