; Displaying exception information from an event
: If a command produces events that contain errors, you may want to display the details of the exception information related to particular event in a nicely formatted way, analogically to what the <code>error?</code> (shortened: <code>er?</code>) command does. To do so, determine the index ''eventIndex'' of the event in the sequence, and then enter the following command: <code>events? ''eventIndex'' --!extractMember EventArgs.ErrorDescendInfos</code> (shortened: <code>ev? ''eventIndex'' -!xm EventArgs.ErrorDescendInfos</code>). The resulting table starts with a row for the outmost exception, and the subsequent row(s) contain the inner exception(s), recursively. An error ID and the full error message is listed with each exception.
