The files in this directory are for the ET editor, which runs on MSDOS
computers (including MS-Windows).  All the files are MSDOS files, and
as appropriate for your version of ftp.  (This is usually done by the
command binary in a UNIX version of ftp.)  The same remarks apply if
you are subsequently downloading the files to an MSDOS computer from
your mainframe or workstation (etc).  If you do not do this, the
executable files, in particular, will be badly corrupted.

If you use this program, or have comments, let me know, preferably

on user encouragement of the author!  However


To install ET on a hard disk, use the following procedure:

       1.  Choose, and, if necessary, create a directory on the hard
           disk to hold ET.  In the following, I will assume this
           directory is C:\ET.  This directory will be referred to as
           ET's home directory.
       2.  Ensure that this directory is in the MSDOS path.  Use the PATH
           command for this purpose.  Normally you will modify your
           AUTOEXEC.BAT file to do this.  This will ensure that ET can
           be run no matter what the default directory and drive are.
       3.  Copy the files on the distribution disk to ET's home
           directory. If the distribution disk is in drive A: and the ET
           home directory is C:\ET, then use the command
                        COPY A:*.* C:\ET
       4.  Change default drive and directory to ET's home directory,
           for example by the commands
                        CD \ET
       5.  To obtain the documentation, print out the file ETDOC.ET.
           This contains full information on installing and running ET.
           This printout can be obtained by the MSDOS command
                        PRINT ETDOC.ET
           or by the MSDOS command
                        COPY ETDOC.ET PRN
       6.  You now need to install ET itself.  First run ET by the command
           Now set the correct home directory for ET.  This will ensure
           that when you run ET it will know where to look to find the
           help file and the default macro file.
                (a) Use the F10 key to access the main menu.
                (b) Press the 'O' key to get the Options menu.
                (c) Press the 'L' key to get the Load File submenu.
                (d) Press the 'H' key to set the Home directory.
                (e) You will be prompted to enter the name (drive and
                    directory) of the home directory.  The current
                    directory's name will be given as the default (C:\ET
                    in our example); if this is satisfactory, press the
                    return key, otherwise type in the name, followed by
                    the return key.
                (f) Press the escape key to back up one level in the menu
                (g) Press the 'S' key to save this and other options for
                    ET in its executable file.  Thus the next time the
                    program is run, it will look in the home directory
                    for macro and help files.
                (h) When ET has finished saving the setup, it will
                    display a message.
                (i) Press the escape key to remove the message.
                (j) Press the escape key again to remove the Options
                (k) You should now be at the main menu.   Either type
                    'F' followed by 'Q' to quit ET, or press the escape
                    key to return to text editing.
                (l) If you choose to stay in ET to explore it, note that
                    the <F10> key gets you to the main menu when you are
                    editing text, that the escape key backs you up one
                    level in the menu system, and that the <F1> key will
                    get you help.
                (m) To exit ET, go to the File menu, and type 'Q' (for

Minimum files needed.  If you are short on disk space you may
eliminate a number of the files.  At an absolute minimum you can have
You will also need PRET.EXE if you plan to print in draft mode on a
dot matrix printer.  You can eliminate ET.HLP if you can get by
without online help; you can eliminate TEXTOET.EXE if you do not wish
to convert TeX files to ET, and you can eliminate ETTOTEX.EXE if you
do not plan to convert ET files to TeX on the computer you are using
to do the editting.

Whenever you configure ET to you different keystrokes for commands, you
will need the ETINST.EXE file and ET.TXT.
