You can specify user-named parameters as arguments to the SendUserEvent method defined for the GhostExec class. To do so, you can specify, at the time a userevent is triggered, which arguments in the target frame's userevent activation block declaration will be set with values from the frame sending the event. You can choose from any of the supported OpenROAD 4GL data types, and pass as many arguments as you want from the source frame to the event target.

This support for user-named parameters supplements the existing support for the predefined attributes MessageFloat, MessageInteger, MessageObject, and MessageVarchar.
