BASIC (an acronym for Beginner's All- purpose Symbolic Instruction Code). Kurtz designed the original BASIC language at Dartmouth College in New Hampshire. They wanted to enable students in fields other than science and mathematics to use computers. At the time, nearly all use of computers required writing custom software, which was something only scientists and mathematicians tended to learn. Versions of BASIC became widespread on microcomputers in the mid- 1. Microcomputers usually shipped with BASIC, often in the machine's firmware. Having an easy- to- learn language on these early personal computers allowed small business owners, professionals, hobbyists, and consultants to develop custom software on computers they could afford. In the 2. 01. 0s, BASIC remains popular in many computing dialects and in new languages influenced by BASIC, such as Microsoft's Visual Basic. In 2. 00. 6, 5. 9% of developers for the . NET Framework used Visual Basic . NET as their only programming language. Users submitted jobs (calculations or other requests) on punched cards or similar media to specialist computer operators. The computer stored these, then used a batch processing system to run this queue of jobs one after another, allowing very high levels of utilization of these expensive machines. As the performance of computing hardware rose through the 1. This allowed a mix of batch jobs to be run together, but the real revolution was the development of time- sharing. Time- sharing allowed multiple remote interactive users to share use of the computer, interacting with the computer from computer terminals with keyboards and teletype printers, and later display screens, in much the same way as desktop computers or personal computers would be used later. The original BASIC language was released on May 1, 1. John Kemeny and Thomas Kurtz. It was intended specifically for less technical users who did not have or want the mathematical background previously expected. Being able to use a computer to support teaching and research was quite novel at the time. The language was based on FORTRAN II, with some influences from ALGOL 6. Initially, BASIC concentrated on supporting straightforward mathematical work, with matrix arithmetic support from its initial implementation as a batch language, and character string functionality being added by 1. Wanting use of the language to become widespread, its designers made the compiler available free of charge. In the following years, as other dialects of BASIC appeared, Kemeny and Kurtz's original BASIC dialect became known as Dartmouth BASIC. Spread on minicomputers. The BASIC language was available for the Data General Nova, and also central to the HP Time- Shared BASIC system in the late 1. A version was a core part of the Pick operating system from 1. During this period a number of simple computer games were written in BASIC, most notably Mike Mayfield's Star Trek. A number of these were collected by DEC employee David H. Ahl and published in a newsletter he compiled. He later collected a number of these into book form, 1. BASIC Computer Games, published in 1. When management refused to support the concept, Ahl left DEC in 1. Creative Computing. The book remained popular, and was re- published on several occasions. It had the advantage that it was fairly well known to the young designers and computer hobbyists who took an interest in microcomputers. Despite Dijkstra's famous judgement in 1. He had seen BASIC on minicomputers and felt it would be the perfect match for new machines like the MITS Altair 8. How to design and implement a stripped- down version of an interpreter for the BASIC language was covered in articles by Allison in the first three quarterly issues of the People's Computer Company newsletter published in 1. Dr. Dobb's Journal of Tiny BASIC Calisthenics & Orthodontia: Running Light Without Overbyte. Versions were written by Li- Chen Wang and Tom Pittman. The first Altair version was co- written by Gates, Allen, and Monte Davidoff. Almost universally, home computers of the 1. ROM- resident BASIC interpreter, which the machines booted directly into. Upon boot, a BASIC interpreter in immediate mode was presented, not the command line interface used on systems running CP/M or MS- DOS. Commodore Business Machines included a version of Microsoft BASIC. The Apple II and TRS- 8. BASIC, a smaller introductory version introduced with the initial releases of the machines and a more advanced version developed as interest in the platforms increased. As new companies entered the field, additional versions were added that subtly changed the BASIC family. The Atari 8- bit family had its own Atari BASIC that was modified in order to fit on an 8 k. B ROM cartridge. The BBC published BBC BASIC, developed by Acorn Computers Ltd, incorporating many extra structured programming keywords and advanced floating- point operation features. As the popularity of BASIC grew in this period, computer magazines published complete source code in BASIC for video games, utilities, and other programs. Given BASIC's straightforward nature, it was a simple matter to type in the code from the magazine and execute the program. Different magazines were published featuring programs for specific computers, though some BASIC programs were considered universal and could be used in machines running any variant of BASIC (sometimes with minor adaptations). Many books of type- in programs were also available, and in particular, Ahl published versions of the original 1. BASIC games converted into the Microsoft dialect and published it from Creative Computing as BASIC Computer Games. This book, and its sequels, provided hundreds of ready- to- go programs that could be easily converted to practically any BASIC- running platform. Later packages, such as Learn to Program BASIC would also have gaming as an introductory focus. On the business- focused CP/M computers which soon became widespread in small business environments, Microsoft BASIC (MBASIC) was one of the leading applications. They sourced this from Microsoft - IBM Cassette BASIC - but Microsoft also produced several other versions of BASIC for MS- DOS/PC DOS including IBM Disk BASIC (BASIC D), IBM BASICA (BASIC A), GW- BASIC (a BASICA- compatible version that did not need IBM's ROM) and QBasic, all typically bundled with the machine. In addition they produced the Microsoft BASIC Compiler aimed at professional programmers. Turbo Pascal- publisher Borland published Turbo Basic 1. Power. BASIC). Microsoft wrote the windowing- based Amiga. BASIC that was supplied with version 1. GUI Amiga computers (late 1. Microsoft marks. These languages introduced many extensions to the original home- computer BASIC, such as improved string manipulation and graphics support, access to the file system and additional data types. More important were the facilities for structured programming, including additional control structures and proper subroutines supporting local variables. However, by the latter half of the 1. C and later C++ became the languages of choice for professional . This was an evolutionary development of Quick. Basic, and included constructs from other languages such as block structured control statements including . But the language retained considerable links to its past, such as the Dim statement for declarations, . An important driver for the development of Visual Basic was as the new macro language for Microsoft Excel, a spreadsheet program. Ironically, given the origin of BASIC as a . While many advanced programmers still scoffed at its use, VB met the needs of small businesses efficiently wherever processing speed was less of a concern than ease of development. By that time, computers running Windows 3. Many small business owners found they could create their own small, yet useful applications in a few evenings to meet their own specialized needs. Eventually, during the lengthy lifetime of VB3, knowledge of Visual Basic had become a marketable job skill. Microsoft also produced VBScript in 1. Visual Basic . NET in 2. The latter has essentially the same power as C# and Java but with syntax that reflects the original Basic language. Post- 1. 99. 0 versions and dialects. Modern commercial incarnations include Pure. Basic, Power. BASIC, Xojo, Monkey X and True BASIC (the direct successor to Dartmouth BASIC from a company controlled by Kurtz). Several web- based simple BASIC interpreters also now exist, including Quite BASIC and Microsoft's Small Basic (educational software). Versions of BASIC have been showing up for use on smartphones and tablets. Apple App Store contains such implementations of BASIC programming language as smart BASIC, Basic!, Hot. Paw Basic, BASIC- II, tech. BASIC and others. Android devices feature such implementations of BASIC as RFO BASIC and Mintoris Basic. Applications for some mobile computers with proprietary OS (Cipher. Lab) can be built with programming environment based on BASIC. An application for the Nintendo 3. DS and Nintendo DSi called Petit Computer allows for programming in a slightly modified version of BASIC with DS button support. A 3. DS sequel was released in Japan in November 2. Calculators. Prior to DOS 5, the Basic interpreter was GW- Basic. Quick. Basic is part of a series of three languages issued by Microsoft for the home and office power user and small scale professional development; Quick.
