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
WHEN DOWNLOADING THEM YOU SHOULD SET THE FILE TYPE TO BINARY OR IMAGE,
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.
Information on updates is contained in the file aaaupdat, if it
Information on copyright is in the file copyright.
If you use this program, or have comments, let me know, preferably
by e-mail to the address above. Any further development of ET depends
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
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
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
Experienced users will of course be able to modify these instructions as
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
the ET.EXE, VESA16.BGI, ET.HLP, ET.MAC, ETTOTEX.EXE and TEXTOET.EXE.
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.
The contents of the distribution disk are:
README This file
ET.EXE The editor.
VESA16.BGI Auxiliary file needed to handle graphics
ET.HLP Help file for ET.
ET.MAC Standard macro definitions.
ETDOC.ET Documentation for ET.
ETTOTEX.EXE Converts ET file to TeX.
TEXTOET.EXE Converts TeX file to ET.
PRET.EXE Prints out draft quality version
of ET files on EPSON compatible
PRET1.EXE An improved version of the PRET
program, for printing out draft
quality versions of ET files. It
has not been completely checked out
though. Run PRET1 /HELP to see the
GRKDRAFT.PPR Downloadable printer font used
by PRET, no longer essential.
KEYS.ET When printed out using PRET, or
displayed on screen using ET,
shows the keyboard definition
for the Greek/symbol font.
TEXCORR.ET When printed out using PRET or
displayed on screen using ET,
shows the correspondence between
the Greek/symbol font and the
translation to TeX.
ETINST.EXE Program to customize keyboard
definition and help file for ET.
ET.TXT Uncustomized help file.
ETMACS.TEX Macros that let TeX directly
handle ET files.
HW2.ET Example of ET file that is used
only for draft print out by PRET
and not with TeX.
PAPER.ET Example file: a physics paper using ET.
ET2TEXC.C Source code in ANSI C for ET to TeX converter.
Can be used to implement ETTOTEX on another
ETDEFS.H Include file for ET2TEXC.C
ETTRAN.INC Include file for ET2TEXC.C
ET2TEXKR.C Kernighan and Ritchie C source code for
ETTOTEX -- old-fashioned C. Can be compiled
with standard UNIX C compiler.
LATER.EXE Program for comparing the date
and time of two files. Useful
in batch files for to avoid
overwriting a new file by an
old file in conversions. The
will explain how to use it.
