Changes

Filenames can use all 256 different characters and user numbers from 0 to 254 (except for &E5, which marks a deleted file). Different to Amsdos, a file that is erased under FutureOS will not be shifted to user &E5, but it will be physically removed from the directory. Files can be viewed on-screen (scroll up and down) or printed. You can also view the file-header. When typing a text-file it is possible to set the number of columns and lines of the window the text is displayed in. File-headers are displayed as AmsDOS file or the icon-like file-header of a FutureOS program. An AmsDOS file-header has 128 bytes of which some bytes are unused. FutureOS makes use of those unused bytes so that files have a length definition of 24bit and can have a physical RAM select. Therefore a file can be defined to be loaded everywhere in the external RAM. Also a FutureOS file-header can contain a graphical icon, a textual icon or a short description of the file. FutureOS work with old AmsDOS file-headers.
