SEDT
Sedt Version 3.3
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 has been developed in my spare time as a hobby. I
cannot provide any formal support or distribution but will be
happy to help on a best effort basis if you mail your request to
me with a self addressed, postage stamped envelope. Requests
should be mailed to Anker Berg-Sonne, 8 Middlemost Way, Stow, MA
01775, U.S.A.. Because of a lack of income from Sedt I cannot
provide floppy disks or other media.
If you have no other way to obtain Sedt for the ATARI ST
and IBM PC and compatibles, mail $25 to me at the above address
and I will mail you the most recent version.

Distribution Policy
Sedt binaries are being made available for customers and
Digital internal use on the condition that the original copyright
is not violated or removed, and that no modifications are made to
the program without express permission from me.
Current versions are maintained on the Digital internal
network and may be copied and distributed outside of Digital.
On a regular basis updates will be copied to the DECUS library.
Sedt is currently available in the following versions:
Rainbow 100: MS-DOS
VAXmate: MS-DOS
IBM PC and compatibles: MS-DOS
IBM Convertible: MS-DOS

Installation Instructions
Rainbow CP/M
Copy the contents of the CP/M program disk onto your
system disk in user area 0.
If you prefer the Gold keypad layout copy all the .GLD
files into .TXT files. E.g.
PIP *.TXT=*.GLD
If you want to revert to the EDT keyboard layout copy all
.EDT files into .TXT files. E.g.
PIP *.TXT=*.EDT
After choosing the keyboard layout you can conserve disk
space by deleting all .GLD and .EDT files.
�
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:*.*
Copy all .EDT files from the program disk into the
current directory as .TXT files. E.g.
COPY A:*.EDT A:*.TXT
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:*.*
C>COPY A:*.EDT *.TXT
CD \
COPY CON: AUTOEXEC.BAT
DATE
TIME
PATH C:\;C:\SEDT
SET SEDT=C:\SEDT\^Z
C>
If you prefer the Gold keyboard layout copy all .GLD
files to .TXT files. Note that Gold keyboard layouts and help
files are only implemented for Digital keyboards. E.g.
COPY *.GLD *.TXT
To revert back to the EDT keyboard layout copy all .EDT
files into .TXT files. E.g.
COPY *.EDT *.TXT
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.

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$Library:2XXhelp.Edt
Sedt$VK100keys as Sedt$Library:VK100keys.Edt
Sedt$VK100help as Sedt$Library:VK100help.Edt
If you use the WPS keypad define the logical names
Sedt$VT1XXkeys as Sedt$Library:VT1XXkeys.Gld
Sedt$VT1XXhelp as Sedt$Library:VT1XXhelp.Gld
Sedt$VT2XXkeys as Sedt$Library:VT2XXkeys.Gld
Sedt$VT2XXhelp as Sedt$Library:VT2XXhelp.Gld
Sedt$VK100keys as Sedt$Library:VK100keys.Gld
Sedt$VK100help as Sedt$Library:VK100help.Gld
Define the logical name Sedt$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
Assign Sedt$Library:VK100keys.Edt Sedt$VK100keys
Assign Sedt$Library:VK100help.Edt Sedt$VK100help

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.
