Otherwise, an output line will be printed showing the input values for A, B, and C, followed by the computed AREA of the triangle as a floating-point number occupying ten spaces along the line of output and showing 2 digits after
2208-486: A neutral zone to safeguard its status as a free port. The colonial government prepared for a possible attack, evacuating all British women and children in 1940. The Imperial Japanese Army attacked Hong Kong on 8 December 1941 , the same morning as its attack on Pearl Harbor . Hong Kong was occupied by Japan for almost four years before the British resumed control on 30 August 1945. Its population rebounded quickly after
2346-413: A number of significant features to address many of the shortcomings of FORTRAN 66: In this revision of the standard, a number of features were removed or altered in a manner that might invalidate formerly standard-conforming programs. (Removal was the only allowable alternative to X3J3 at that time, since the concept of " deprecation " was not yet available for ANSI standards.) While most of the 24 items in
2484-411: A problem. IBM's FORTRAN II appeared in 1958. The main enhancement was to support procedural programming by allowing user-written subroutines and functions which returned values with parameters passed by reference . The COMMON statement provided a way for subroutines to access common (or global ) variables. Six new statements were introduced: Over the next few years, FORTRAN II added support for
2622-439: A program deck and add sequence numbers. Some early compilers, e.g., the IBM 650's, had additional restrictions due to limitations on their card readers. Keypunches could be programmed to tab to column 7 and skip out after column 72. Later compilers relaxed most fixed-format restrictions, and the requirement was eliminated in the Fortran 90 standard. Within the statement field, whitespace characters (blanks) were ignored outside

Although median household income steadily increased during the decade to 2021, the wage gap remained high; the 90th percentile of earners receive 41% of all income. The city has the most billionaires per capita, with one billionaire per 109,657 people, as well as
3174-409: A simple means for FORTRAN 77 programmers to issue POSIX system calls. Over 100 calls were defined in the document – allowing access to POSIX-compatible process control, signal handling, file system control, device control, procedure pointing, and stream I/O in a portable manner. The much-delayed successor to FORTRAN 77, informally known as Fortran 90 (and prior to that, Fortran 8X ),
3312-456: A simplified, interpreted version of FORTRAN I (with only 12 statements not 32) for "load and go" operation was available (at least for the early IBM 1620 computer). Modern Fortran, and almost all later versions, are fully compiled, as done for other high-performance languages. The development of Fortran paralleled the early evolution of compiler technology , and many advances in the theory and design of compilers were specifically motivated by

Hong Kong is the world's third-ranked global financial centre (behind New York City and London ), ninth-largest exporter, and eighth-largest importer. Its currency, the Hong Kong dollar , is the ninth most traded currency in the world. Home to
3588-487: A stack is maintained by software and the return address is stored on the stack before the call is made and restored after the call returns. Although not specified in FORTRAN 77, many F77 compilers supported recursion as an option, and the Burroughs mainframes , designed with recursion built-in, did so by default. It became a standard in Fortran 90 via the new keyword RECURSIVE. This program, for Heron's formula , reads data on
3726-432: A tape reel containing three 5-digit integers A, B, and C as input. There are no "type" declarations available: variables whose name starts with I, J, K, L, M, or N are "fixed-point" (i.e. integers), otherwise floating-point. Since integers are to be processed in this example, the names of the variables start with the letter "I". The name of a variable must start with a letter and can continue with both letters and digits, up to
3864-414: A text literal. This allowed omitting spaces between tokens for brevity or including spaces within identifiers for clarity. For example, AVG OF X was a valid identifier, equivalent to AVGOFX , and 101010 DO101I = 1 , 101 was a valid statement, equivalent to 10101 DO 101 I = 1 , 101 because the zero in column 6 is treated as if it were a space (!), while 101010 DO101I = 1.101
4002-403: A waterfall on the island flowed. The simplified name Hong Kong was frequently used by 1810. The name was also commonly written as the single word Hongkong until 1926, when the government officially adopted the two-word name. Some corporations founded during the early colonial era still keep this name, including Hongkong Land , Hongkong Electric Company , Hongkong and Shanghai Hotels and

This table is obtained by running the program once in Monte-Carlo fashion, in which the outcome of conditional transfers arising out of IF-type statements and computed GO TO's
5244-487: The DOUBLE PRECISION and COMPLEX data types. Early FORTRAN compilers supported no recursion in subroutines. Early computer architectures supported no concept of a stack, and when they did directly support subroutine calls, the return location was often stored in one fixed location adjacent to the subroutine code (e.g. the IBM 1130 ) or a specific machine register ( IBM 360 et seq ), which only allows recursion if
5382-537: The Basic Law of Hong Kong for 50 years after the handover. It does not specify how Hong Kong will be governed after 2047, and the central government's role in determining the territory's future system of government is the subject of political debate and speculation. Hong Kong's political and judicial systems may be integrated with China's at that time, or the territory may continue to be administered separately. However, in response to large-scale protests in 2019 and 2020 ,
5520-578: The Basic Law of Hong Kong is the regional constitution. The regional government is composed of three branches: The chief executive is the head of government and serves for a maximum of two five-year terms. The State Council (led by the Premier of China ) appoints the chief executive after nomination by the Election Committee , which is composed of 1500 business, community, and government leaders. The Legislative Council has 90 members, each serving
5658-592: The Chinese People's Political Consultative Conference appointed by the central government. Chinese national law does not generally apply in the region, and Hong Kong is treated as a separate jurisdiction. Its judicial system is based on common law , continuing the legal tradition established during British rule. Local courts may refer to precedents set in English law and overseas jurisprudence. However, mainland criminal procedure law applies to cases investigated by

Although the Chairman of the Central Military Commission is supreme commander of the armed forces, the regional government may request assistance from the garrison. Hong Kong residents are not required to perform military service, and current law has no provision for local enlistment, so its defence is composed entirely of non-Hongkongers. The central government and Ministry of Foreign Affairs handle diplomatic matters, but Hong Kong retains

10488-620: The agreement. After more than a year of further hostilities, Hong Kong Island was formally ceded to the United Kingdom in the 1842 Treaty of Nanking . Administrative infrastructure was quickly built by early 1842, but piracy, disease, and hostile Qing policies initially prevented the government from attracting commerce. Conditions on the island improved during the Taiping Rebellion in the 1850s, when many Chinese refugees, including wealthy merchants, fled mainland turbulence and settled in
10626-399: The area of the New Territories has nine districts. Each district is represented by a district council . The district councils advise the government on local issues such as public facility provisioning, community programme maintenance, cultural promotion, and environmental policy. As of 2024, there are a total of 470 district council seats, 88 of which are directly elected. In May 2023,
10764-1152: The chief executive is selected by establishment politicians and corporate members of the Election Committee rather than directly elected. Despite universal suffrage being established as ultimate goals for the election of the chief executive and all members of the Legislative Council in Articles 45 and 68 of the basic law, the legislature is only partially directly elected, and the executive continues to be nominated by an unrepresentative body. The government has been repeatedly petitioned to introduce direct elections for these positions, but has not introduced these direct elections as of 2024. Ethnic minorities (except those of European ancestry) have marginal representation in government and often experience discrimination in housing, education, and employment. Employment vacancies and public service appointments frequently have language requirements which minority job seekers do not meet, and language education resources remain inadequate for Chinese learners. Foreign domestic helpers , mostly women from
10902-621: The colony. Further tensions between the British and Qing over the opium trade escalated into the Second Opium War . The Qing were again defeated and forced to give up Kowloon Peninsula and Stonecutters Island in the Convention of Peking . By the end of this war, Hong Kong had evolved from a transient colonial outpost into a major entrepôt . Rapid economic improvement during the 1850s attracted foreign investment, as potential stakeholders became more confident in Hong Kong's future. The colony
11040-484: The conflict list (see Appendix A2 of X3.9-1978) addressed loopholes or pathological cases permitted by the prior standard but rarely used, a small number of specific capabilities were deliberately removed, such as: A Fortran 77 version of the Heron program requires no modifications to the Fortran 66 version. However this example demonstrates additional cleanup of the I/O statements, including using list-directed I/O, and replacing
11178-575: The council, while none of the pro-Beijing lawmakers were detained. Annual commemorations of the 1989 Tiananmen Square protests and massacre were also cancelled amidst fears of violating the national security law. In March 2021, the Chinese central government unilaterally changed Hong Kong's electoral system and established the Candidate Eligibility Review Committee , which would be tasked with screening and evaluating political candidates for their "patriotism", effectively crushing
11316-551: The decimal point, the .2 in F10.2 of the FORMAT statement with label 601. IBM also developed a FORTRAN III in 1958 that allowed for inline assembly code among other features; however, this version was never released as a product. Like the 704 FORTRAN and FORTRAN II, FORTRAN III included machine-dependent features that made code written in it unportable from machine to machine. Early versions of FORTRAN provided by other vendors suffered from
11454-559: The early history of FORTRAN was the decision by the American Standards Association (now American National Standards Institute (ANSI)) to form a committee sponsored by the Business Equipment Manufacturers Association (BEMA) to develop an American Standard Fortran . The resulting two standards, approved in March 1966, defined two languages, FORTRAN (based on FORTRAN IV, which had served as
11592-404: The end of the New Territories lease approached, and Governor Murray MacLehose raised the question of Hong Kong's status with Deng Xiaoping in 1979. Diplomatic negotiations with China resulted in the 1984 Sino-British Joint Declaration , in which the United Kingdom agreed to the handover of the colony in 1997 and China would guarantee Hong Kong's economic and political systems for 50 years after
11730-432: The entire card to be treated as a comment and ignored by the compiler. Otherwise, the columns of the card were divided into four fields: Columns 73 to 80 could therefore be used for identification information, such as punching a sequence number or text, which could be used to re-order cards if a stack of cards was dropped; though in practice this was reserved for stable, production programs. An IBM 519 could be used to copy
11868-541: The first Power of Partnership Award in June 2006 by START-IT magazine. Also in 2006, GXS acquired product data quality service provider, UDEX. On June 4, 2007, Verizon announced that it will sell GXS Trading Grid services as Custom Supply Chain Managed Services and Invoice Automation Service. In 2008, Accenture and GXS entered into a global partnership to support Accenture Supply Chain Services (ASCS) business. Through
12006-501: The generated code, the results of which were used to optimize the placement of basic blocks in memory—a very sophisticated optimization for its time. The Monte Carlo technique is documented in Backus et al.'s paper on this original implementation, The FORTRAN Automatic Coding System : The fundamental unit of program is the basic block ; a basic block is a stretch of program which has one entry point and one exit point. The purpose of section 4
12144-547: The government proposed reforms to the District Council electoral system which further cut the number of directly elected seats from 452 to 88, and total seats from 479 to 470. A requirement that district council candidates be vetted and approved by the District Council Eligibility Review Committee was also proposed. The Legislative Council approved the reforms in July 2023. Hong Kong
12282-418: The handover. The impending handover triggered a wave of mass emigration as residents feared an erosion of civil rights, the rule of law, and quality of life. Over half a million people left the territory during the peak migration period, from 1987 to 1996. The Legislative Council became a fully elected legislature for the first time in 1995 and extensively expanded its functions and organisations throughout
12420-472: The harbour's freshwater influx from the Pearl River or to the odour from incense factories lining the coast of northern Kowloon . The incense was stored near Aberdeen Harbour for export before Victoria Harbour was developed. Sir John Davis (the second colonial governor) offered an alternative origin; Davis said that the name derived from "Hoong-keang" ("red torrent"), reflecting the colour of soil over which
12558-521: The historically most important dialect. An important practical extension to FORTRAN 77 was the release of MIL-STD-1753 in 1978. This specification, developed by the U.S. Department of Defense , standardized a number of features implemented by most FORTRAN 77 compilers but not included in the ANSI FORTRAN 77 standard. These features would eventually be incorporated into the Fortran 90 standard. The IEEE 1003.9 POSIX Standard, released in 1991, provided
12696-451: The increasing popularity of FORTRAN spurred competing computer manufacturers to provide FORTRAN compilers for their machines, so that by 1963 over 40 FORTRAN compilers existed. FORTRAN was provided for the IBM 1401 computer by an innovative 63-phase compiler that ran entirely in its core memory of only 8000 (six-bit) characters. The compiler could be run from tape, or from a 2200-card deck; it used no further tape or disk storage. It kept
12834-526: The language as "Fortran" with initial caps since Fortran 90. In late 1953, John W. Backus submitted a proposal to his superiors at IBM to develop a more practical alternative to assembly language for programming their IBM 704 mainframe computer . Backus' historic FORTRAN team consisted of programmers Richard Goldberg, Sheldon F. Best, Harlan Herrick, Peter Sheridan, Roy Nutt , Robert Nelson, Irving Ziller, Harold Stern, Lois Haibt , and David Sayre . Its concepts included easier entry of equations into
12972-401: The last years of the colonial rule. The handover of Hong Kong to China was at midnight on 1 July 1997, after 156 years of British rule. Immediately after the handover, Hong Kong was severely affected by several crises. The Hong Kong government was forced to use substantial foreign exchange reserves to maintain the Hong Kong dollar's currency peg during the 1997 Asian financial crisis , and
13110-528: The maritime area is included) consists of Hong Kong Island , the Kowloon Peninsula , the New Territories , Lantau Island , and over 200 other islands. Of the total area, 1,073 km (414 sq mi) is land and 35 km (14 sq mi) is water. The territory's highest point is Tai Mo Shan , 957 metres (3,140 ft) above sea level. Urban development is concentrated on the Kowloon Peninsula, Hong Kong Island, and in new towns throughout
13248-656: The minimum amount of memory the compiler needed to run. The letters (F, G, H) matched the codes used with System/360 model numbers to indicate memory size, each letter increment being a factor of two larger: Digital Equipment Corporation maintained DECSYSTEM-10 Fortran IV (F40) for PDP-10 from 1967 to 1975. Compilers were also available for the UNIVAC 1100 series and the Control Data 6000 series and 7000 series systems. At about this time FORTRAN IV had started to become an important educational tool and implementations such as
13386-599: The name OpenText GXS. In 2003, GXS acquired Celarix, a supply-chain optimization software and services vendor, and in 2004 GXS acquired HAHT Commerce. In 2005, GXS acquired the EDI and Business Exchange Services assets of IBM Corporation. In May 2006, Microsoft and GXS formed a partnership to integrate Microsoft technologies with the GXS Trading Grid. Microsoft endorsed the GXS Trading Grid as its recommended network for Microsoft BizTalk Server . GXS and Microsoft were awarded
13524-436: The need for a separate legal entity for shared-ownership, eventually GEISCO quietly became just General Electric Information Services (GEIS). As GEIS, the service was expanded with Fortran 77 and C programming languages (1985), but was hard hit by the availability of Personal Computers supplanting much of the isolated computational loads previously accomplished on time sharing. GEIS refocused on "Network-Based Services" where
13662-465: The need to generate efficient code for Fortran programs. The initial release of FORTRAN for the IBM 704 contained 32 statements , including: The arithmetic IF statement was reminiscent of (but not readily implementable by) a three-way comparison instruction (CAS—Compare Accumulator with Storage) available on the 704. The statement provided the only way to compare numbers—by testing their difference, with an attendant risk of overflow. This deficiency
13800-726: The north and occasionally result in chilly weather. Autumn is the sunniest season, whilst spring is generally cloudy. Snowfall has been extremely rare in Hong Kong; the last reported instance was on Tai Mo Shan in 1975. Hong Kong averages 1,709 hours of sunshine per year. Historic temperature extremes at the Hong Kong Observatory are 36.6 °C (97.9 °F) on 22 August 2017 and 0.0 °C (32.0 °F) on 18 January 1893. The highest and lowest recorded temperatures in all of Hong Kong are 39.0 °C (102 °F) at Wetland Park on 22 August 2017, and −6.0 °C (21.2 °F) at Tai Mo Shan on 24 January 2016 . Hong Kong has
13938-426: The opium trade. The commissioner destroyed opium stockpiles and halted all foreign trade, triggering a British military response and the First Opium War . The Qing surrendered early in the war and ceded Hong Kong Island in the Convention of Chuenpi . British forces began controlling Hong Kong shortly after the signing of the convention, from 26 January 1841. However, both countries were dissatisfied and did not ratify
14076-464: The outset, GEIS services were always priced as a combination of proprietary Computer Resource Units (CRU), Terminal Connect Hours (TCH) and Kilo-Characters (KC). The CRU was a highly proprietary formula which took in variables such as the CPU time, memory size and file system input-output operations performed in a program run. It was carefully adjusted whenever new hardware (or sometimes operating system software)
14214-591: The population speak Mandarin, with 2.3% native speakers and 51.9% as a second language. Traditional Chinese characters are used in writing, rather than the simplified characters used in the mainland . Among the religious population, the traditional " three teachings " of China, Buddhism , Confucianism , and Taoism , have the most adherents (20%), followed by Christianity (12%) and Islam (4%). Followers of other religions, including Sikhism , Hinduism , and Judaism , generally originate from regions where their religion predominates. Life expectancy in Hong Kong
14352-440: The post-war decades to provide safer housing, integrity in the civil service, and more reliable transportation. Nevertheless, widespread public discontent resulted in multiple protests from the 1950s to 1980s, including pro- Republic of China and pro- Chinese Communist Party protests. In the 1967 Hong Kong riots , pro- PRC protestors clashed with the British colonial government. As many as 51 were killed and 802 were injured in
14490-660: The power of the mainframes increased, GE replaced the dedicated DATANET-30 (DN-30) communications computers with a multi-tier network composed of DN-30 and other computers forming a world-wide star network topology with redundant circuits and switchers. With the reimplementation of the time-sharing system on GE 635 computers at Dartmouth and the growing network, GE renamed the system the Mark II time sharing service. The computers were accessed in ASCII text-mode on 300 and 1,200 bps terminals . They offered pre-written business, mathematics and engineering applications in libraries (as well as
14628-420: The problem. Later, an error-handling subroutine to handle user errors such as division by zero, developed by NASA, was incorporated, informing users of which line of code contained the error. Before the development of disk files, text editors and terminals, programs were most often entered on a keypunch keyboard onto 80-column punched cards , one line to a card. The resulting deck of cards would be fed into
14766-519: The program in memory and loaded overlays that gradually transformed it, in place, into executable form, as described by Haines. This article was reprinted, edited, in both editions of Anatomy of a Compiler and in the IBM manual "Fortran Specifications and Operating Procedures, IBM 1401". The executable form was not entirely machine language ; rather, floating-point arithmetic, sub-scripting, input/output, and function references were interpreted, preceding UCSD Pascal P-code by two decades. GOTRAN ,
14904-473: The recovery from this was muted by an H5N1 avian-flu outbreak and a housing surplus. This was followed by the 2003 SARS epidemic , during which the territory experienced its most serious economic downturn. Chinese communists portrayed the return of Hong Kong as key moment in the PRC's rise to great power status. Political debates after the handover have centred around the region's democratic development and
15042-531: The region into a wasteland. The Kangxi Emperor lifted the maritime trade prohibition, allowing foreigners to enter Chinese ports in 1684. Qing authorities established the Canton System in 1757 to regulate trade more strictly, restricting non-Russian ships to the port of Canton . Although European demand for Chinese commodities like tea, silk, and porcelain was high, Chinese interest in European manufactured goods
15180-601: The release of the FORTRAN 66 standard, compiler vendors introduced several extensions to Standard Fortran , prompting ANSI committee X3J3 in 1969 to begin work on revising the 1966 standard, under sponsorship of CBEMA , the Computer Business Equipment Manufacturers Association (formerly BEMA). Final drafts of this revised standard circulated in 1977, leading to formal approval of the new FORTRAN standard in April 1978. The new standard, called FORTRAN 77 and officially denoted X3.9-1978, added
15318-699: The remainder of the Pro-Democracy camp . Hong Kong is on China's southern coast, 60 km (37 mi) east of Macau, on the east side of the mouth of the Pearl River estuary . It is surrounded by the South China Sea on all sides except the north, which neighbours the Guangdong city of Shenzhen along the Sham Chun River . The territory's 1,110.18 km (428.64 sq mi) area (2,754.97 km if
15456-412: The rest of the country. All travellers between Hong Kong and China and Macau must pass through border controls, regardless of nationality. Mainland Chinese citizens do not have right of abode in Hong Kong and are subject to immigration controls. Public finances are handled separately from the national government; taxes levied in Hong Kong do not fund the central authority. The Hong Kong Garrison of
15594-514: The risk of becoming even more "too successful." With the rise of the Internet, GEIS' failure to provide email service until 1993, the extremely slow speed of the character-based Mark III network, the lack of an internet portal, and competition from ISPs , CompuServe, and AOL; GEnie ended on the last day of the millennium. Mark III service and GEIS itself soon followed. In 2000, GEIS was rebranded GXS ( G lobal E x change S ervices). In June 2002, GXS
15732-428: The same disadvantage. IBM began development of FORTRAN IV in 1961 as a result of customer demands. FORTRAN IV removed the machine-dependent features of FORTRAN II (such as READ INPUT TAPE ), while adding new features such as a LOGICAL data type , logical Boolean expressions , and the logical IF statement as an alternative to the arithmetic IF statement. FORTRAN IV was eventually released in 1962, first for
15870-602: The same files and if a mainframe should crash, users could login again instantly to another computer in the cluster. This created availability numbers often above 99.99%. As the GE network grew, the Mark III mainframes were eventually located in three processing centers called Supercenters. The center in Brook Park, Ohio, was supplemented by first one in Rockville, Maryland (1974) and in (1977) Amstelveen, The Netherlands. All were completely networked and equally accessible from anywhere in
16008-465: The southern coast of Hong Kong Island. Aberdeen was an initial point of contact between British sailors and local fishermen. Although the source of the romanised name is unknown, it is generally believed to be an early phonetic rendering of the Cantonese (or Tanka Cantonese ) phrase hēung góng . The name translates as "fragrant harbour" or "incense harbour". "Fragrant" may refer to the sweet taste of
16146-481: The southwest. The humid nature of Hong Kong exacerbates the warmth of summer. Typhoons occur most often then, sometimes resulting in floods or landslides. Also rarely occurring are waterspouts and tornadoes , which occurred at Hong Kong International Airport on 26 September 2020 and at Victoria Harbour on 28 September 2024. Winters are short, mild and usually sunny at the beginning, becoming cloudy towards February. Frequent cold fronts bring strong, cooling winds from
16284-460: The territory. The vast majority also hold Chinese nationality , automatically granted to all ethnic Chinese residents at the handover. Headline population density exceeds 7,060 people/km , and is the fourth-highest in the world. The predominant language is Cantonese , a variety of Chinese originating in Guangdong. It is spoken by 93.7% of the population, 88.2% as a first language and 5.5% as
16422-503: The territory. Older government buildings are examples of colonial architecture. The 1846 Flagstaff House , the former residence of the Commander of the British forces in Hong Kong , is the oldest Western-style building in Hong Kong. Some buildings, such as the Court of Final Appeal Building and the Hong Kong Observatory retain their original functions, and others have been adapted and reused ;
16560-514: The traders were expelled after military clashes in the 1520s, Portuguese-Chinese trade relations were re-established by 1549 . Portugal acquired a permanent lease for Macau in 1887. After the Qing conquest , maritime trade was banned under the Haijin policies. From 1661 to 1683, the population of most of the area forming present day Hong Kong was cleared under the Great Clearance , turning
16698-475: The violence, including dozens killed by the Royal Hong Kong Police via beatings and shootings. Although the territory's competitiveness in manufacturing gradually declined because of rising labour and property costs, it transitioned to a service-based economy. By the early 1990s, Hong Kong had established itself as a global financial centre and shipping hub. The colony faced an uncertain future as
16836-730: The war, as skilled Chinese migrants fled from the Chinese Civil War and more refugees crossed the border when the Chinese Communist Party took control of mainland China in 1949. Hong Kong became the first of the Four Asian Tiger economies to industrialise during the 1950s. With a rapidly increasing population, the colonial government attempted reforms to improve infrastructure and public services. The public-housing estate programme , Independent Commission Against Corruption , and Mass Transit Railway were all established during
16974-494: The world's largest number of skyscrapers , with 554 towers taller than 150 metres (490 ft), and the third-largest number of high-rise buildings in the world. The lack of available space restricted development to high-density residential tenements and commercial complexes packed closely together on buildable land. Single-family detached homes are uncommon and generally only found in outlying areas. The International Commerce Centre and Two International Finance Centre are
17112-402: The world, allowing GE to move load from one center to another and transmit off-site backups for disaster recovery purposes. In 1979 the distribution agreement with Honeywell led to the formation of a joint-venture company called GE Information Services Company, or GEISCO. Three years later, GEISCO became a wholly owned GE subsidiary with the buy-out of Honeywell's interest in the venture. Without
17250-453: The world-wide availability of homogenous access to a customer's applications and data could be leveraged to advantage. Services like sales-force reporting, international banking and transfers, customer support and eventually e-mail (delayed by GE's aversion to running afoul of international common-carrier laws) all required a highly reliable worldwide network and GEIS had the biggest and the best. GEIS also tried to adapt its pricing model. Since
17388-420: Was 81.3 years for males and 87.2 years for females in 2022, one of the highest in the world. Cancer , pneumonia , heart disease , cerebrovascular disease , and accidents are the territory's five leading causes of death. The universal public healthcare system is funded by general-tax revenue, and treatment is highly subsidised; on average, 95% of healthcare costs are covered by the government. The city has
17526-498: Was acquired by venture capital firm Francisco Partners from General Electric (GE). It then operated as an independent firm, although GE retains a minority share in its investments. In 2011, GXS Trading Grid was named "SaaS Product of the Year" by Techworld. On November 5, 2013, OpenText announced its intention to acquire GXS . In January 2014, GXS was acquired by Canadian-based OpenText Corporation (NASDAQ: OTEX) (TSX: OTC) and adopted
17664-480: Was also standard-conforming under Fortran 90, and either standard should have been usable to define its behavior. A small set of features were identified as "obsolescent" and were expected to be removed in a future standard. All of the functionalities of these early-version features can be performed by newer Fortran features. Some are kept to simplify porting of old programs but many were deleted in Fortran 95. Fortran 95 , published officially as ISO/IEC 1539-1:1997,
17802-489: Was always saddled with its initial business justification: a means to generate extra revenue from unused computer and network capacity outside the mainstream business use load times. This made the service appear largely costless from a computer and network resource accounting view and was the basis of the ongoing refusal by management to lease additional mainframes to support the service when it became popular. This choked developments GEnie could have made, but didn't dare deploy at
17940-414: Was deployed so that test programs generated the same CRU numbers over many years, giving customers stability. TCH and KC meaning are, as expected, the time connected to the network and the number of characters sent in or out. The monetary pricing attached to these numbers could vary over time and from country to country. Responding to competition and customer values, GEIS introduced "transaction pricing" where
18078-430: Was divided into four fields, as described above. Two compilers of the time, IBM "G" and UNIVAC, allowed comments to be written on the same line as instructions, separated by a special character: "master space": V (perforations 7 and 8) for UNIVAC and perforations 12/11/0/7/8/9 (hexadecimal FF) for IBM. These comments were not to be inserted in the middle of continuation cards. Perhaps the most significant development in
18216-410: Was finally released as ISO/IEC standard 1539:1991 in 1991 and an ANSI Standard in 1992. In addition to changing the official spelling from FORTRAN to Fortran, this major revision added many new features to reflect the significant changes in programming practice that had evolved since the 1978 standard: Unlike the prior revision, Fortran 90 removed no features. Any standard-conforming FORTRAN 77 program
18354-528: Was further expanded in 1898 when the United Kingdom obtained a 99-year lease of the New Territories. The University of Hong Kong was established in 1911 as the territory's first institution of higher education. Kai Tak Airport began operation in 1924, and the colony avoided a prolonged economic downturn after the 1925–26 Canton–Hong Kong strike . At the start of the Second Sino-Japanese War in 1937, Governor Geoffry Northcote declared Hong Kong
18492-519: Was insignificant, so that Chinese goods could only be bought with precious metals. To reduce the trade imbalance, the British sold large amounts of Indian opium to China. Faced with a drug crisis, Qing officials pursued ever more aggressive actions to halt the opium trade. In 1839, the Daoguang Emperor rejected proposals to legalise and tax opium and ordered imperial commissioner Lin Zexu to eradicate
18630-412: Was instead 10101 DO101I = 1.101 , the assignment of 1.101 to a variable called DO101I . Note the slight visual difference between a comma and a period. Hollerith strings , originally allowed only in FORMAT and DATA statements, were prefixed by a character count and the letter H (e.g., 26HTHIS IS ALPHANUMERIC DATA. ), allowing blanks to be retained within the character string. Miscounts were
18768-464: Was later overcome by "logical" facilities introduced in FORTRAN IV. The FREQUENCY statement was used originally (and optionally) to give branch probabilities for the three branch cases of the arithmetic IF statement. It could also be used to suggest how many iterations a DO loop might run. The first FORTRAN compiler used this weighting to perform at compile time a Monte Carlo simulation of
18906-504: Was to run the mainframes in single-processor "clusters", enabled by a specialized and custom hardware box (the "Scratch Pad" (SPAD)) that connected the systems. This allowed up to six fully separate mainframes to coordinate their access to the Mark II file systems. All file system updates were first coordinated on the SPAD before any mainframe wrote updates to the disk file system. This allowed users to be distributed across multiple mainframes, access
19044-454: Was widely adopted by scientists for writing numerically intensive programs, which encouraged compiler writers to produce compilers that could generate faster and more efficient code. The inclusion of a complex number data type in the language made Fortran especially suited to technical applications such as electrical engineering. By 1960, versions of FORTRAN were available for the IBM 709 , 650 , 1620 , and 7090 computers. Significantly,
