GW-BASIC
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. 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 the language, "GW-BASIC is arguably the ''List_of_Latin_phrases_(N)#ne_plus_ultra, 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."

IBM Cassette BASIC
The IBM Personal Computer BASIC, commonly shortened to IBM BASIC, is a programming language first released by IBM with the IBM Personal Computer, Model 5150 (IBM PC) in 1981. IBM released four different versions of the Microsoft BASIC interpreter, licensed from Microsoft for the PC and PCjr. They are known as Cassette BASIC, Disk BASIC, Advanced BASIC (BASICA), and Cartridge BASIC. Versions of Disk BASIC and Advanced BASIC were included with IBM PC DOS up to PC DOS 4. In addition to the features of an ANSI standard BASIC, the IBM versions offered support for the graphics and sound hardware of the IBM PC line. Source code could be entered with a full-screen editor, and limited facilities were provided for rudimentary program debugging. IBM also released a version of the Microsoft BASIC compiler for the PC concurrently with the release of PC DOS 1.10 in 1982.

BASIC Interpreter
A BASIC interpreter is an Interpreter (computing), interpreter that enables users to enter and run programs in the BASIC programming language, language and was, for the first part of the microcomputer era, the default Application software, application that computers would launch. Users were expected to use the BASIC interpreter to type-in programs, type in programs or to load programs from storage (initially cassette tapes then floppy disks). BASIC interpreters are of historical importance. Microsoft's first product for sale was a BASIC interpreter (Altair BASIC), which paved the way for the company's success. Before Altair BASIC, microcomputers were sold as kits that needed to be programmed in machine code (for instance, the Apple I). During the Altair period, BASIC interpreters were sold separately, becoming the first software sold to individuals rather than to organizations; Apple BASIC was Apple's first software product. After the Altair 8800, MITS Altair 8800, microcomputers w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QBasic
QBasic is an integrated development environment (IDE) and BASIC interpreter, interpreter for a variety of dialects of BASIC which are based on QuickBASIC. Code entered into the IDE is compiled into an intermediate representation (IR), and this IR is immediately executed on demand within the IDE. Like QuickBASIC, but unlike earlier versions of Microsoft BASIC, QBasic is a structured programming language, supporting constructs such as subroutines. Line numbers, a concept often associated with BASIC, are supported for compatibility but are not considered good form, having been replaced by descriptive line labels. QBasic has limited support for user-defined data types (record (computer science), structures), and several primitive types used to contain strings of text or numeric data. It supports various inbuilt functions. For its time, QBasic provided a state-of-the-art IDE, including a debugger with features such as on-the-fly expression evaluation and code modification.

QuickBASIC
Microsoft QuickBASIC (also QB) is an Integrated Development Environment (or IDE) and compiler for the BASIC programming language that was developed by Microsoft. QuickBASIC runs mainly on DOS, though there was also a short-lived version for the classic Mac OS. It is loosely based on GW-BASIC but adds user-defined types, improved programming structures, better graphics and disk support and a compiler in addition to the BASIC interpreter, interpreter. Microsoft marketed QuickBASIC as the introductory level for their BASIC Professional Development System. Microsoft marketed two other similar IDEs for C and Pascal, viz QuickC and QuickPascal. History Microsoft released the first version of QuickBASIC on August 18, 1985 on a single 5.25-inch 360 KB floppy disk. QuickBASIC version 2.0 and later contained an Integrated Development Environment (IDE), allowing users to edit directly in its on-screen text editor. Although still supported in QuickBASIC, line numbers became optional. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MSX BASIC
MSX BASIC is a dialect of the BASIC programming language. It is an extended version of Microsoft's MBASIC Version 4.5, adding support for graphic, music, and various peripherals attached to MSX microcomputers. Generally, MSX BASIC is designed to follow GW-BASIC, released the same year for IBM PCs and clones. During the creation of MSX BASIC, effort was made to make the system flexible and expandable. Distribution MSX BASIC came bundled in the Read-only memory, ROM of all MSX computers. At system start-up MSX BASIC is invoked, causing its command prompt to be displayed, unless other software placed in Read-only memory, ROM takes control (which is the typical case of ROM cartridge, game cartridges and disk interfaces, the latter causing the MSX-DOS prompt to be shown if there is a disk present which contains the DOS system files). When MSX BASIC is invoked, the ROM code for BIOS and the BASIC interpreter itself are visible on the lower 32K of the Zilog Z80, Z80 addressing space. ...

Enhanced Graphics Adapter
The Enhanced Graphics Adapter (EGA) is an IBM PC compatible, IBM PC Video card, graphics adapter and ''de facto'' computer display standard from 1984 that superseded the Color Graphics Adapter, CGA standard introduced with the IBM Personal Computer, original IBM PC, and was itself superseded by the Video Graphics Array, VGA standard in 1987. In addition to the original EGA card manufactured by IBM, many compatible third-party cards were manufactured, and EGA graphics modes continued to be supported by VGA and later standards. History EGA was introduced in October 1984 by IBM,High-Resolution Standard Is Latest Step in DOS Graphics Evolution, ''InfoWorld'', June 26, 1989, p. 48.News Briefs, Big Blue Turns Colors, ''InfoWorld'', October 8, 1984. shortly after its new IBM Personal Computer AT, PC/AT.

Altair BASIC
Altair BASIC is a discontinued interpreter for the BASIC programming language that ran on the MITS Altair 8800 and subsequent S-100 bus computers. It was Microsoft's first product (as Micro-Soft), distributed by MITS under a contract. Altair BASIC was the start of the Microsoft BASIC product range. Origin and development Bill Gates recalls that, when he and Paul Allen read about the Altair in the January 1975 issue of '' Popular Electronics'', they understood that the price of computers would soon drop to the point that selling software for them would be a profitable business. "While walking through Harvard Square one day, Allen spotted the Popular Electronics cover that features the Altair. ... Allen ran to tell Bill that he thought their big break had finally come. Bill agreed." Gates believed that, by providing a BASIC interpreter for the new computer, they could make it more attractive to hobbyists. They contacted MITS founder Ed Roberts, told him that they were developi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
