MVL is a simple and compact (34 commands) general purpose language allowing inexperienced users to interact easily with the Windows environment. MVL users can: create customized windows; insert objects such as subwindows, menus, buttons and sliders; define the program response at mouse or menu events; perform calculations with numeric or string constants, variables and arrays. Language, IDE, Manual and ready-to-run Examples are integrated in a single file (mvl.exe, less than 500 Kb) that can be executed from any writable medium (no installation required).
