To create multiple lines with TITLE the "\n" newline escape character can be used to separate the lines.
For example, the following command added to the ruledeck:
TITLE "This is the ruledeck title\nLine 2 is here.\nLine 3 is here."
Will result in the following output in the generated summary report and results database:
This is the ruledeck title
Line 2 is here.
Line 3 is here.
NOTE: The entire TITLE string within double quotes needs to be on the same line. Adding carriage returns within the string will return an error.
