Rapid-Q is a semi-OO multiplatform GUI/CONSOLE BASIC Compiler For Windows, Linux and several Unix flavours. It directly supports DirectX, Direct3D, MySQL, Sockets, CGI, and IDE w/Form designer. Its syntax is relatively close to QBasic, so porting your code shouldn't take long. No extra runtimes involved, the interpreter is embedded. Project is no longer in development, however, it's still great for writing everyday Windows applications.

Unlike the primary RapidQ group, this one is moderated - so no flame wars and no off-topic posts. We are willing to seriously discuss different aspects of using Rapid-Q, and strongly encourage you to do the same.
