During the running of a script, the status bar at the bottom of the main window displays dynamically updated information about the progress of the running task.
In many cases, scripts only take a few seconds to run, so you might not notice this, but for longer tasks, it is useful to watch the progress.
If the script is a test, some of the summary statistics are displayed in the fields on the right side of the status bar while the test is running. Which stats are displayed can be customized using the results script.
The vertical bar character "|" in the formatting codes indicate that a results item should be displayed dynamically in the status bar while a test is running. By default only ROR and MaxDD are displayed.
