Displays the queue of messages queued with the macro Queue_Out. Normally the queued messages are viewed with the ".S" command so it is possible to see the messages interspersed with the fault information to get a better idea of the execution sequence, but occasionally it is nice to be able to look at the messages quickly to determine if the desired one ever occurred. This list also displays the fault entry index of when each were logged, so it is possible to search for a desired message and then use the ".S" command and specify the identified index as a list starting point.
