Sedt Version 4.0
Author: Anker Berg-Sonne
Description
Sedt is a screen editor written with the goal of
providing a common editor across a wide range of operating
systems. For ease-of-use Sedt is programmed with a keyboard
layout similar to EDT.
For a complete description of Sedt's features read the
documentation in SEDTMAN.EDT.
Sedt version 4.0 (151) is a shareware program and must be
properly licensed by paying a license fee.
Properly licensed users will receive support if they
submit a report in writing to the author, Anker Berg-Sonne, 8
Middlemost Way, Stow, MA 01775, U.S.A.
Distribution Policy
You may distribute Sedt freely by any means as long as
the License Agreement and all other files from the original
distribution are included.
Sedt may not be used beyond a one month trial period
without payment of a license fee.
The license fee includes ONE copy of Sedt for ONE
operating system. Additional copies and updates require payment
of a fee.
Sedt is currently available in the following versions:
MS-DOS for Rainbow 100
MS-DOS for VAXmate
MS-DOS for IBM PC/XT/AT and compatibles
MS-DOS for PS/2 and compatibles
MS-DOS Microsoft Windows for IBM PC/AT and compatibles
OS/2 protected mode
ATARI ST
VAX/VMS
VAX ULTRIX
SCO XENIX
Installation Instructions
Rainbow, IBM PCs and compatibles
MS-DOS and OS/2
Create a directory for the SEDT files using the DOS MD
command in the format "CD <drive>:\<directory>". E.g.
MD C:\SEDT
In this example C is the name of the drive and SEDT the
name of the directory that is being created.
Ensure that the directory you just created is your
default directory with the DOS CD command in the format "CD
\<directory>". E.g.
C:
CD \SEDT
Copy the all files from the program disk into the current
directory. E.g.
COPY A:*.*
If you are familiar with Sedt you can use it for the next
two steps.
Add the directory that contains the SEDT files to the
PATH command in AUTOEXEC.BAT on your boot drive in the format
";<Drive>:\<directory>". If there is no PATH command in
AUTOEXEC.BAT create one that contains the root directory on your
boot drive and the SEDT directory. E.g.
PATH C:\;C:\SEDT
Add a command to create an environment variable called
SEDT that points to the directory containing the SEDT files to
AUTOEXEC.BAT on your boot drive. E.g.
SET SEDT=C:\SEDT\
An example of a complete installation follows:
A>C:
C>MD \SEDT
C>CD \SEDT
C>COPY A:*.*
CD \
COPY CON: AUTOEXEC.BAT
DATE
TIME
PATH C:\;C:\SEDT
SET SEDT=C:\SEDT\^Z
C>
Once you have Sedt installed refer to the documentation
in SEDTMAN.EDT for instructions on how to customize Sedt.
Installation Instructions
ATARI ST
Install Sedt on you ATARI system by following the
instructions given below:
Your first action should be to make backup copies of the
Sedt disks. Use the backup copies from now on and only use the
Sedt disks to create new backup copies.
You can either use the backup copy to run Sedt from or
copy it's contents onto another disk or into a folder.
When you run Sedt from the GEM desktop you should run it
from the directory containing all of the files. Under GEM this
is done simply by opening a window to the directory and double
clicking the program.
If you intend to run Sedt from a shell processor, such as
the Mark Williams msh, you can install Sedt so that it can be
called from any directory without copying the files. Install the
directory that contains SEDT.TTP into the PATH environment
variable and also create a new environment variable, called SEDT,
that points to the directory containing STKEY.TXT and STHLP.TXT.
The command "setenv SEDT=C:\SEDT\" will cause Sedt to pick the
files out of directory \SEDT on drive C. Do not forget the last
backslash!
The program SEDT.TTP is intended to be run from a shell
processor and given command arguments. You can run it from GEM
and supply arguments, but it will not use windows, the mouse or
menus.
GSEDT.PRG is intended to be run from the GEM desktop and
uses windows, mouse and menus, but does not accept command
arguments.
Sedt is distributed on two single-sided 3 1/2" disks.
The first disk contains all files necessary to run Sedt
from a shell in command mode. The program on this disk,
SEDT.TTP, does not take advantage of GEM, but supports journaling
of keystrokes.
The second disk contains all files necessary to run Sedt
under GEM with full support of windows, mouse and menu. The
program on this disk, GSEDT.PRG, does not support command
arguments or keystroke journaling.
Installation disk 1 contains the following files:
SEDT.TTP Shell version of the Sedt program
STKEY.TXT Keyboard definition file for the ATARI
ST. This file MUST be resident in your
current directory when you call Sedt.
STHLP.TXT Help file for the ATARI ST. In order to
use the interactive help facility this
file must be resident in your current
directory when you call Sedt.
RULER0.TXT Default ruler file. For Sedt to load it
properly it must be resident in your
current directory when you call Sedt.
SEDTMAN.EDT Machine readable copy of Sedt's
documentation. This is a 100 page
document and should be read for a proper
understanding of Sedt.
README Distribution policy.
SEDT.DOC Revision history and installation
instructions.
Installation disk 2 contains the following files:
GSEDT.PRG GEM version of the Sedt program
SEDT.RSC Resource file for the GEM version of Sedt
STKEY.TXT Keyboard definition file for the ATARI
ST. This file MUST be resident in your
current directory when you call Sedt.
STHLP.TXT Help file for the ATARI ST. In order to
use the interactive help facility this
file must be resident in your current
directory when you call Sedt.
RULER0.TXT Default ruler file. For Sedt to load it
properly it must be resident in your
current directory when you call Sedt.

SEDT.DOC Revision history and installation
instructions.
Installation Instructions
VMS
Copy Sedt.Exe, Sedt.Com, *.Edt and *.Gld to a directory.
Define the logical name Sedt$Library to point to the directory,
the symbol Se*dt:==$Sedt$Library:Sedt and
KSe*dt:==@Sedt$Library:Sedt. You do not need write access to
Sedt$Library in order to use Sedt.
If you use the EDT keypad define the logical names
Sedt$VT1XXkeys as Sedt$Library:1XXkeys.Edt Sedt$VT1XXhelp as
Sedt$Library:1XXhelp.Edt Sedt$VT2XXkeys as
Sedt$Library:2XXkeys.Edt Sedt$VT2XXhelp as
Sedt$Library:2XXhelp.Edt
Define the logical name Sedt$Dir to point to a directory
which you have write access to. Saved rulers will be stored in
this directory. Until you have saved ruler 0 in this directory
you will get the message "Could not find ruler file" every time
you enter Sedt. Enter ruler mode, define your default ruler
settings and save them by typing Gold 0.
Example:
Assign Sys$Disk:[Mydir] Sedt$Library
Assign Sys$Disk:[Mydir] Sedt$Dir
Se*dt:==$Sedt$Library:Sedt
Assign Sedt$Library:1XXkeys.Edt Sedt$VT1XXkeys
Assign Sedt$Library:1XXhelp.Edt Sedt$VT1XXhelp
Assign Sedt$Library:2XXkeys.Edt Sedt$VT2XXkeys
Assign Sedt$Library:2XXhelp.Edt Sedt$VT2XXhelp
Appendix B
Installation Instructions
UNIX Systems
Copy sedt (the executable file) into a directory in the
path.
Copy the rest of the files in the distribution into any
directory that the users will have read access to, e.g.
/usr/lib/sedt
If you log into the Bourne shell include the following
into /etc/profile assuming you want to make Sedt available to
everybody, or in .profile in your directory if you just want to
use Sedt yourself (assuming you put the Sedt files in the
directory in the above example):
SEDT=/usr/lib/sedt
PSEDT=$HOME
export SEDT PSEDT
If you log into the C shell include the following in
.cshrc in your directory:
setenv SEDT /usr/lib/sedt
setenv PSEDT $HOME
The environment variable term must start with vt1, vt2,
ansi or vt52 for Sedt to be able to run.
Appendix B
Installation Instructions
Additional Instructions to enable using Sedt on the console
of PCs running SCO XENIX
To be able to use Sedt from the console of a PC running
SCO XENIX the keyboard must be remapped to emulate a VT200. This
will change the escape sequences sent by the keys. To enter
numeric values from the numeric keypad the Alt or Ctrl keys must
be held down. To change Num Lock Alt Num Lock must be typed.
If the PC has an old style AT keyboard:
Copy strings.at and keys.at to /usr/lib/keyboard
Copy ansat.key to ansikeys.edt
Copy ansat.hlp to ansihelp.edt
Include
mapstr /usr/lib/keyboard/strings.at
in /etc/profile.
Include
mapkey /usr/lib/keyboard/keys.at
/etc/rc
If the PC has an enhanced style keyboard (separate editing
keypad):
Copy strings.en and keys.en to /usr/lib/keyboard.
Copy ansen.key to ansikeys.edt
Copy ansen.hlp to ansihelp.edt
Include
mapstr /usr/lib/keyboard/strings.en
in /etc/profile.
Include
mapkey /usr/lib/keyboard/keys.en
/etc/rc
Ensure that Num Lock is on when Sedt is called. Num Lock
can be changed by typing Alt Num Lock.
The environment variable term must contain the value ansi
for Sedt to work properly from the console.
Known Problems
Under MS/DOS you may run out of files when using 3 to 4
concurrent buffers. You should increase the number of concurrent
files in CONFIG.SYS to at least 12. The symptom is either a
fatal message "Error creating buffer file" or non-fatal "Could
not open journal file" or "Could not open input file".
When on the MS/DOS versions the column number exceeds 64K
the display will become corrupted and Sedt may not be able to
recover. There are no plans to correct this problem.
