BASIC beginner's all-purpose symbolic instruction code This standard, high-level family of programming languages is simple to learn but creates programs that are typically slow to use. Many types of BASIC are available--your package might be called Turbo, Quick, or Visual Basic. The language is not generally used for industrial-strength applications, although Visual Basic has spawned a lot of shareware programs--and even some commercial apps such as MicroHelp's Uninstaller.
