Rapira
: ''Rapira is also a name for the Soviet 100 mm anti-tank gun T-12 Rapira (russian: Рапира, rapier) is an educational procedural programming language developed in the Soviet Union and implemented on the Agat computer, PDP-11 clones (Electronika, DVK, BK series), and Intel 8080 and Zilog Z80 clones (Korvet). It is interpreted with a dynamic type system and high level constructions. The language originally had a Russian-based set of reserved words (keywords), but English and Romanian were added later. It was considered more elegant and easier to use than Pascal implementations of the time. Rapira was used to teach computer programming in Soviet schools. The integrated development environment included a text editor and a debugger. Sample program: ПРОЦ СТАРТ() ВЫВОД: 'Привет, мир!!!' КОН ПРОЦ The same, but using the English lexics ic, from the article referenced below proc start() output: 'Hello, world!!!'; end proc Rapira's ...

100 Mm Anti-tank Gun T-12
2A19 or T-12 was a revolutionary Soviet 100-mm anti-tank gun. It was the first (anti-) tank gun to adopt a smoothbore barrel, and to introduce modern armor piercing shot, like the APFSDS. It uses long projectiles that are more powerful than its caliber suggests. The T-12 served as the primary towed anti-tank artillery in the Soviet and Bulgarian armies from the early 1960s to the late 1980s. History The T-12 was designed by the construction bureau of the Yurga Machine-Building Plant as a replacement for the BS-3 100 mm gun. The first serial examples were produced in 1955, but the T-12 entered service only in 1961. Its special feature was the use of a smoothbore gun. The T-12 was typically deployed in the anti-tank units of armored and motor rifle regiments to protect flanks against counter-attacks during rapid advances. In 1971 a new variant was introduced, T-12A or MT-12 "Rapira" (2A29). This has the same barrel, but has a redesigned carriage and gun shield. This allows ...

Andrey Ershov
Andrey Petrovich Yershov (russian: Андре́й Петро́вич Ершо́в; 19 April 1931, Moscow – 8 December 1988, Moscow) was a Soviet computer scientist, notable as a pioneer in systems programming and programming language research. Donald Knuth considers him to have independently co-discovered the idea of hashing with linear probing. He also created one of the first algorithms for compiling arithmetic expressions. He was responsible for the languages ''ALPHA'' and ''Rapira'', the first Soviet time-sharing system ''AIST-0'', electronic publishing system ''RUBIN'', and a multiprocessing workstation ''MRAMOR''. He also was the initiator of developing the ''Computer Bank of the Russian Language'' ( Машинный Фонд Русского Языка), the Soviet project for creating a large representative Russian corpus, a project in the 1980s comparable to the Bank of English and British National Corpus. The Russian National Corpus created by the Russian Academy o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-English-based Programming Languages
Non-English-based programming languages are programming languages that do not use keywords taken from or inspired by English vocabulary. Prevalence of English-based programming languages The use of the English language in the inspiration for the choice of elements, in particular for keywords in computer programming languages and code libraries, represents a significant trend in the history of language design. According to the HOPL online database of languages, out of the 8,500+ programming languages recorded, roughly 2,400 of them were developed in the United States, 600 in the United Kingdom, 160 in Canada, and 75 in Australia. Thus, over a third of all programming languages have been developed in countries where English is the primary language. This does not take into account the usage share of each programming language, situations where a language was developed in a non-English-speaking country but used English to appeal to an international audience (see the case of Python ...

High-level Programming Language
In computer science, a high-level programming language is a programming language with strong Abstraction (computer science), abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language ''elements'', be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program simpler and more understandable than when using a lower-level language. The amount of abstraction provided defines how "high-level" a programming language is. In the 1960s, a high-level programming language using a compiler was commonly called an ''autocode''. Examples of autocodes are COBOL and Fortran. The first high-level programming language designed for computers was Plankalkül, created by Konrad Zuse. However, it was not implemented in his time, and his original contributions were largely isolated from other developments due to World War II, aside from th ...

Structured Programming Languages
Structuring, also known as smurfing in banking jargon, is the practice of executing financial transactions such as making bank deposits in a specific pattern, calculated to avoid triggering financial institutions to file reports required by law, such as the United States' Bank Secrecy Act (BSA) and Internal Revenue Code section 6050I (relating to the requirement to file Form 8300). Structuring may be done in the context of money laundering, fraud, and other financial crimes. Legal restrictions on structuring are concerned with limiting the size of domestic transactions for individuals. Definition Structuring is the act of parceling what would otherwise be a large financial transaction into a series of smaller transactions to avoid scrutiny by regulators and law enforcement. Typically each of the smaller transactions is executed in an amount below some statutory limit that normally does not require a financial institution to file a report with a government agency.

Procedural Programming Languages
Procedural programming is a programming paradigm, derived from imperative programming, based on the concept of the ''procedure call''. Procedures (a type of routine or subroutine) simply contain a series of computational steps to be carried out. Any given procedure might be called at any point during a program's execution, including by other procedures or itself. The first major procedural programming languages appeared circa 1957–1964, including Fortran, ALGOL, COBOL, PL/I and BASIC. Pascal and C were published circa 1970–1972. Computer processors provide hardware support for procedural programming through a stack register and instructions for calling procedures and returning from them. Hardware support for other types of programming is possible, but no attempt was commercially successful (for example Lisp machines or Java processors). Procedures and modularity Modularity is generally desirable, especially in large, complicated programs. Inputs are usually ...

List (abstract Data Type)
In computer science, a list or sequence is an abstract data type that represents a finite number of ordered values, where the same value may occur more than once. An instance of a list is a computer representation of the mathematical concept of a tuple or finite sequence; the (potentially) infinite analog of a list is a stream. Lists are a basic example of containers, as they contain other values. If the same value occurs multiple times, each occurrence is considered a distinct item. The name list is also used for several concrete data structures that can be used to implement abstract lists, especially linked lists and arrays. In some contexts, such as in Lisp programming, the term list may refer specifically to a linked list rather than an array. In class-based programming, lists are usually provided as instances of subclasses of a generic "list" class, and traversed via separate iterators. Many programming languages provide support for list data types, and have special s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuple
In mathematics, a tuple is a finite ordered list (sequence) of elements. An -tuple is a sequence (or ordered list) of elements, where is a non-negative integer. There is only one 0-tuple, referred to as ''the empty tuple''. An -tuple is defined inductively using the construction of an ordered pair. Mathematicians usually write tuples by listing the elements within parentheses "" and separated by a comma and a space; for example, denotes a 5-tuple. Sometimes other symbols are used to surround the elements, such as square brackets "nbsp; or angle brackets "⟨ ⟩". Braces "" are used to specify arrays in some programming languages but not in mathematical expressions, as they are the standard notation for sets. The term ''tuple'' can often occur when discussing other mathematical objects, such as vectors. In computer science, tuples come in many forms. Most typed functional programming languages implement tuples directly as product types, tightly associated with algebr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Development Environment
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not. The boundary between an IDE and other parts of the broader software development environment is not well-defined; sometimes a version control system or various tools to simplify the construction of a graphical user interface (GUI) are integrated. Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram for use in object-oriented software development. Overview Integrated development environments are designed to maximize programmer productivity by providing tight-knit components with similar user interfaces. IDEs present a single program i ...

Computer Programming
Computer programming is the process of performing a particular computation (or more generally, accomplishing a specific computing result), usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms (usually in a chosen programming language, commonly referred to as coding). The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algori ...

Pascal (programming Language)
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversi ...
