QB64

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. QB64 (originally QB32) is a self-hosting BASIC compiler for Microsoft Windows and Linux, 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. QB64 implements most QBasic statements, and can run many QBasic programs, including Microsoft''s QBasic Gorillas and Nibbles games. 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. QB64 was originally compiled with QuickBASIC 4.5. After significant development, Galleon, the developer, became hindered by QuickBASIC''s memory limitations and switched to Microsoft Basic PDS 7.1, which solved these problems for a short time. After version 0.63, QB64 was able to compile itself so the Conventional memory limitations no longer applied.
