QMF Visionary enables you to capture user information (or other information, such as a query result) and pass it to other parts of your world with parameters. A parameter is a value given to a variable in an operation or an expression before it is executed by the world.

You can use parameters in many ways. Event actions typically capture user input in a parameter. You can use global and scene parameters when you design interactive controls in your scenes; when a user makes a selection in the control, an underlying event action sets the parameter value. The parameter value determines what data is displayed or how it is displayed.
QMF Visionary provides three types of parameters:
