TV

Retrieves the value of an event variable in which that value can contain other grammar elements.

This function can be used to expand an event variable textually, that is, with no assumptions about the structure or data-type of the contained value. This function can be useful in cases where the expanded value contains other grammar elements that must be further evaluated, for example, to share common expressions, expression elements, or groups of functions.

See "Pre-parser Functions" in the Guide to the Application Event System.
