Ada is a structured, statically typed, imperative, and object-oriented high-level programming language, inspired by Pascal and other languages. It has built-in language support for design by contract (DbC), extremely strong typing, explicit concurrency, tasks, synchronous message passing, protected objects, and non-determinism. Ada improves code safety and maintainability by using the compiler to find errors in favor of runtime errors. Ada is an international technical standard, jointly defined by the International Organization for Standardization (ISO), and the International Electrotechnical Commission (IEC). As of May 2023, the standard, called Ada 2022 informally, is ISO/IEC 8652:2023.
In computing, a compiler is a computer program that translates computer code written in one programming language into another language. The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language to create an executable program.
General Comprehensive Operating System is a family of operating systems oriented toward the 36-bit GE-600 series and Honeywell 6000 series mainframe computers.
The National Institute for Research in Digital Science and Technology (Inria) is a French national research institution focusing on computer science and applied mathematics. It was created under the name French Institute for Research in Computer Science and Automation (IRIA) in 1967 at Rocquencourt near Paris, part of Plan Calcul. Its first site was the historical premises of SHAPE, which is still used as Inria's main headquarters. In 1980, IRIA became INRIA. Since 2011, it has been styled Inria.
The history of programming languages spans from documentation of early mechanical computers to modern tools for software development. Early programming languages were highly specialized, relying on mathematical notation and similarly obscure syntax. Throughout the 20th century, research in compiler theory led to the creation of high-level programming languages, which use a more accessible syntax to communicate instructions.
Le Lisp is a programming language, a dialect of the language Lisp.
Jean David Ichbiah was a French computer scientist and the initial chief designer (1977–1983) of Ada, a general-purpose, strongly typed programming language with certified validated compilers.
LIS was a system implementation programming language designed by Jean Ichbiah, who later designed Ada.
The SDS Sigma series is a series of third generation computers that were introduced by Scientific Data Systems of the United States in 1966. The first machines in the series are the 16-bit Sigma 2 and the 32-bit Sigma 7; the Sigma 7 was the first 32-bit computer released by SDS. At the time, the only competition for the Sigma 7 was the IBM 360.
Bernard S. Greenberg is a programmer and computer scientist, known for his work on Multics and the Lisp machine.
Plan Calcul was a French governmental program to promote a national or European computer industry and associated research and education activities.
The Honeywell Level 6 was a line of 16-bit minicomputers, later upgraded to 32-bit, manufactured by Honeywell, Inc. from the mid 1970s. Honeywell literature for Models 6/06, 6/34 and 6/36 say "Series 60 ". In 1979 the Level 6 was renamed the DPS 6, subsequently DPS 6 Plus and finally DPS 6000.
CP-6 is a discontinued computer operating system, developed by Honeywell, Inc. in 1976, which was a backward-compatible work-alike of the Xerox CP-V, fully rewritten for Honeywell Level/66 hardware. CP-6 was a command line oriented system. A terminal emulator allowed use of PCs as CP-6 terminals.
Alice Recoque was a French computer scientist, computer engineer and computer architecture specialist. She worked on the designs of mini-computers in the 1970s and led research focused on artificial intelligence.
The CII 10070 is a discontinued computer system from the French company CII. It was part of the first series of computers manufactured in the late 1960s under Plan Calcul.
Mistral is an information retrieval system designed and produced by the French company CII in the 1970s, which quickly became known internationally.
Siris 8 is a discontinued operating system developed by the French company CII for its Iris 80 and Mitra 15 computers. It was later replaced by Honeywell DPS 7.
The Iris 50 computer is one of the computers marketed by the French company CII as part of plan Calcul at the end of the 1960s. Designed for the civilian market, it was produced from 1968 to 1975 and was the successor to the CII 10070. Its main competitor in Europe was the IBM 360/50, which, like the Iris 50, was a universal 32 bits mainframe suitable for both business and scientific applications.
The Mitra 15 is a minicomputer made by the French company CII under Plan Calcul, along with the Iris 50 and Iris 80 mainframe computers. It was marketed from 1971 to 1985 and could function in conjunction with large systems. CII manufactured a thousand Mitra 15 machines until 1975 in its Toulouse factory, then in Crolles in the suburbs of Grenoble. A total of 7,929 units were built, most of them for the French market, with a small number sold in Australia, Indonesia, and in other European countries.
