who invented cobol

[121] Method overloading was added in COBOL 2014.[122]. Hopper also originated the idea that computer programs could be written in English. [88], Jean Sammet, a short-range committee member, noted that "little attempt was made to cater to the professional programmer, in fact people whose main interest is programming tend to be very unhappy with COBOL" which she attributed to COBOL's verbose syntax. • COBOL was developed in 1959 by the Conference on Data Systems Languages (CODASYL). Hopper's naval duties ended a year after the war, and she became a senior programmer with Remington Rand, where she worked on the first large-scale commercial computer UNIVAC. So, that’s one of the things going on around COBOL. COBOL, one of the oldest programming languages, has withstood the test of time. The following characters are allowed here: Historically up to column 80 for punched cards, it is used to identify the program or sequence the card belongs to, Data stored in the form of 0s and 1s, as a binary number. [29], The committee mainly examined the FLOW-MATIC, AIMACO and COMTRAN programming languages. [175][176][66], Later, COBOL suffered from a shortage of material covering it; it took until 1963 for introductory books to appear (with Richard D. Irwin publishing a college textbook on COBOL in 1966). [164], COBOL syntax has often been criticized for its verbosity. [47][48] Another point of controversy was whether to make keywords context-sensitive and the effect that would have on readability. [22], The meeting resulted in the creation of a steering committee and short, intermediate and long-range committees. A frustrated Howard Bromberg bought a $15 tombstone with "COBOL" engraved on it and sent it to Charles Phillips to demonstrate his displeasure. [147], The original (1959) COBOL specification supported the infamous  ALTER X TO PROCEED TO Y  statement, for which many compilers generated self-modifying code. The subcommittee was given until December to improve it. The delegation impressed Charles A. Phillips, director of the Data System Research Staff at the DoD,[17] who thought that they "thoroughly understood" the DoD's problems. Here's a look at why the programming language remains popular even today. One, invented by Bob Bemer, was the IBM COMTRAN language. [75], Two amendments followed in 1989 and 1993, the first introducing intrinsic functions and the other providing corrections. [46] In the same year, a National Bureau of Standards study concluded that the proposed standard would present few problems. Until COBOL 2002, these were: In COBOL 2002, Areas A and B were merged to form the program-text area, which now ends at an implementor-defined column. Dr Grace Murray Hopper, a rear admiral in the U.S. navy, was also a computer scientist who invented COBOL, "the first user-friendly business computer software program". The written description of COBOL, as well as the specifications for it, were influenced by another language, called FLOW-MATIC. ISO TC97-SC5 installed in 1979 the international COBOL Experts Group, on initiative of Wim Ebbinkhuijsen. In a 1960 test, the same COBOL programs ran successfully on two computers built by different manufacturers. Monopoly used to be invented to point out the evils of capitalism JellyEnt We shortened it and got rid of a lot of unnecessary notation. They are up to 31 characters long and may include letters, digits, hyphens and underscores. [181], There was also significant condescension towards COBOL in the business community from users of other languages, for example FORTRAN or assembler, implying that COBOL could be used only for non-challenging problems. COBOL's syntax is usually described with a unique metalanguage using braces, brackets, bars and underlining. [174] The COBOL specification used a unique "notation", or metalanguage, to define its syntax rather than the new Backus–Naur form which the committee did not know of. After submitting the JCL, the MVS console displayed: Line 10 of the console listing above is highlighted for effect, the highlighting is not part of the actual console output. The fire escape. [9], Testimony before the House of Representatives in 2016 indicated that COBOL is still in use by many federal agencies. [59], 'And what name do you want inscribed?' [38], The usefulness of the committee's work was subject of great debate. Support for generic programming is provided through parameterized classes, which can be instantiated to use any class or interface. The FLOW-MATIC language was particularly influential because it had been implemented and because AIMACO was a derivative of it with only minor changes. literal-1 Hopper was the first to devise the theory of machine-independent programming languages, and the FLOW-MATIC programming language she created using this theory was later extended to create COBOL, an early high-l… [65], During 1960, the list of manufacturers planning to build COBOL compilers grew. Deleted features included the NOTE statement, the EXAMINE statement (which was replaced by INSPECT) and the implementer-defined random access module (which was superseded by the new sequential and relative I/O modules). [177] By 1985, there were twice as many books on Fortran and four times as many on BASIC as on COBOL in the Library of Congress. The fact that something is old may just mean that it has stood the test of time. Fifty years ago, each computer maker used its own programming languages to tell a computer what to do. After the clean-up effort put into these programs for Y2K, a 2003 survey found that many remained in use. It's Grace Hopper, however, who is often called "the mother of the COBOL language." Control breaks occur when a key variable changes it value; for example, when creating a report detailing customers' orders, a control break could occur when the program reaches a different customer's orders. The input-output section contains file-related information. The name COBOL stands for COmmon Business-Oriented Language.COBOL was created because people wanted a language they could use to describe the problems in a way that is independent of the hardware used. The reason is that COBOL, rather than a "return address", operates with what may be called a continuation address. In 1959, government and industry computer experts gathered held a confab on data systems languages and invited Hopper to serve as a technical consultant. Similar to alphanumeric, but using an extended character set, e.g. The vice-president, William Rinehuls, complained that two-thirds of the COBOL community did not know of the committee's existence. [76], Independently of the ANSI committee, the CODASYL Programming Language Committee was working on improving the language. GO TO causes the program to jump to a specified procedure. Grace Hopper, William Selden, Gertrude Tierney, Howard Bromberg, Howard Discount, … COBOL Edition 1965 brought further clarifications to the specifications and introduced facilities for handling mass storage files and tables. [142] Parameters can be passed by reference, by content (where a copy is passed by reference) or by value (but only if a prototype is available). ", in which he was critical of COBOL and several other contemporary languages; remarking that "the use of COBOL cripples the mind". Edsger Dijkstra, a preeminent computer scientist, wrote a letter to the editor of Communications of the ACM, published 1975 entitled "How do we tell truths that might hurt? Literals include numerals (e.g. [37][1], IBM's COMTRAN language, invented by Bob Bemer, was regarded as a competitor to FLOW-MATIC[38][39] by a short-range committee made up of colleagues of Grace Hopper.
