Qbasic is the extension of which programming language?
QBasic, a short form of Quick Beginners All purpose Symbolic Instruction Code, is an integrated development environment (IDE) and interpreter for a variety of BASIC programming languages which are based on QuickBASIC. Code entered into the IDE is compiled to an intermediate representation (IR), and this IR is immediately interpreted on demand within the IDE. It can run under nearly all versions of DOS and 32-bit versions of Windows, or through emulation via DOSBox/DOSEMU on Linux, FreeBSD, and 64-bit versions of Windows. (QBasic is a DOS program and requires DOS or a DOS emulator. Windows XP comes with an emulator called DOS Virtual Machine, subsequent versions of Windows require an emulator such as DosBox.) 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. It supports various inbuilt functions.
What programming language is Qbasic based on?
QuickBASIC
QBasic
QBasic was intended as a replacement for GW-BASIC. It was based on the earlier QuickBASIC 4.5 compiler but without QuickBASIC's compiler and linker elements. Version 1.0 was shipped together with MS-DOS 5.0 and higher, as well as Windows 95, Windows NT 3.x, and Windows NT 4.0. IBM recompiled QBasic and included it in PC DOS 5.x, as well as OS/2 2.0 onwards. eComStation, descended from OS/2 code, includes QBasic 1.0 . QBasic 1.1 is included with MS-DOS 6.x, and, without codice_1, in Windows 95, Windows 98 and Windows Me. Starting with Windows 2000, Microsoft no longer includes QBasic with their operating systems, but can still be obtained for use on newer versions of Windows.
