    Abstract:   Tests a system's text speed by:
        1)  using DOS to spit out X short and long lines of text
        2)  using BIOS to scroll the same data
        3)  using MSC's _outtext function to scroll the same data
        4)  using _outtext to scroll the data inside a window
        The user can set the video mode and the quantity of text.
