Pacbase
IBM VisualAge Pacbase is a code-switching structured programming language that is developed and maintained by IBM. VisualAge Pacbase runs on both IBM and non-IBM mainframes and integrates with IBM WebSphere Studio Application Developer. When compiling Pacbase code it is first translated into COBOL and then compiled to binary. PACBASE was an early advanced CASE software for mainframes and Unix systems from CGI (Compagnie Générale d'Informatique, a French software house) that supported a wide variety of databases, including DB2 and Oracle. PACBASE generated COBOL code for the servers, and Visual Age for PACBASE was used to create the client side. IBM purchased CGI in the early 1990s and absorbed the code-generating tools into its other offerings. Pacbase is now considered a legacy system; its main remaining use is in Francophone French became an international language in the Middle Ages, when the power of the Kingdom of France made it the second international language, a ...

IBM VisualAge
VisualAge is a family of computer integrated development environments from IBM, which supports multiple programming languages. VisualAge was first released in October 1993 and was discontinued April 30, 2007 and its web page removed in September 2011. VisualAge was also marketed as VisualAge Smalltalk, and in 2005, Instantiations, Inc. acquired the worldwide rights to this product. IBM has stated that XL C/C++ is the followup product to VisualAge. Early history VisualAge was created in the IBM development lab in Research Triangle Park, North Carolina, which was established in 1984 and had responsibility for application development tools. The EZ-VU dialog manager product, a personal computer derivative of the user interface elements of the ISPF 327x product was one of the first products in this family. The lab also had a group which was one of the early adopters of object-oriented programming technologies within IBM using an internally developed language called ClassC to develop ...

Code-switching (software)
In linguistics, code-switching or language alternation occurs when a speaker alternates between two or more languages, or language varieties, in the context of a single conversation or situation. Code-switching is different from plurilingualism in that plurilingualism refers to the ability of an individual to use multiple languages, while code-switching is the act of using multiple languages together. Multilinguals (speakers of more than one language) sometimes use elements of multiple languages when conversing with each other. Thus, code-switching is the use of more than one linguistic variety in a manner consistent with the syntax and phonology of each variety. Code-switching may happen between sentences, sentence fragments, words, or individual morphemes (in synthetic languages). However, some linguists consider the borrowing of words or morphemes from another language to be different from other types of code-switching. There are many ways in which code-switching is employe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structured Programming
Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of the structured control flow constructs of selection ( if/then/else) and repetition ( while and for), block structures, and subroutines. It emerged in the late 1950s with the appearance of the ALGOL 58 and ALGOL 60 programming languages, with the latter including support for block structures. Contributing factors to its popularity and widespread acceptance, at first in academia and later among practitioners, include the discovery of what is now known as the structured program theorem in 1966, and the publication of the influential "Go To Statement Considered Harmful" open letter in 1968 by Dutch computer scientist Edsger W. Dijkstra, who coined the term "structured programming". Structured programming is most frequently used with deviations that allow for clearer programs in some particular cases, such as when exceptio ...

Programming Language
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning), which are usually defined by a formal language. Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. Definitions There are many considerations when defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM Mainframe
IBM mainframes are large computer systems produced by IBM since 1952. During the 1960s and 1970s, IBM dominated the large computer market. Current mainframe computers in IBM's line of business computers are developments of the basic design of the IBM System/360. First and second generation From 1952 into the late 1960s, IBM manufactured and marketed several large computer models, known as the IBM 700/7000 series. The first-generation 700s were based on vacuum tubes, while the later, second-generation 7000s used transistors. These machines established IBM's dominance in electronic data processing ("EDP"). IBM had two model categories: one (701, 704, 709, 7030, 7090, 7094, 7040, 7044) for engineering and scientific use, and one (702, 705, 705-II, 705-III, 7080, 7070, 7072, 7074, 7010) for commercial or data processing use. The two categories, scientific and commercial, generally used common peripherals but had completely different instruction sets, and there were incompatibiliti ...

Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less b ...

COBOL
COBOL (; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. However, due to its declining popularity and the retirement of experienced COBOL programmers, programs are being migrated to new platforms, rewritten in modern languages or replaced with software packages. Most programming in COBOL is now purely to maintain existing applications; however, many large financial institutions were still developing new systems in COBOL as late as 2006. COBOL was designed in 1959 by CODASYL and was partly based on the programming language FLOW-MATIC designed by Grace Hopper. It was created as part ...

Legacy System
In computing, a legacy system is an old method, technology, computer system, or application program, "of, relating to, or being a previous or outdated computer system", yet still in use. Often referencing a system as "legacy" means that it paved the way for the standards that would follow it. This can also imply that the system is out of date or in need of replacement. Legacy code is old computer source code that is no longer supported on the standard hardware and environments, and is a codebase that is in some respect obsolete or supporting something obsolete. Legacy code may be written in programming languages, use frameworks and external libraries, or use architecture and patterns that are no longer considered modern, increasing the mental burden and ramp-up time for software engineers who work on the codebase. Legacy code may have zero or insufficient automated tests, making refactoring dangerous and likely to introduce bugs. Long-lived code is susceptible to software rot, ...

Francophone
French became an international language in the Middle Ages, when the power of the Kingdom of France made it the second international language, alongside Latin. This status continued to grow into the 18th century, by which time French was the language of European diplomacy and international relations. According to the 2022 report of the Organisation internationale de la Francophonie (OIF), 409 million people speak French. The OIF states that despite a decline in the number of learners of French in Europe, the overall number of speakers is rising, largely because of its presence in African countries: of the 212 million who use French daily, 54.7% are living in Africa. The OIF figures have been contested as being inflated due to the methodology used and its overly broad definition of the word francophone. According to the authors of a 2017 book on the world distribution of the French language, a credible estimate of the number of "francophones réels" (real francophones), that ...
