Line break in the dialog box

The CR string (Carriage Return) can be used to force a break to the next line. For example:

YesNo("La fiche XXX a été modifiée." + CR + ...
"Voulez-vous la sauver avant de quitter?")

is equivalent to:

YesNo("La fiche XXX a été modifiée.", ...
"Voulez-vous la sauver avant de quitter?")

YesNo(
[
La fiche XXX À été modifiée.

Voulez-vous la sauver avant de quitter?
])
