Line break in the dialog box

The CR string (Carriage Return) can be used to force a break to the next line. For example:
Confirm("The XXX form was modified." + CR + ...
"Do you want to save it before exiting?")
is equivalent to:
Confirm("The XXX form was modified.", ...
"Do you want to save it before exiting?")
You also have the ability to use the syntax of multiline strings. For example:
Confirm(
[
The XXX form has been modified.
 
DO you want TO save changes before closing?
])
