7.4 Log formats
The appearance of the log in terms of prefixing the messages is dependent on the used environment. The
most flexible ways of prefixing the messages is given when running Hercules using the WinGUI. Running
Hercules with the native console gives only limited options. The following table show an overview of the
log options, depending on the Hercules version used.

Most of the console command examples in this book are made without the WinGUI and with LOGOPT set
to NOTIMESTAMP as described below. This is to ensure that the sample output from the commands fits
into the text boxes in this book.
7.4.1 Hercules Console
Using Hercules under Linux, Mac OS or Windows (without WinGUI) lets you prefix the console messages
with a timestamp. The difference between these options is shown in the next figure.
Switching the option can be done with the ‘logopt’ console command or can be set at startup time through
the ‘logopt’ system parameter.
Please note that the console itself does not show the timestamp, independent of the ‘logopt’ settings.
Only the hardcopy log does show the timestamp.
