29 dez who invented cobol

From 1959 to 1961, Hopper lead the team that invented COBOL (Common Business-Oriented Language), the first user-friendly business computer software pro… Any option may only be selected once. [120], COBOL does not provide a way to hide methods. Another simple example to illustrate this (slightly simplified from Veerman & Verhoeven 2006): One might expect that the output is "1 2 3 END END END", and in fact that is what some COBOL compilers will produce. COBOL, the programming language, was not discovered it was invented and developed by Grace Hopper, William Selden, Gertrude Tierney, Howard Bromberg, Howard Discount, Vernon Reeves Jean E Sammet. They described new versions in 1968, 1969, 1970 and 1973, including changes such as new inter-program communication, debugging and file merging facilities as well as improved string-handling and library inclusion features. Isolation from the computer science community, *> Terminator period ("implicit termination"), *> Scope terminators ("explicit termination"). A sub-committee was formed to analyze existing languages and was made up of six individuals:[21][63], The sub-committee did most of the work creating the specification, leaving the short-range committee to review and modify their work before producing the finished specification. This is done with the PERFORM sub-1 THRU sub-n construct: The output of this program will be: "A A B C". Similar to alphanumeric, but using an extended character set, e.g. [23][24] Their official mission, however, was to identify the strengths and weaknesses of existing programming languages and did not explicitly direct them to create a new language. This was a blow to the short-range committee, who had made good progress on the specification. COBOL (/ˈkoʊbɒl, -bɔːl/; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. One, invented by Bob Bemer, was the IBM COMTRAN language. By 1957, Dr. Hopper's quest for a higher level programming language led to the development of Flow-Matic, the predecessor to COBOL (Common . Continuation lines are not present, and the >>PAGE directive replaces the / indicator.[118]. The final approved ISO standard was approved and published in late 2002.[95]. ANSI produced USA Standard COBOL X3.23 in August 1968, which became the cornerstone for later versions. [...] Its very name is seldom uttered without ritual expressions of disgust or horror. [14] Representatives included Grace Hopper (inventor of the English-like data processing language FLOW-MATIC), Jean Sammet and Saul Gorn. [178] Donald Nelson, chair of the CODASYL COBOL committee, said in 1984 that "academics ... hate COBOL" and that computer science graduates "had 'hate COBOL' drilled into them". In the above example, elementary item num and group item the-date are subordinate to the record some-record, while elementary items the-year, the-month, and the-day are part of the group item the-date. 'Price Is Right' fans freak out after family wins 3 cars A majority agreed that the language should make maximal use of English, be capable of change, be machine-independent and be easy to use, even at the expense of power. By the end of 1956, Hopper had UNIVAC I & II understanding twenty English-like statements using FLOW-MATIC. } [133], The USAGE clause declares the format data is stored in. It was observed that increasing memory would drastically increase speed and that compilation costs varied wildly: costs per statement were between $0.23 and $18.91. EVALUATE is a switch-like statement with the added capability of evaluating multiple values and conditions. The GOBACK statement is a return statement and the STOP statement stops the program. [38], The usefulness of the committee's work was subject of great debate. COBOL-85 then added nested subprograms, allowing programmers to hide subprograms. [21], Representatives enthusiastically described a language that could work in a wide variety of environments, from banking and insurance to utilities and inventory control. [123], A common non-standard extension is the line sequential organization, used to process text files. By the time her mother figured out what she had been up to,… Sure, it does. In fixed-format, code must be aligned to fit in certain areas (a hold-over from using punched cards). [29], The committee mainly examined the FLOW-MATIC, AIMACO and COMTRAN programming languages. [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). A frustrated Howard Bromberg bought a $15 tombstone with "COBOL" engraved on it and sent it to Charles Phillips to demonstrate his displeasure. In 1959 Grace Hopper invented the computer language, COBOL. On 6 and 7 December, the same COBOL program (albeit with minor changes) ran on an RCA computer and a Remington-Rand Univac computer, demonstrating that compatibility could be achieved.[68]. [151] In keeping with COBOL programming of that era, HELLO, WORLD is displayed in all capital letters. For example, a condition can be expressed as  x IS GREATER THAN y or more concisely as  x GREATER y  or  x > y. The data division is split into six sections which declare different items: the file section, for file records; the working-storage section, for static variables; the local-storage section, for automatic variables; the linkage section, for parameters and the return value; the report section and the screen section, for text-based user interfaces. SIZE COBOL was quickly adopted there, in other federal agencies, and in private industry. [188], Programming language with English-like syntax. COBOL (common business oriented language) is a prominent computer language designed specifically for commercial uses, created in 1960 by a team drawn from several computer makers and the Pentagon. It was created as part of a US Department of Defense effort to create a portable programming language for data processing. 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. [109], By 2019, the number of COBOL programmers was shrinking fast due to retirements, leading to an impending skills gap in business and government organizations which still use mainframe systems for high-volume transaction processing. Exceptions are raised by a RAISE statement and caught with a handler, or declarative, defined in the DECLARATIVES portion of the procedure division. The relative influences of which languages were used continues to this day in the recommended advisory printed in all COBOL reference manuals: COBOL is an industry language and is not the property of any company or group of companies, or of any organization or group of organizations. Amazing Grace or Who Invented Cobol. Is COBOL the most evil language ever invented? Such features included boolean expressions, formulas and table subscripts (indices). The report writer was slated to be removed from COBOL, but was reinstated before the standard was published. _ Originally used for card/line numbers (facilitating mechanical punched card sorting to assure intended program code sequence after manual editing/handling), this area is ignored by the compiler. We shortened it and got rid of a lot of unnecessary notation. _ Each record must have a unique key, but other, alternate, record keys need not be unique. Of her many claims to fame, she invented the first compiler and helped spread the adoption of machine-independent programming languages. [100], Between 2003 and 2009, three technical reports were produced describing object finalization, XML processing and collection classes for COBOL. Floating-point, in either an implementation-dependent format or according to IEEE 754. This situation improved as COBOL adopted more features. [101], COBOL 2014 includes the following changes:[102], COBOL programs are used globally in governments and businesses and are running on diverse operating systems such as z/OS, z/VSE, VME, Unix, OpenVMS and Windows. Additional common languages, such as ALGOL and standard forms of FORTRAN, were developed for scientists and engineers.Written initially for the short range, COBOL proved so useful that it dominated much of government and business data processing for decades. literal-1 ON [71], In late 1962, IBM announced that COBOL would be their primary development language and that development of COMTRAN would cease. An item with a higher level-number is subordinate to an item with a lower one. [19], On 28 and 29 May 1959 (exactly one year after the Zürich ALGOL 58 meeting), a meeting was held at the Pentagon to discuss the creation of a common programming language for business. [18], Charles Phillips agreed to sponsor the meeting and tasked the delegation with drafting the agenda. In sequential files, records are contiguous and must be traversed sequentially, similarly to a linked list. In 2012, Computerworld surveys found out that over 60% of organizations still using COBOL. 1965 1959: COBOL started being developed in 1959 by Grace Hopper and Bob Bemer. Any option may only be selected once. [82] It was one of the first high-level programming languages created. some people can toss out a single name if they want, but they will be mistaken .
