Abstract

Die Erfindung betrifft ein Verfahren zur Änderung des Ablaufs eines in einem Festwertspeicher abgelegten Programms. Das Programm weist dazu eine Vielzahl von Programmroutinen auf, und jeder Programmroutine ist ein Unterprogramm, das in einem ersten Schreib-/Lese-Speicher abgelegt ist, zuordenbar. Jeder Programmroutine sind weiterhin Speicherstellen eines zweiten Schreib-/Lese-Speichers zugeordnet. Eine Programmroutine ruft dann, falls dieser Programmroutine ein Unterprogramm zugeordnet ist, das Unterprogramm abhängig vom Inhalt der zugeordneten Speicherstellen auf.
