Die bisher aufgetretenen Grundbegriffe lassen sich folgendermaßen zusammenfassen: Nachrichten haben Träger und Form; durch Interpretation gewinnt man aus ihnen Informationen. Sie werden in der Informatik durch Algorithmen verarbeitet. Ein Al gorithmus ist ein spezieller Typ von Nachricht. Er ist syntaktisch exakt beschrieben in einer Befehlssprache, deren Semantik auf eine Struktur von Operationen auf Mengen von Werten von Objekten abbildet. Die Befehlssprache wird auf unterster Sprache bene durch Ausführung interpretiert, während sie auf höherer Sprachebene in eine primitivere Sprache übersetzt wird. Semantik und Syntax der Befehlssprache müssen wegen der maschinellen Übersetzung und Interpretation regelhaft formuliert sein. Deshalb werden im Kapitel 4 formale Sprachen exakter eingeführt und genauer untersucht. Dabei wird die Rolle von meta sprachlichen Algorithmen zur Festlegung von Syntax und Semantik einer formalen Sprache deutlich. Deshalb kann man formale Sprachen, auch wenn sie nicht Befehls sprachen sind, nur unter Benutzung von Algorithmen beschreiben. Der Algorithmus begriff führt also zurück zu den formalen Sprachen und diese wiederum lassen sich nur mit Algorithmen (in Metasprache) darstellen. Das Vorgehen im Kapitel 4 wird vermutlich dem Leser etwas übertrieben abstrakt vor kommen. Der Grund ist, daß absolute Exaktheit in formalen Konstruktionen geübt werden soll. Zu exakten Konstruktionen in der Informatik benötigt man natürlich auch Grundelemente der exakten Wissenschaft par excellence, nämlich der Mathe matik. Dies wird hier aber lediglich als eine Erweiterung der Metasprache um ei nige hilfreiche Begriffskonstruktionen aufgefaßt. Deshalb werden die mathematischen Grundbegriffe im Kapitel 3 kurz zusammengestellt; dieses kann von mathematisch ausreichend vorgebildeten Lesern übersprungen werden.

This volume is being published for two reasons. The first is to present a collection of previously published articles on the subject of programming methodology that have helped define the field and give it direction. It is hoped that the scientist in the field will find the volume useful as a reference, while the scientist in neighboring fields will find it useful in seriously acquainting himself with important ideas in programming methodology. The advanced student can also study it-either in a course or by himself -in order to learn significant material that may not appear in texts for some time. The second reason for this volume is to make public the nature and work on programming methodology of IFIP Working Group 2.3, hereafter called WG2.3. (IFIP stands for International Federation for Information Processing.) WG2.3 is one of many IFIP Working Groups that have been established to provide international forums for discussion of ideas in various areas. Generally, these groups publish proceedings of some of their meetings and occasionally they sponsor a larger conference that persons outside a group can attend. WG2.3 has been something of a maverick in this respect. From the beginning the group has shunned paperwork, reports, meetings, and the like. This has meant less pUblicity for IFIP and WG2.3, but on the other hand it has meant that meetings could be devoted almost wholly to scientific discussions.
