Abstract

L'invention se rapporte à un procédé de correction de programme qui est capable de corriger des erreurs dans un programme de système stocké dans une mémoire morte sans échange de mémoires. Lorsqu'une partie à corriger dans le programme de système comportant des erreurs est introduite manuellement, conjointement à des données correctives (S) contenant une instruction de programme correcte, dans un dispositif à commande numérique par l'intermédiaire d'un clavier, les données correctives sont stockées dans une mémoire rémanente (24). Pendant le processus d'initialisation au moment de la mise sous tension, un processeur (21) fonctionne de façon à transférer le programme de système (P) contenu dans une mémoire morte (22) vers une mémoire à accès sélectif (23) et les données correctives sont écrites dans la partie à corriger du programme de système ainsi transféré. Ainsi les erreurs contenues dans le programme de système peuvent être automatiquement corrigées sans qu'il soit nécessaire de procéder à un échange des mémoires de lecture.
