    Description

    On entry in the method, AData is the AData parameter passed to TThread.ExecuteInThread. ReportStatus is passed to the method, and the threaded procedure can call ReportStatus at various stages to report about the status of the method: The status will be reported to the main thread using TThread.synchronize, so calls to ReportStatus will be blocked as long as the status was not reported.
