Par défaut se sont des valeurs qui sont passés en paramètre à <a href="fr_subroutine.html" class="wikilink1" title="fr:subroutine">Subroutines</a> et <a href="fr_function.html" class="wikilink1" title="fr:function">Functions</a>. Cela signifie que les valeurs spécifiées à l'appel sont copiée dans les variables correspondantes qui sont entièrement locales à la fonction.<br/>
La déclaration ref permet de passer la référence d'une variable ou d'un tableau à la routine. Quand une routine change la valeur d'une telle variable, les changements sont répercutés dans lavariable originale.
