msgbox(parameter("varaction"))

15. Now run the test. While running it will show 'hello' in the msgbox.

This example show how to declare test parameters and how to access those.

Remember (taken from QTP guide):

You can directly access test parameters only when parameterizing the value of a top-level action input parameter or when specifying the storage location for a top-level output parameter. To use values supplied for test parameters in steps within an action, you must pass the test parameter to the action containing the step.

Alternatively, you can enter the parameter name in the Expert View using the Parameter utility object, in the format: Parameter ("ParameterName").
