== User Interface ==
The User Interface (UI) of FutureOS presents the user with three sections: an the icon section (upper half of screen), a the file window (lower half of screen) and a the message line (bottomof screen). It appears directly after starting FutureOS, but can also be used by applications. The user can browse through directories of discs and hard-disc partitions. The size of the text window is fixed, so due to this 64 different file names can be displayed at once (this equals one complete directory of a data of system formatted disc f.e.). Instead of scrolling, you browse page by page throught through the used directories. A mouse pointer is used to select devices, functions or files; this pointer can be controlled with nearly all of the pointer based HID devices (joystick, mouse, trackball, light-pen, grafpadetc.) available for the CPC.
Applications can call the UI as a subroutine, and the user can return returns to the application via using the OK buttonicon. The icons are fixed, so therefore the layout remains stable throughout its use and on every CPC using FutureOS.
Files can be viewed on-screen (scroll up and down) or printed. When typing a text file it is possible to set the number of columns and lines of the window the text is displayed in.
