You can use monitor to view binary log files (.mon files). However, it may sometimes be necessary to create a plain text copy of the log file so that it can be viewed in other applications.
Whilst you can save the current screen log to a text file at any time, this can be potentially problematic if a very large number of records have been displayed. Even if the procedure to convert a binary log to a text log is complex, it ensures that no records are lost.
