What program should you use to make ASCII artwork?

    You can create ASCII art in any text editor,    
    such as: Notepad in Windows,
    SimpleText or BBEdit in MacOS,
    nedit, vi, vim, or pico in Unix,                   _+m"m+_
    BEd or AZ in AmigaOS, edit in DOS,                Jp     qh
    or any of the various Emacs editors.              O       O
                                                      Yb     dY
    A  'quick-start'  program  for learning            "Y5m2Y"
    is JavE, a free Java program  that can be
    obtained from:-          http://www.jave.de

    Some editors have features which make them more
    suitable for  ASCII art  than others, but that is
    largely a matter of personal opinion. Features which
    are both useful for  ASCII art  and  available in many
    text editors, include the following:-

    *   Overtype, also known as overstrike: removes the need for
        you to constantly realign characters using the  Backspace,
        Space, and Delete keys. Try the  Insert key if there is one
        on your keyboard,  or  your program's Options or Preferences.

    *   Rectangular copy and paste: allows you to select rectangular
        sections of text (not just rows or parts of rows). On programs
        which have this feature, it is usually done by holding down a
        key such as Ctrl while selecting text.

    *   Find/Change: allows you to change all the characters of one
        value to another (eg: change all the ~s to "s).
