L'instruction DELETE supprime les enregistrements du stockage de masse. Certains compilateurs permettent d'utiliser l'instruction DELETE avec une clause FILE pour supprimer les noms FD (ainsi que toute structure d'indexation associée pouvant être requise par le moteur de gestion de base de données utilisé).
