The value variable always has a global scope and is designed to work with FACs so that the variable assignments can be quickly changed. One application of the value variables is to allow multiple call applications to be quickly switched from one operational mode to another. Such a rapid switch over capability can be useful for businesses whose operations are impacted by unpredictable events. For example, a public utility can desire a switch over capacity to respond to widespread power outages associated with severe weather events.

To set up a value variable to use in multiple vectors to meet such a special switch over need, you can administer both a value variable and an associated FAC, as described in the related topics.
