Multiple Files: The Ring
    -------------------------------------------------------------------------

    QEdit is a true multi-file editor.  It allows as many files as will
    fit into memory to be loaded at the same time.  All of these files
    can then be edited by simply switching back and forth between them
    without having to save and load each file individually. Switching
    between files is accomplished very quickly and easily.

    A simple explanation of how QEdit handles multiple files will help
    you in manipulating and editing multiple files.

    QEdit maintains all loaded files in a "ring".  As we describe each
    of the commands used to manipulate the files in the ring, refer to
    the illustration below.

                      +---+                     +---+
              +------.| A |.----------<Ctrl KP> | B | <Alt N>
              .       +---+                     +---+       .
            +---+       .                      <Alt E>    +---+
            | F |.------+-------------------------+------.| C |
            +---+       .                         .       +---+
              .       +---+                     +---+       .
              +------.| E |.-------------------.| D |.------+
                      +---+                     +---+

    In the ring we see that six files have been loaded into the editor.
    You can, of course, load many more files - as many as your
    computer's memory will allow.

    Assume the file currently being edited is file "B".  You may then
    move from one file to another in any of the following ways:

    . Enter the NextFile <Alt N> command.
      You will now be editing the next file in the ring, file "C".

    . Enter the PrevFile <Ctrl KP> command.
      You will now be editing the previous file in the ring, file "A".

    . Enter the EditFile <Alt E> command.
      The editor will prompt for a filename.  You may enter the name of
      any file in the ring.  The editor will make the entered file the
      current one for editing.

    You may, at any time, add files to the ring or discard files from
    the ring.  If you add a new file to the ring using the EditFile
    command, it will become the current file and the old current file
    will become the previous file.  If you delete a file from the ring
    the previous file will become the current file.

    | QEdit Tip:                      |
    |   When loading files, be aware  |
    |   that QEdit will not load two  |
    |   copies of the same file.  If  |
    |   you issue the EditFile command|
    |   for a file already loaded,    |
    |   that file will become the     |
    |   new current file.             |
