Visual Basic for DOS: Building Scientific and Technical Applications
Visual BASIC for DOS (VBDOS) is ideally suited for work in the physical science laboratory because access to serial ports and interface cards is much easier than other languages. It doesn't require line numbers, has subprograms which permit the passing of arguments, allows global and local variables, separate compilation of routines and linking of libraries and more. VBDOS provides a way for users to effectively process, acquire and display technical data.
