Only messages that meet the criteria specified by the TraceFlags property are added to TraceList.  

TraceList is a TStrings descendant. As such, you can use its methods to  

Clear the list. 

Access the individual commands in the list. 

Add your own comments to the list. For example, you may want to indicate when your application initiates certain actions so that you can see clearly what SQL messages correspond to what actions.
