QBasic has limited support for user-defined data types ,⁶ and several primitive types used to contain strings of text or numeric data. [3] [4] 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.
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 functions, can only handle programs of a limited size, and lacks support for separate program modules.
Free and open-source software portal; 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. [2]
Aims at full compatibility with Microsoft QBasic and QuickBASIC. BASIC code is translated to C++ and then compiled to executable form. An event driven GUI builder named InForm exists for QB64. [69] QBasic (DOS on the PC) – by Microsoft. Subset of QuickBASIC. Came with versions of MS-DOS from 5.0 to 6.22. Also included with DOS 7 (what Windows ...
The successor to BASICA for MS-DOS and PC DOS versions, now discontinued, is QBasic, launched in 1991. It is a stripped-down version of the Microsoft QuickBASIC compiler: QBasic is an interpreter and cannot compile source files, while QuickBASIC can compile and save the programs in the .EXE executable file format.
In MS-DOS, it was a stub for QBasic running in editor mode. Starting with Windows 95, MS-DOS Editor became a standalone program because QBasic didn't ship with Windows. The Editor may be used as a substitute for Windows Notepad on Windows 9x, although both are limited to small files only.
QBasic 1.1 is included with MS-DOS 6.x, and, without EDIT, with Windows 9x. The edit.hlp files from v 1.0 and 1.1 have different linking codes, so requesting context-sensitve help where qbasic and edit.hlp are different versions will lead to incorrect pages. The help system is Quickhelp, a precursor to Winhelp.
