GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from IBM BASICA . Functionally identical to BASICA, its BASIC interpreter is a fully self-contained executable and does not need the Cassette BASIC ROM found in the original. It was bundled with MS-DOS operating systems on IBM PC–compatibles by Microsoft.
34-399: The language is suitable for simple games, business programs and the like. Since it was included with most versions of MS-DOS, it was also a low-cost way for many aspiring programmers to learn the fundamentals of computer programming . Microsoft also sold a BASIC compiler , BASCOM, compatible with GW-BASIC, for programs needing more speed. According to Mark Jones Lorenzo, given the scope of
68-830: A COM file . Some variants of BASIC has extra features to support a particular machine. For example, the AT&T and Tandy versions of DOS include a special GW-BASIC that supports their enhanced sound and graphics capabilities. The initial version of GW-BASIC is the one included with Compaq DOS 1.13, released with the Compaq Portable in 1983, and was analogous to IBM BASICA 1.10. It uses the CP/M -derived file control blocks for disk access and does not support subdirectories. Later versions support subdirectories, improved graphics, and other capabilities. GW-BASIC 3.20 (1986) adds EGA graphics support (no version of BASICA or GW-BASIC had VGA support) and
102-452: A command-line -based integrated development environment (IDE) based on Dartmouth BASIC . Using the cursor movement keys, any line displayed on the screen can be edited. It also includes function key shortcuts at the bottom of the screen. Like other early microcomputer versions of BASIC, GW-BASIC lacks many of the structures needed for structured programming , such as local variables. GW-BASIC programs executed relatively slowly because it
136-483: A flight simulator . Simple programs can be written in a few hours. More complex ones may require more than a year of work, while others are never considered 'complete' but rather are continuously improved as long as they stay in use. In most cases, several programmers work together as a team under a senior programmer's supervision. Programming editors, also known as source code editors , are text editors that are specifically designed for programmers or developers to write
170-615: A character at the end of the variable name: A$ is a string of characters, A% is an integer , etc. Groups of variables can also be set to default types based on the initial letter of their name by use of the DEFINT , DEFSTR , etc., statements. The default type for undeclared variables not identified by such typing statements is single-precision floating-point ( 32-bit MBF ). GW-BASIC allows use of joystick and light pen input devices. GW-BASIC can read from and write to files and COM ports ; it can also do event trapping for ports. Since
204-450: A demand for software. Many of these programs were written in-house by full-time staff programmers; some were distributed between users of a particular machine for no charge, while others were sold on a commercial basis. Other firms, such as Computer Sciences Corporation (founded in 1959), also started to grow. Computer manufacturers soon started bundling operating systems , system software and programming environments with their machines;
238-421: A further decline of -9 percent from 2019 to 2029, a decline of -10 percent from 2021 to 2031. and then a decline of -11 percent from 2022 to 2032. Since computer programming can be done from anywhere in the world, companies sometimes hire programmers in countries where wages are lower. However, for software developers BLS projects for 2019 to 2029 a 22% increase in employment, from 1,469,200 to 1,785,200 jobs with
272-402: A lack of general interest in science and mathematics and also out of an apparent fear that programming will be subject to the same pressures as manufacturing and agriculture careers. For programmers, the U.S. Bureau of Labor Statistics (BLS) Occupational Outlook originally predicted a growth for programmers of 12 percent from 2010 to 2020 and thereafter a decline of -7 percent from 2016 to 2026,
306-566: A length in clock ticks for the standard internal PC speaker in IBM machines. Consequently, sound is limited to single channel beeps and whistles as befits a "business" machine. GW-BASIC for the Tandy ;1000 allows up to three channels of sound for the SOUND and PLAY commands. There are several theories on what the initials "GW" represent. Greg Whitten , an early Microsoft employee who developed
340-414: A median base salary of $ 110,000 per year. This prediction is lower than the earlier 2010 to 2020 predicted increase of 30% for software developers. Though the distinction is somewhat ambiguous, software developers engage in a wider array of aspects of application development and are generally higher skilled than programmers, making outsourcing less of a risk. Another reason for the decline for programmers
374-409: A programmer, although professional certifications are commonly held by programmers. Programming is considered a profession . Programmers' work varies widely depending on the type of business for which they are writing programs. For example, the instructions involved in updating financial records are very different from those required to duplicate conditions on an aircraft for pilots training in

#1732869679877408-648: A programmer. Generally, a programmer writes code in a computer language and with an intent to build software that achieves some goal . Sometimes a programmer or job position is identified by the language used or target platform. For example, assembly programmer , web developer . The job titles that include programming tasks have differing connotations across the computer industry and to different individuals. The following are notable descriptions. A software developer primarily implements software based on specifications and fixes bugs . Other duties may include reviewing code changes and testing . To achieve
442-438: A team of programmers, communicating with customers, managers and other engineers, considering system stability and quality, and exploring software development methodologies. Sometimes, a software engineer is required to have a degree in software engineering, computer engineering , or computer science. Some countries legally require an engineering degree to be called engineer . British countess and mathematician Ada Lovelace
476-409: A working, program-controlled, electronic computer. From 1943 to 1945, per computer scientist Wolfgang K. Giloi and AI professor Raúl Rojas et al., Zuse created the first, high-level programming language , Plankalkül . Members of the 1945 ENIAC programming team of Kay McNulty , Betty Jennings , Betty Snyder , Marlyn Wescoff , Fran Bilas and Ruth Lichterman have since been credited as
510-511: Is often considered to be the first computer programmer. She authored an algorithm , which was published in October 1842, for calculating Bernoulli numbers on the Charles Babbage analytical engine . Because the machine was not completed in her lifetime, she never experienced the algorithm in action. In 1941, German civil engineer Konrad Zuse was the first person to execute a program on
544-448: Is the last major new version released before it was superseded by QBasic . Buyers of Hercules Graphics Cards received a special version of GW-BASIC on the card's utility disk that is called HBASIC, which adds support for its 720×348 monochrome graphics. Other versions of BASICA/GW-BASIC do not support Hercules graphics and can only display graphics on that card through the use of third-party CGA emulation, such as SIMCGA. GW-BASIC has
578-548: Is their skills are being merged with other professions, such as developers, as employers increase the requirements for a position over time. Then there is the additional concern that recent advances in artificial intelligence might impact the demand for future generations of Software professions. As of 2024 in Japan , the demand for programmers is increasing rapidly. Numerous programming schools have opened to meet this demand, including TechAcademy , Tech i.s. and NinjaCode . On
612-518: The 8088 assembler source code for GW-BASIC 1.0 on GitHub under the MIT License . IBM BASICA and GW-BASIC are largely ports of MBASIC version 5.x, but with added features specifically for the IBM ;PC hardware. Common features of BASIC-80 5.x and BASICA/GW-BASIC include: The ability to "crunch" program lines by omitting spaces, a common feature of earlier Microsoft BASIC implementations,
646-583: The IBM 1620 came with the 1620 Symbolic Programming System and FORTRAN . The industry expanded greatly with the rise of the personal computer (PC) in the mid-1970s, which brought computing to the average office worker. In the following years, the PC also helped create a constantly growing market for games, applications and utility software. This resulted in increased demand for software developers for that period of time. Computer programmers write, test, debug , and maintain
680-469: The cassette tape port interface of the original IBM PC was never implemented on compatibles, cassette operations are not supported. GW-BASIC can play simple music using the PLAY statement, needing a string of notes represented in a music macro language , e.g., PLAY "edcdeeL2edfedL4c" . More low-level control is possible with the SOUND statement, which takes the arguments of a frequency in hertz and
714-606: The current program, or quit to the operating SYSTEM ; these commands can also be used as program statements. There is little support for structured programming in GW-BASIC. All IF / THEN / ELSE conditional statements must be written on one line, although WHILE / WEND statements may group multiple lines. Functions can only be defined using the single line DEF FNf (x)= <mathematical function of x> statement (e.g., DEF FNLOG(base,number)=LOG(number)/LOG(base) ). The data type of variables can be specified with

#1732869679877748-409: The detailed instructions, called computer programs , that computers must follow to perform their functions. Programmers also conceive, design, and test logical structures for solving problems by computer. Many technical innovations in programming — advanced computing technologies and sophisticated new languages and programming tools — have redefined the role of a programmer and elevated much of
782-576: The first professional computer programmers. The first company founded specifically to provide software products and services was the Computer Usage Company in 1955. Before that time, computers were programmed either by customers or the few commercial computer manufacturers of the time, such as Sperry Rand and IBM . The software industry expanded in the early 1960s, almost immediately after computers were first sold in mass-produced quantities. Universities, governments, and businesses created
816-449: The initials' origins include "Graphics and Windows", " Gates, William " (Microsoft's president at the time), or "Gates–Whitten" (the two main designers of the program). Programmer A programmer , computer programmer or coder is an author of computer source code – someone with skill in computer programming . The professional titles software developer and software engineer are used for jobs that require
850-436: The language, "GW-BASIC is arguably the ne plus ultra of Microsoft's family of line-numbered BASICs stretching back to Altair BASIC — and perhaps even of line-numbered BASIC in general." With the release of MS-DOS 5.0, GW-BASIC's place was taken by QBasic , a slightly abridged version of the interpreter part of the separately available QuickBASIC interpreter and compiler package. On May 21, 2020, Microsoft released
884-486: The other hand, despite the fact that there are more than 1.2 million programmers in Japan as of 2020, more than 40% of Japanese companies say they do not have enough IT personnel, including programmers; by 2030, the number of programmers will exceed 1.6 million, but about 800 000 people, including programmers A shortage of engineers is expected to occur. Interpreted language Too Many Requests If you report this error to
918-434: The programming work done today. Job titles and descriptions may vary, depending on the organization. Programmers work in many settings, including corporate information technology (IT) departments, big software companies , small service firms and government entities of all sizes. Many professional programmers also work for consulting companies at client sites as contractors . Licensing is not typically required to work as
952-483: The required skills for the job, they might obtain a computer science or associate degree, attend a programming boot camp or be self-taught . A software engineer usually is responsible for the same tasks as a developer plus broader responsibilities of software engineering including architecting and designing new features and applications, targeting new platforms, managing the software development lifecycle (design, implementation, testing, and deployment), leading
986-456: The source code of an application or a program. Most of these editors include features useful for programmers, which may include color syntax highlighting , auto indentation, auto-complete , bracket matching, syntax check , and allows plug-ins . These features aid the users during coding, debugging and testing. According to BBC News , 17% of computer science students could not find work in their field six months after graduation in 2009 which
1020-471: The standards in the company's BASIC compiler line, says that Bill Gates picked the name GW-BASIC. Whitten refers to it as Gee-Whiz BASIC and is unsure whether Gates named the program after him. The Microsoft User Manual from Microsoft Press also refers to it by the Gee-Whiz BASIC name. It may have also been nicknamed Gee-Whiz because of its numerous graphics commands. Other common theories as to
1054-451: Was an interpreted language . All program lines must be numbered; all non-numbered lines are considered to be commands in direct mode to be executed immediately. Program source files are normally saved in binary compressed format with tokens replacing keywords, with an option to save in ASCII text form. The GW-BASIC command-line environment has commands to RUN , LOAD , SAVE , LIST
GW-BASIC - Misplaced Pages Continue
1088-510: Was normally not enabled and required the optional parameter /D at startup, i.e., GWBASIC /D . BASIC's memory footprint was slightly increased if it was used. Microsoft did not offer a generic version of MS-DOS until v3.20 in 1986; before then, all variants of the operating system were OEM versions. Depending on the OEM, BASIC was distributed as either BASICA.EXE or GWBASIC.EXE. The former should not be confused with IBM BASICA, which always came as
1122-727: Was removed from BASIC-80 5.x and BASICA/GWBASIC. BASIC-80 programs not using PEEK / POKE statements run under GW-BASIC. BASICA adds many features for the IBM PC such as sound, graphics, and memory commands. Features not present in BASIC-80 include the ability to execute the RND function with no parameters and the ability to also save programs in a "protected" format, preventing them from being LIST ed. BASICA also allows double-precision numbers to be used with mathematical and trigonometric functions such as COS , SIN , and ATN , which wasn't allowed in 8-bit versions of BASIC. This feature
1156-600: Was the highest rate of the university subjects surveyed while 0% of medical students were unemployed in the same survey. After the crash of the dot-com bubble (1999–2001) and the Great Recession (2008), many U.S. programmers were left without work or with lower wages. In addition, enrollment in computer-related degrees and other STEM degrees (STEM attrition) in the US has been dropping for years, especially for women, which, according to Beaubouef and Mason, could be attributed to
