{   This procedure is used for the task end cleanup of operator messages.
{ When a task terminates this procedure checks to see if there are any
{ messages posted to the operator for this task.  If there is a message
{ then the message will be marked as cancelled. This is to let the operator
{ know that the message was sent to the operator but the originating
{ task is no longer in the system.
