			Sedt Version 3.3

		    Author: Anker Berg-Sonne


	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.

                ATARI ST

		   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.

        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:

        C>MD \SEDT
        C>CD \SEDT
        C>COPY A:*.*
        C>COPY A:*.EDT *.TXT
        CD \
        PATH C:\;C:\SEDT
        SET SEDT=C:\SEDT\^Z

        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

        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
        GSEDT.PRG is intended to be run from the GEM desktop  and
uses  windows,  mouse  and  menus,  but  does  not accept command
        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.

		   Installation Instructions


	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$VK100help as Sedt$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.

			 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.
