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 C++ emitter, which is integrated with a C++ compiler to provide compilation via C++ code and GCC optimization.[2]
QB64 implements most QBasic statements, and can run many QBasic programs, including Microsoft’s QBasic Gorillas and Nibbles games.[3] Furthermore, QB64 has been designed to contain an IDE resembling the QBASIC IDE. QB64 also extends the QBASIC programming language to include 64-bit data types, as well as better sound and graphics support. It can also emulate some DOS/x86 specific features such as INT 33h mouse access, and timers.



FreeBASIC is a free/open source (GPL), BASIC compiler for Microsoft Windows, DOS and Linux.
The FreeBASIC project is a set of cross-platform development tools initially created by Andre Victor, consisting of a compiler, GNU-based assembler, linker and archiver, and supporting runtime libraries, including a software-based graphics library. The compiler, fbc, currently supports building for i386-based architectures on the DOS, Linux, Windows and Xbox platforms. The project also contains thin bindings (header files) to some popular 3rd party libraries such as the C runtime library, Allegro, SDL, OpenGL, GTK+, the Windows API and many others, as well as example programs for many of these libraries.
FreeBASIC is a high-level programming language supporting procedural, object-orientated and meta-programming paradigms, with a syntax compatible to Microsoft QuickBASIC. In fact, the FreeBASIC project originally began as an attempt to create a code-compatible, free alternative to Microsoft QuickBASIC, but it has since grown into a powerful development tool. FreeBASIC can be seen to extend the capabilities of Microsoft QuickBASIC in a number of ways, supporting more data types, language constructs, programming styles, and modern platforms and APIs.
Any type of program can be written with FreeBASIC, see our Gallery of Applications for some notable examples.


Fifty Years of BASIC, the Programming Language That Made Computers Personal

Time. 2014-04-29
I find the “everybody should learn to code” movement laudable. And yet it also leaves me wistful, even melancholy. Once upon a time, knowing how to use a computer was virtually synonymous with knowing how to program one. And the thing that made it possible was a programming language called BASIC.
