About Microsoft QuickBASIC

Microsoft QuickBASIC (also QB; not to be confused with "QBasic") is an Integrated Development Environment (or IDE) and compiler for the BASIC programming language. 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.
