Later versions of Visual Basic did not include DOS versions, as Microsoft concentrated on Windows applications. A subset of QuickBASIC 4.5, named QBasic, was included with MS-DOS 5 and later versions, replacing the GW-BASIC included with previous versions of MS-DOS. Compared to QuickBASIC, QBasic is limited to an interpreter only, lacks a few ...
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.

QB64 (originally QB32) [1] is a self-hosting BASIC compiler for Microsoft Windows, Linux and Mac OS X, designed to be compatible with Microsoft QBasic and QuickBASIC. QB64 is a transpiler to C++ , which is integrated with a C++ compiler to provide compilation via C++ code and GCC optimization.
QBasic 1.0 was included in MS-DOS 5.0, and in Windows NT 3.x and 4.0. These are three different compiles of the same: 5.00, 5.00a and WNT use different versions of QBASIC. IBM recompiled QBasic and included it in their IBMDOS 5.x, as well as OS/2 2.0 onwards. eComstation includes OS/2, and includes QBasic 1.0. There are four versions of this.
Bill Gates and Paul Allen were working on Altair BASIC in 1975. They were developing the software at Harvard University on a DEC PDP-10 running their Altair emulator. [9] One thing they lacked was code to handle floating-point numbers, required to support calculations with very big and very small numbers, [9] which would be particularly useful for science and engineering.
A convenient feature of Commodore's ROM-resident BASIC interpreter and KERNAL was the full-screen editor. [3] [4] Although Commodore keyboards only have two cursor keys which reversed direction when the shift key was held, the screen editor allowed users to enter direct commands or to input and edit program lines from anywhere on the screen.
Visual C++ 4.0 included MFC 4.0, was designed for Windows 95 and Windows NT. To allow support of legacy (Windows 3.x/DOS) projects, 4.0 came bundled with the Visual C++ 1.52 installation CD. Updates available through subscription included Visual C++ 4.1, which came with the Microsoft Game SDK (later released separately as the DirectX SDK), and ...
