Als Stahl bezeichnet man heute alle Eisenlegierungen - mit Ausnahme der nicht schmiedbaren hochkohlenstoffhaltigen Gu sorten wie Grauguli, Hartguf und Ternperguf - ohne Riicksichr auf ihre Eigenschaften. Friiher wurde als wesentliches Merkmal des Stahles die Hartbarkeit angesehen. Es gibt aber eine ganze Reihe von Stahlen, die sich nicht harten lassen, die durch das Abschrecken aus hohen Temperaturen im Gegenteil sogar weicher, zaher werden. Edelstdble werden vielfach solche Stahle genannt, die au er mit Kohlenstoff auch noch mit anderen Grundstoffen, z. B. mit Chrom, Nickel, Wolfram, Vanadin usw. legiert sind. Diese Begriffsbestim- mung ist jedoch nicht erschopfend und auch anfechtbar, Denn man wird einen reinen Kohlenstoffstahl, der sorgfaltig erzeugt und auf dem ganzen Wege der Herstellung - vom Gu bis zum Versand - immer wieder gewissenhaft gepriift worden ist, zweifellos auch zu den Edelstahlen rechnen miissen. Andererseits enthalten manchmal Massenstahle - auch als unbeabsichtigte Verunreinigungen - ge- wisse Mengen von Legierungselementen. Das Richtige wird man treffen, wenn man die bei den grofsen Hiittenwerken in grofien Mengen erzeugten billigen Stahle als .Mas- senstahle bezeichnet, die von einem Edelstahlwerk mit Sorgfalt und unter scharfster Kontrolle hergestellten Stahle dagegen als Edelstahle. Die billigen Massenstahle werden meistens nach Festigkeit ver- kauft, die Edelstahle dagegen nach dem Verwendungszweck und unter einer Markenbezeichnung.

Die Absicht, ein Buch iiber Programmieren von Ziffernrechenanlagen zu schreiben, entstand auf Grund einer Vorlesung gleichen Titels, die ich seit nunmehr sieben Jahren an der Technischen Hochschule Wien halte. Ich hatte dabei bemerkt, daB das Interesse fiir die Programmierung von Ziffernrechnern immer weitere Kreise zieht und daB es moglich ist, dieses Interesse aus einem einheitlichen Gesichtswinkel zu befriedigen. Der Zugang zur Kenntnis des Programmierens erfolgt heute iiblicher- weise mit Hille der Mathematischen Verfahrenstechnik oder von seiten der Administrativen Automation, oder schlieBlich iiber die mit tech- nischen Einzelheiten vermengte Beschreibung spezieller Maschinen. Ich bin nun der Meinung, daB man ein Buch iiber Programmieren schreiben kann, ohne auf Einzelheiten der Mathematischen Verfahrenstechnik und der Biiroautomation oder auf technische Eigenschaften spezieller Ma- schinen eingehen zu miissen, und ohne damit jewells einem Tell der Leser das Verstandnis zu erschweren. Was nach Fortlassung der ge- nannten Gebiete bleibt, ist nicht ein trockener, unverstandlicher Rest, sondern der Inbegriff aller fiir das Programmieren wesentlichen Prin- zipien. Sowohl der Naturwissenschaftler als auch der Verwaltungsfach- mann, der diese Prinzipien erfaBt hat, wird jederzeit in der Lage sein, sie seinen besonderen Aufgaben dienstbar zu machen. Kapitel A solI zeigen, welchen Platz der Rechenautomat unter den technischen Errungenschaften einnimmt und wie er dorthin gelangt ist. Besonderes Anliegen ist mir hier der geschichtliche Uberblick, well einer- seits die deutschsprachigen Biicher auf diesem Gebiet kaum historische Angaben enthalten und andererseits die anglo-amerikanische Literatur die kontinentaleuropaische Entwicklung iibergeht. - Kapitel B enthalt die Beschreibung einer gedachten Maschine TElCO in allen Einzelheiten.
