Event-List
This property specifies a list of events that may or may not be fired depending on the value of the Exclude-Event-List property. The property requires a sequence of numeric values. It’s suggested that you use the constant values defined in the isgui.def copybook. Multiple values must be enclosed between parenthesis and separated by a space.
