Sedt Version 4.2 (290)
Sedt Reference Manual
0 Introduction
The Advanced Guide attempts to take you logically through
the extremely rich command set of Sedt. Even though care has
been taken not to mention features without describing them, you
may find that you have to cross-reference different sections
before you fully understand a feature. The Reference section may
come in very useful for this purpose.
1 Entering Sedt
The complete syntax for calling Sedt is
SEDT {<Input File> {-o<Output file>}} {<Option>... }
The input file will be loaded into buffer number 0, which
is the editing buffer at start-up. If an output file is
specified, buffer 0 will be saved into the specified file by
default.
Options change the behavior of Sedt for the complete
editing session. A complete list of options follows:
1.1 -<Line Number>
After initialization Sedt will position
the cursor at the start of the line
number you provided. This function is
most useful for programmers that need to
go to a line number that the compiler has
passed a syntax error message for.
1.2 -a
Turns autosaves on for the editing
session. Autosaves ensures that your
file is saved at regular intervals in
case of a system crash. Autosaved copies
are stored in files with the extension
.AUS.
1.3 -at
Suppresses Sedt's automatic recognition
of the system and makes Sedt assume that
it is running on an IBM AT with the AT
keyboard. Use this when the recognition
code fails to recognize the system
properly.
1.4 -b
Suppresses the renaming of old versions
when files are saved. By default Sedt
will rename any existing file to .BAK on
the MS-DOS and ATARI versions before
writing the new version. This allows you
to recover from editing sessions where
you have accidentally corrupted the file.
On VMS there is no need for .BAK files
since VMS supports multiple generations
of files. Normally -b is used when disk
space is too tight for both the new file
and the backup.
1.5 -co
Suppresses Sedt's automatic recognition
of the system and makes Sedt assume that
it is running on a color system. Use
this when the recognition code fails to
recognize the system properly.
1.6 -e
Terminate all files written with an ASCII
SUB character. Some applications require
a SUB character to recognize the end of
data files.
1.7 -edt
Use the EDT style editing.
1.8 -ega
Switch the display into EGA 43 line mode
during the session and switch back into
25 line mode at the end.
1.9 -i<File Name>
Read internal Sedt commands from the
given file after initialization and
before accepting keyboard input. Using
the -i option prevents automatic
execution of the default initialization
file.
1.10 -k
Suppresses Sedt's automatic recognition
of the keyboard type and informs Sedt
that the system uses the enhanced IBM
keyboard.
-k<type>
Suppresses Sedt's automatic recognition
of the keyboard and forces Sedt to use
<type> as the prefix for keyboard map and
help files.
1.11 -l<Size>
Limits the main memory buffering of
information to <Size> bytes. This option
is used to ensure that enough memory is
left over to spawn sub-processes on
MS-DOS systems. This option has no
effect on other than MS-DOS
implementations.
1.12 -m<Hex number>
Changes the video mode of Sedt under DOS
to <Hex number>. Sedt will configure
itself for the correct number of lines
and columns supported by the selected
mode. On super VGA adapters mode 54 is
often 132 columns by 43 lines and mode 55
is often 132 columns by 25 lines.
1.13 -mo
Suppresses Sedt's automatic recognition
of the system and makes Sedt assume that
it is running on a monochrome system.
Use this when the recognition code fails
to recognize the system properly.
1.14 -p<PID>
Informs Sedt of the Process ID of the
parent process. This option is only used
on the VMS version of Sedt and creates a
resident version of Sedt. On exit Sedt
will attach to the parent process and
remain resident. Upon reattachment Sedt
will continue the editing session.
1.15 -pc
Suppresses Sedt's automatic recognition
of the system and makes Sedt assume that
it is running on an IBM PC with the PC or
XT keyboard. Use this when the
recognition code fails to recognize the
system properly.
1.16 -r
When you supply the -r qualifier all
files written to disk will have the last
line terminated with an ASCII CR
character. Use this when you are writing
or editing a file for an application that
requires this.
1.17 -ro
Set the buffer that the file is loaded
into in read only mode.
1.18 -s<Size>
Set the maximum amount of buffer space to
<Size> megabytes. The buffer space is
used to contain files being edited,
delete and paste buffers plus key
definitions.
1.19 -t<Type>
Under UNIX defines the terminal type
(prefix for key definition files).
Overrides using the contents of the term
environment variable.
1.20 -v
On IBM PCs and compatibles Sedt will
write directly to video RAM. The result
is a faster display than when the video
firmware calls are used. It may,
however, be incompatible with some video
adaptors. The -v argument forces Sedt to
use BIOS calls for all screen output.
1.21 -wi
Use the window defined by the upper left
hand corner with coordinates XX,YY (0
based) and dimensions HH,WW.
1.22 -wps
Use the WPS layout with physical mapping
to the LK250 keyboard. This switch is
not applicable to VMS.
1.23 -y<Style>
Use the argument as the editing style.
<Style> is used as the extention to key
definition and help files.

Sedt Version 4.2 (290)
2 Sedt's Data Files
For Sedt to function properly it needs a number of data
files. To help organize the files Sedt uses the concept of
libraries where the operating system supports such a facility.
The files used by Sedt are:
An optional configuration file that sedt uses to
set various options. The name of the
configuration file is always SEDT.CNF.
A keyboard map file that determines key to
function mapping.
A function definition file that defines all
predefined functions.
A Help file that can displayed during an editing
session to assist the user in remembering the
programming of the keyboard.
A file containing a graphical display of the
keyboard commands.
A default ruler file that is used to set the
ruler at initialization time.
A set of optional ruler files that can be loaded
or saved during an editing session.
An optional command file that is executed during
Sedt initialization for customization of the
editing interface.
On MS-DOS, OS/2, ATARI ST, and UNIX the data files are
located through a combination of the default directory, and the
environment variables SEDT, SEDTP, and PATH. Key map, function
definition and help files are looked for in the following order:
default directory, the directory that SEDTP points to, the
directory SEDT points to and finally in all directories pointed
by PATH. Ruler files, SEDTCOM.TXT, SEDT.REM, user supplied
initialization files are looked for in the order: default
directory, the directory SEDTP points to, the directory SEDT
points to and finally in all directories pointed to by PATH.
SEDT and SEDTP must be defined as a single directory as in SET
SEDT=C:\SEDT\. This scheme allow a lot of flexibility in
organizing Sedt's files. On single user systems the most
efficient is to define SEDT only. On multiuser systems or
networks SEDT can be set up to point at a shared, read only
directory and SEDTP at a private writable directory that is
different for every user. The easiest, but least efficient is to
install Sedt in a directory that is included in PATH.
The names of the files under MS-DOS, OS/2, ATARI ST, and
UNIX depend on the configuration. This facilitates using SEDT
from a shared server directory with different PC models.
The configuration file is always named SEDT.CNF.
The function definition file names are:
FUNDEF.yyy
Key mapping files are:
For VMS:
VAX/VMS VT100 VT100M.yyy
VAX/VMS VT200 VT200M.yyy

SCO XENIX console ansi.hlp
Where xxx is DOS for MS/DOS, WIN for Microsoft
Windows, OS2 for OS/2 and TOS for ATARI TOS and
GEM. yyy is EDT for EDT style mapping and WPS
for WPS style mapping.
The initialization file is named SEDTCOM.TXT and must be
located in the directory pointed to by the environment variable
SEDT.
On the ATARI ST under ATARI GEM all files must be in the
current directory.
On the ATARI ST under the Mark Williams C shell the
library for all data files used by Sedt is defined by the
environment variable SEDT. The contents of the environment
variable has the name of the data file appended to it to locate
the data file. If no environment variable is defined the files
must be found in the default directory. To set up the
environment use the SET command. SETENV SEDT=C:\SEDT\ specifies
that the files are found in the directory SEDT on drive C.
The names are:
Key mapping file: STTOSM.yyy
Key definition file: FUNDEF.yyy
Help file: HELP.yyy
Keyboard display file: STTOSH.yyy
Initialization file: SEDTCOM.TXT
Where yyy is EDT for EDT style mapping and WPS for WPS
style mapping.
The names of the ruler files are RULERn.TXT where n is a
digit from 0 to 9. RULER0.TXT is the default ruler file. The
initialization command file is named SEDTCOM.TXT.
2.1 Configuration File
The configuration file, SEDT.CNF, is an ASCII data file
containing one-line commands. Valid commands are:
2.1.1 AUTOSAVE=ON (Default)
After any change to a buffer Sedt will
count the keystrokes made while editing
the buffer. After 180 keystrokes a
warning will be displayed on the bottom
line. If the File has not been saved
after 200 keystrokes, Sedt saves it
automatically in a file in the same
directory as the file being edited, but
with the extension .AUS. The autosaved
version is automatically deleted when the
file is properly saved. If an autosaved
file is found when a file is loaded you
will be asked whether you want to load
the autosave instead. If you provide the
wrong answer to this question reload the
file.
AUTOSAVE=n,m
Will autosave after n keystrokes and
display the warning m keystrokes before
the autosave is due.
AUTOSAVE=OFF
Autosaving is disabled.
2.1.2 BACKUPFILE=ON (Default)
Causes Sedt to ensure that a backup
version of all files are kept.
BACKUPFILE=OFF
Causes Sedt to not create backup versions
of saved files.
2.1.3 BUFFERING=EMS (default)
On MS-DOS files being edited will be
buffered in EMS memory before overflowing
to free DOS memory and disk.
BUFFERING=NOEMS
EMS memory will not be used for buffering
of files.
BUFFERING=FREE (default)
On MS-DOS files being edited will be
buffered in free DOS memory before
overflowing to disk. You may not be able
to spawn to DOS when editing large files
when this option is set.
BUFFERING=NOFREE
Free DOS memory will not be used for
buffering of files. This preserves the
ability to spawn out of Sedt, but may
impact performance.
2.1.4 COLUMN=DISPLAYED (Default, except VMS and ULTRIX)
Enables continuous display of the current
cursor column on the banner line. This
is the default on all versions other than
VMS and ULTRIX. Enabling this option on
VMS and ULTRIX may have a significant
impact on performance across a network.
COLUMN=OFF (Default for VMS and ULTRIX)
Disables continuous display of the
current cursor column on the banner line.
This is the default on VMS and ULTRIX.
2.1.5 CONTEXT=SAVED
Save the editing context when a file is
saved. The context, containing the
current position, all marks and the
current ruler are saved in a file with
the same file name and the extension
.CTX. When Sedt edits a file, and this
option is set, it will look for the file
.CTX and restore the context. The result
is that when a file is edited again the
cursor and marks from the previous edit
session will be restored.
If you have two files in the same
directory with identical filenames, they
will default to the same .CTX file and
the .CTX file may be overwritten by the
.CTX file for the other file. To
safeguard against loading the wrong file
Sedt will verify that a file and it's
corresponding .CTX file match. If a
mismatch is found the message "Context
file does not match input file" will be
issued.
CONTEXT=FORGOTTEN (Default)

Sedt Version 4.2 (290)
3 Initialization
The initialization sequence for Sedt will go through the
following steps:
First the configuration file SEDT.CNF in Sedt's
library is read and Sedt is configured as described in
the file.
Then a default ruler file is read from Sedt's
library. The name of the default ruler file is
RULER0.TXT.
On DOS, OS/2, Microsoft Windows and ATARI ST a key
mapping file is read next. This file translates keyboard
scan codes into function key codes. The file names are:
System Keyboard File
Rainbow LK201 RBxxxM?.yyy
IBM PC IBM PCxxxM?.yyy
IBM PC/XT IBM PCxxxM?.yyy
IBM PC/AT IBM ATxxxM?.yyy
IBM CONVERTIBLE IBM CVxxxM?.yyy
PS/2 IBM NPxxxM?.yyy
ANY IBM PC ENHANCED NPxxxM?.yyy
ANY IBM PC LK250 LKxxxM?.yyy
TANDY 1400 LT TANDY TCxxxM?.yyy
Compaq SLT Compact SLTxxxM?.yyy
ATARI ST STxxxM?.yyy
Where yyy is EDT for EDT style mapping and WPS
for WPS style mapping.
Next, the key definition file is read from Sedt's
library. The name of the key definition file depends on
the system that Sedt is run on:
System Keyboard File
MS/DOS KEYDEF.yyy
Microsoft Windows KEYDEF.yyy
OS/2 KEYDEF.yyy
ATARI ST KEYDEF.yyy
VAX VT100 VT100M.yyy
VAX VT200 VT200M.yyy
UNIX VT100 vt100.key
UNIX VT200 vt200.key
SCO XENIX console ansi.key
Where yyy is EDT for EDT style mapping and WPS
for WPS style mapping.
Next Sedt will position the cursor at the line
number requested in the command line if a -<line number>
qualifier was supplied.
Then Sedt will look in Sedt's library for a file
containing initialization commands for the editor. If a
file is found it's contents will be interpreted as
internal Sedt commands. The name of the file is
SEDTCOM.TXT.
Finally, Sedt will look for a checkpoint file in
the same directory as the file you are editing and with
the same name except for the extension .AUS. If one is
found, Sedt will ask you whether you want to load the
checkpoint file instead.

Sedt Version 4.2 (290)
4 Using the MS-DOS version of Sedt
The MS-DOS version of Sedt follows the generic
description given in the previous two chapters, but adds support
for a mouse if a Microsoft mouse compatible driver is installed.
4.1 Support of the Microsoft mouse driver
If Sedt recognizes the presence of a mouse it
will display a block cursor within the window. The
cursor will move around the window if you move the mouse.
Clicking the left mouse button will move the text
cursor to the position you clicked at. Any active select
region is canceled. If the mouse is dragged with the
left mouse button held down the cursor will move with the
mouse and the region between the point where the cursor
was originally pressed and the current cursor will be
selected.
Clicking the right mouse button will select the
text between the mouse cursor and the text cursor.

Sedt Version 4.2 (290)
5 Using the Microsoft Windows version of Sedt
WSEDT.EXE is special version of Sedt running as a class A
application under Microsoft Windows. In addition to the
functionality described elsewhere in this manual it offers mouse
control, menus, sizable and movable windows and an interface to
the Windows clipboard.
Because of the multitasking environment Sedt cannot take
full control of the keyboard or even assume that the keyboard
state is known. Therefore Sedt does not support the Num Lock and
Scroll Lock keys as normal editing keys.
5.1 Window Control
When you run Sedt is displays a normal MS window
with a menu bar, a size box and a vertical scroll bar.
All of these controls work exactly as with any other
Windows application. When the window is resized you will
notice that Sedt adapts to the new windows size so that
horizontal shifting and vertical scrolling work exactly
the same.
The initial window will display buffer 0. As you
open other buffers, they will be displayed in new
windows. You can display the contents of several buffers
at a time. As with the stand alone version, you can have
four concurrently open windows. These are displayed in
independent MS-Windows windows that can be moved and
controlled independently.
5.2 Mouse Control
The mouse cursor is an I-bar text cursor when it
moves within the file display. Outside the file display
it changes into an arrow pointer.
Apart from the normal mouse controls of the
windows and menus, you can also use the mouse to position
the text cursor within the visible window and to select a
region of text.
To position the cursor, place the mouse pointer
at the character position you want the cursor at, and
click the left button. The cursor will move to the
selected position unless the position is further to the
right than the last character on the line, or past the
end of the buffer. If the selected position is further
to the right than the end of the line the cursor will be
placed over the last character on the line. If it is
past the end of the buffer you will get an error message.
If you select a point on the first or last line
of the buffer the window will scroll one line.
To select a region of text you can use the mouse
in two different ways. If you drag the cursor after
clicking it the region from the initially selected
cursor position to the point where you release the mouse
button will be the selected region. If you accidentally
select a region by dragging, you can cancel the select
region by moving the mouse cursor to the block cursor and
clicking the right mouse button. Alternately, a region
can be selected by moving the mouse cursor to the end of
the select region and clicking the right mouse button.
In either case the selected region will change to reverse
video.
5.3 Menu Control
The menu bar will display five titles: File,
Window, Edit, Ruler and Help. To select any of these
move the mouse cursor to the title and a drop down menu
will appear. To select an item move the mouse cursor to
the item and click the left mouse button. A drop down
menu will appear as long as you hold down the left mouse
button. To select a menu item drag the cursor till the
item you want is highlighted and release the mouse
button.
5.4.1 File
This menu is used to control the file being
edited in the window.
5.3.1.1 New
Clears the current window. If the window
contains an unsaved file a dialog box
will appear and you will be asked for
confirmation before the unsaved edits are
removed.
5.3.1.2 Open..
Displays a file selector dialog box.
The file you select in the box is loaded
into the current buffer.
5.3.1.2 Save
Saves the file in the current buffer onto
the file displayed after "File:" in the
top line of the window.
5.3.1.3 Save as..
Displays a file selector dialog box. The
contents of the buffer are saved onto the
file you select. The file name displayed
after "File:" in the top line of the
window is also changed to the name of the
file you selected.
5.3.1.4 Insert..
Displays a file selector dialog box. The
file selected is included in the buffer
at the current cursor position.
5.3.1.5 Quit
Closes the current window. If there are
unchanged buffers you will be asked for
confirmation before the session is
terminated. Sedt will terminate when the
last window is closed.
5.3.2 Window
The window menu allows you to switch between
buffers and to clear the contents of a window.
5.3.2.1 Untitled
Unused
<File name>
Makes the window containing the indicated
buffer the currently selected window.
The menu item shows the current state of
the window. Untitled is an open window
with no file associated with it. <File
name> is the name of the file being
edited, and Unused is a closed window.
5.3.2.2 Switch
Selects the window you were in when you
last selected a new window.
5.3.3 Edit
The edit menu allows you to control the select
region.
5.3.3.1 Clear
Clears the select region. This is useful
when you have accidentally activated a
select region by moving the mouse while
holding the button down.
5.3.3.2 Cut
Cuts the selected region and saves it in
the paste buffer.
5.3.3.3 Paste
Inserts the contents of the paste buffer
at the text cursor position.
5.3.4 Ruler

Sedt Version 4.2 (290)
Sedt hints and tricks
EDT Mode
6.1 Using Sedt for programming
A number of features in Sedt are designed to make
programming easier. This section describes these
features and how best to take advantage of them.
Autoindentation
By setting the ruler for automatic indentation
(type A anywhere on the ruler when in ruler
definition mode) Sedt is set up to indent
automatically to the level of the line you just
terminated after you type a <Return>. This
facility makes it easy to write programs in a
structured fashion with the indentation level
proportional to the level of nesting.
Matching bracketing characters
When programming, especially in C and LISP,
nesting is often hard to get right. Sedt will
locate a matching bracket (', ", <, >, [, ], {,
}, (, or )) if you position the cursor over the
character and type <Gold> <F19>. This facility
can also be used to move over sections of the
program.
Compiling from within Sedt
By defining a key to save the current file and
spawn a compiler you can compile a program
without leaving Sedt. If the compiler generates
a listing of error messages, you can define the
key to also load the listing in another buffer.
Defining templates
By using the lean key feature, you can define a
series of keys in such a way that they insert
templates for key language constructs.
6.2 Using Sedt for text and documents
Formatting
Use word wrap and right margin, either ragged or
justified to format paragraphs as you type. If
you make changes to an already formatted
paragraph, reformat the paragraph with <Gold> J.
It is a good idea to have multiple stored rulers
for different levels of indentation.
Post processing
Sedt is not a word processor and does not support
many features such as bolding and underlining.
There are, however, a number of post processors
that together with Sedt will provide a more than
acceptable word processing environment. Define a
key to save the file, post process it and then
print the final output.
Spelling checkers
Sedt works very well with resident spelling
checkers such as Turbo Lightning on PC/DOS and
Thunder on the ATARI ST. With a spelling checker
and thesaurus, you have a superb environment for
producing documents.
6.3 Repetitive tasks
A number of tricks can be used to facilitate
tasks that require repetition of a task many times. The
techniques are based on the ability to dynamically change
key definitions. Usually a combination of the techniques
described lead to the optimal effort reduction.
Using learned key sequences
The standard technique for reexecuting a key
sequence is to type <Gold> <F17> at the start of
the sequence and terminate the sequence with ^B.
The sequence can then be replayed once by typing
^B and many times by typing <Gold> <Number>
^B. <Number> is the number of times you want to
repeat the sequence and must be typed on the
regular typewriter keyboard.
More advanced use of learned key sequences
You can learn keystrokes into other keys than ^B
by starting the process by typing <Gold> <F18>
and then typing the key you want to learn into
when prompted. To exit learning mode type the
key you are learning into. The learned keystroke
sequence can be replayed by typing the same key
again.
Redefining complex keystroke sequences
A very simple technique is to redefine a command
that is tied to a complex key sequence to a
single keystroke. You can very easily redefine a
gold key sequence to a single keystroke by typing
^K, then the single key you will tie the command
to, <Return>, the old keystroke sequence, and
finally <Return>.
Using commands not tied to keys by default
The default key definitions only use a subset of
Sedt's capabilities. You can often simplify
tasks by taking advantage of the more extensive
capabilities of the basic command set.
Turning screen updates off
When a repetitive sequence generates extensive
screen updates it can be simplified by taking
advantage of the ability to turn screen updates
off.
6.4 Creating Menus
Often, you would like to taylor Sedt to more complex
editing environments. The command structure offers many
opportunities to do this. One way, which is not obvious,
is described here.
If you would like to take an action determined by a
choice by the user, you can do so by tying a command
sequence like the following to a key:
^E(:FX|%e?"Enter document type L)etter, P)rogram, M)emo :"tpe.sed|)(:OM"Invalid menu selection").
When the key is pressed the commands in a file stored in
Sedt's library area will be executed. If L is typed the
file Ltpe.sed is selected. P and M will execute Ptpe.sed
and Mtpe.sed.
6.5 Using different initialization files for different file types
You can make Sedt initialize itself automatically for
different file types by creating a SEDTCOM.TXT file with
^E(:FX\%E%T.INI\)(:OM"No initialization file").
For any file type you edit Sedt will look for a file with
the name <type>.INI in Sedt's library area. If none is
found, a message will be issued.
6.6 Using linked files under UNIX
If you use linked files under UNIX you will find that the
links get broken if BACKUPFILE=ON, which is the default.
This is caused by Sedt using file links to create backup
files. You can prevent this problem by putting
BACKUPFILE=OFF in SEDT.CNF. Unfortunately, you will not
have the added security of backup files, but you will be
able to edit linked files without breaking the links.
6.7 Changing the keyboard macros
It is often desirable to change Sedt's keyboard macros or
the keys they are assigned to. A very common example is
laptop users who want to use EDT emulation. You will
need to change up to 3 files:
The macro file: FUNDEF.???
The key mapping file: ?????M.???
The key layout help file: ?????H.???
The key macro and mapping files are binary files created
from files named FUNDEFI.??? and ?????MI.??? with
MAPKEY. See the documentation on MAPKEY elsewhere in
this document.
The macro file contains all predefined macros. If you
want to change how a macro works, find it in FUNDEFI.???,
edit it and recompile with MAPKEY.
The assigment of macros to actual keys is done by the key
mapping file. This has several sections. The first
assigns keystrokes to a number of standard keys. MAPKEY
can automate this section with the MAPKEY CREATE command.
This is particularly useful when you use EDT mapping,
where all the keys are defined as standard keys. Where a
key generates a multicharacter sequence MAPKEY CREATE can
save you significant work. This is particularly useful
when porting Sedt to terminals under VMS and UNIX.

Sedt Version 4.2 (290)
7 Customizing Keyboards
Keyboard commands are defined by two files. The keyboard
map file defines how keyboard input is mapped into a set of
predefined functions. The predefined functions are defined in a
function definition file. Both of these files are in a binary
format and must be created with a utility program called MAPKEY.
The keyboard map files are unique for every keyboard,
wheras there is only one function definition file for each
editing style (EDT or WPS).
To customize Sedt for a new keyboard you can normally
leave the function definition file and the MAPS section of the
key definition file unchanged. What remains is to change the
KEYS and COMBINATIONS sections in the key mapping file. Take
some time to compare different key mapping files. This will give
you and idea of the work to be done. You will be surprised at
how similar they are.
7.1 Function definition file
Before building a keyboard map file you need to build a
function definition file, or print the contents of the one you
want to map the keyboard to. The Sedt distribution contains
FUNDEF.INP, which is the ASCII file used to create the EDT style
function definition file FUNDEF.EDT.
The format of this file is as follows:
Comment lines have a ; as the very first
character of the line.
Function definitions are two lines with NO
comments allowed between the two.
The first line has the format:
<No> <Definition>
Where <No> is the number that you have assigned
to the function being defined, and <Definition> is the
function definition. The contents of a function
definition is described in the next section of this
manual.
The second line is the help text assigned to the
function and is free format text.
7.2 Keyboard map file
Keyboard map files can either be created interactively
using the MAPKEY program's CREATE command, or by using a text
editor. MAPKEY CREATE only implements a subset on the
capabilites the other method implements, but requires very little
knowledge of keyboards and the codes they send.
MAPKEY CREATE FOO.BAR
creates an ASCII file names FOO.BAR with valid input to
the MAPKEY COMPILE KEYS function. It will first prompt you for a
terminator key which should be chosen carefully since it cannot
be one of the keys you want to program. The spacebar is a
potential good choice. MAPKEY will then issue prompts for 52
predefined keys. In response to each key you should type the
key, or a combination of keys that you want to use instead of the
key, and terminate the input woth the terminator key MAPKEY
prompted you for. Typing the terminator only in response to a
prompt will skip that particular key. At the end of the prompts
MAPKEY will write the file you selected. You need to further
edit this file to include the appropriate MAPS section, but in
most cases you will be able to copy this section from an already
existing file.
MAPKEY EDIT FOO.BAR BAR.DAT
will read an ASCII mapfile, FOO.BAR, add new entries to
it interactively and save the resultant in an ASCII mapfile,
BAR.DAT.
To create a keyboard map file with an editor you first
need to know the characters that each key sends. This is done
with MAPKEY using the command
MAPKEY CHAR
and
MAPKEY SCAN
Only use MAPKEY SCAN if MAPKEY CHAR does not print a
value when the key is pressed, or if the values printed are
ambiguous.
To exit from MAPKEY type an Escape character under DOS,
OS/2, or ATARI ST and a control Z on all other systems.
You may find that some keys that you want to use
differently send identical codes, and other keys transmit no
codes to the application. Under DOS and OS/2 you have the
ability to bypass the keyboard firmware. The codes transmitted
to the firmware can be explored with MAPKEY typing
MAPKEY SCAN
You also exit from this mode by typing Escape.
MAPKEY is not supported under Windows. To get access to
the codes, include a line with DEBUG=ON in SEDT.CNF and run the
Windows version of Sedt. Whenever a key is pressed the scan and
windows code for the key will be inserted in a file named DUMP in
the directory you run WSEDT from.
Once you know the codes transmitted by all keys you are
ready to start building the ASCII file that MAPKEY uses to build
the keyboard map file.
Any line starting with a semicolon (;) is a comment line.
Any line starting with an ampersand (@) includes the
contents of a file named in the rest of the line.
The start of the keyboard file contains optional setup
and reset strings for the system or terminal.
The setup string for the terminal is defined by a line
containing the word INITIALIZE followed by a line
containing the initialization string.
The reset string for the terminal is defined by a line
containingthe word RESET followed by a line
containing the reset string.
The rest of input file has four optional sections:
1: Codes that the firmware needs to be bypassed
with.
2: Assignment of single keystroke codes to key
numbers.
3: Assignment of multiple keystroke sequences to
key numbers.
4: Mapping of keystrokes to function numbers.
Section 1 contains a the keyword SPECIAL followed by a
single line for each code that the firmware needs
to be bypassed for in the firmat:
S<Scancode> <Character>
E<Scancode> <Character>
or
W<Windows code> <Character>
<Scancode> is the scancode value that MAPKEY
printed and <Character> is the ASCII character
that you have decided to assign to the key.
(ASCII character values are normally assigned by
the firmware). E is used where MAPKEY informed
you that the scancode is extended and S is used
for normal scancodes.
For OS/2 E<Scancode> <Character> has a special
meaning: Special handling by OS/2 of the
scancode/character combination will be disabled.
This makes it possible to treat ^C among other
characters as normal input to Sedt.
<Windows code> is a keycode assigned by Microsoft
Windows. When referring to the key later in the
key definition file use S<Windows code>. These
codes are only partially documented in the
Windows developer's kit. The following is the
best listing of Windows keycodes that I can
supply.

You should only enter values into this section if
MAPKEY CHAR either doesn't return any value for a
key, or if the keystroke generates an ambiguous
code. Failure to do so will result in problems
accessing TSR programs from DOS and also creates
unnecessary overhead.
Section 2 consists of a line containing the text KEYS
followed by a line for each key number assignment
you want to make.
Each line has the format:
S<Scancode> <Character> <Value>
E<Scancode> <Character> <Value>
A<Character> <Value>
The S format is used for normal scancodes, E for
enhanced scancodes, and A where you want to
assign a character to a key value regardless the
scancode.
Where <Scancode> and <Character> are values given
to you by MAPKEY or assigned in section 1 of this
file, and <Value> is the key value you have
assigned to the key. Sedt uses some key values
internally, and you should use the following
meanings for the values given in the following
table:

Any other key numbers are freely assignable and
carry no special meaning.
Section 3 consists of a line containing the text
COMBINATIONS followed by a number of lines of the
following formats
<Level> E<Scancode> <Character>
<Level> S<Scancode> <Character>
<Level> A<Character>
<Level> K<Key>
<Level> E<Scancode> <Character> <Key #> <Help text>
<Level> S<Scancode> <Character> <Key #> <Help text>
<Level> A<Character> <Key #> <Help text>
<Level> K<Key> <Key #> <Help text>
<Level> designates the number of the keystroke in
the sequence.
E<Scancode> <Character> is an extended
scancode/character combination.
S<Scancode> <Character> is a normal
scancode/character combination.
A<Character> is any ASCII character.
K<Key> is a key number assigned in the previous
section.
For the final character in a sequence <Key #> is
the key nymber you assign to the sequence.
<Help Text> is the help text to be used in
interactive help, or a prompts given on the
bottom line of the screen. Which it is is
determined by the first character, which is not
included in the text. A single quote labels the
text as a prompt and a double quote as a help
text. If neither is sees the text is assumed to
be a help text.
To describe a sequence consisting of ^A^B which
you want to assign as key number 99 and give the
help text ^A^B to include:
1 A1
2 A2 99 ^A^B
To describe two sequences consisting of ^A^B^C
and ^A^B^D and assign them to key bumbers 99 and
100 include:
1 A1
2 A2
3 A3 99 ^A^B^C
4 A4 100 ^A^B^D
Two sequences consisting of ^A^B^C^D and ^A^B^D^E
would be described as:
1 A1
2 A2
3 A3
4 A4 99 ^A^B^C^D
3 A4
4 A5 100 ^A^B^D^E
As you can see, you are building a tree structure
where common root sequences are only included
once. You must follow this scheme.
Section 4 consists of a line containing the text MAPS and
a number of lines in the following formats:
<Number> S<Scancode> <Character> <Function> <Help Text>
<Number> E<Scancode> <Character> <Function> <Help Text>
<Number> A<Character> <Function> <Help Text>
<Number> K<Key> <Function> <Help Text>
<Number> G S<Scancode> <Character> <Function> <Help Text>
<Number> G E<Scancode> <Character> <Function> <Help Text>
<Number> G A<Character> <Function> <Help Text>
<Number> G K<Key> <Function> <Help Text>
<Number> is the index into the table. This index
is used by several commands that reference keys.
It is suggested that you number all entries
sequentially starting with 0.
G just after <Number> means that this mapping
value applies when the <Gold> key was typed
immediatly before the key generating the entry.
<Scancode>, <Character>, and <Key> define the
key.
<Function> specifies the function the key is to
assigned to. A function number of 0 or the
letter G means that the key being defined is a
<Gold> key.
<Help Text> is the help text assigned to the key
or key sequence.
Sedt searches all of these tables sequentially
from the start to the finish. You must take care to
ensure that an A<Character> entry is not placed before a
S<Scancode> <Character> or E<Scancode> <Character> with
the same character value. You must also place a K<Key>
entry before any entry that might produce a match for the
same character. It is helpful to start with all K
entries, followed by all E and S entries, finally
followed by all A entries.
7.3 MAPKEY Program
The MAPKEY program is used to maintain keyboard map and
function definition files.
MAPKEY Commands:
MAPKEY SCAN
Prints scancodes for keys pressed. This command
bypasses the firmware and prints scancodes for
all keys, even those that normally are trapped by
the firmware. To terminate MAPKEY type Esc.
MAPKEY CHAR
Prints scancode and character values for keys
pressed. This command shows the keypresses after
they are processed by the firmware. To terminate
MAPKEY type Esc.
MAPKEY CREATE <ASCII file>
Created a valid input file to MAPKEY COMPILE KEYS
by prompting you to type the appropriate keys.
MAPKEY COMPILE KEYS <ASCII file> <Binary file>
Comverts an ASCII keyboard map file into the
binary format required by Sedt.
MAPKEY DUMP KEYS <Binary file> <ASCII file>
Converts a binary keyboard map file into an
editable ASCII format suitable for input to the
COMPILE KEYS command.
MAPKEY TEST <ASCII file>
Reads a file suitable for input to the COMPILE
KEYS command and displays how Sedt will interpret
keystrokes. To terminate MAPKEY type Esc.
MAPKEY COMPILE FUNCTIONS <ASCII file> <Binary file>
Converts an ASCII function definition file into
the binary format expected by Sedt.
MAPKEY DUMP FUNCTIONS <Binary file> <ASCII file>
Converts a function definition file in the binary
format required by Sedt into an editable ASCII
format suitable for input to the COMPILE
FUNCTIONS command.
7.4 Porting Sedt to a new keyboard
To port Sedt to a new keyboard chose a name which you
will use in SEDT.CNF to refer to the new keyboard. Under
UNIX you should chose the value of the TERM environment
variable.
Next, run MAPKEY CREATE to record the character codes
sent by the terminal.
The next step is to copy the MAPS section of an already
existing keyboard file that implements the editing style
you prefer into the MAPS section of the file you created
with MAPKEY CREATE.
The last step is to use MAPKEY COMPILE KEYS to create a
binary map file.

8 Help File
The help file is designed to create a tree structured
menu of help screens. The first few characters of every line are
used to drive the menu structure.
Space Lines starting with space are displayed on the
screen and constitute the normal output, either
help text or menu screens.
Character Lines starting with any other character defines
the menu structure. The first character is the
first level selection. Lines starting with just
this character come just before the first line of
output for this level. Lines with more than one
character define inner menus.
Inside the help text a number of tokens are allowed.
Each token starts with a % character. A special token, %%,
leaves a single % character in the help text.
%A<Number> Inserts the help text for all keys that map to
the given function number. Multiple help strings
are separated by commas and spaces.
%F<Number> Inserts the help text for the first key found
that points to the function number given.
%T<Number> Inserts the help text for the given function
number.
%C<Number> Advances the cursor to the given column.
%K Inserts the contents of the keyboard map file.

Reference Manual
9.1 Interpreting Keyboard Input
Whenever a control character, a function key or a key
preceded by <Gold> is typed Sedt will translate the keystroke
into a series of internal commands. The mapping of keys to
internal commands is defined by a key definition file and can be
modified during the editing session.
This chapter describes the syntax for internal commands
and describes the sequence of events between typing a key and the
effect of the command being displayed on the terminal.
Sedt understands a large variety of commands and command
combinations that have not been tied to any keys. To take full
advantage of Sedt's power you will need to understand the
internal command structure.
9.2 Translating Keystrokes
When a key is typed the commands tied to the key will be
written to an internal buffer. If the command string is not
terminated by a period the command sequence will be stored and a
new key will be read. This continues until a key with a
definition terminated by a period is typed. This facilitates the
use of multiple keystrokes to input a command sequence.
The next step is to scan the command string for tokens
and prompts. Tokens are replaced by the value of the token at
the time of scanning and prompts will be displayed and then
replaced by the response to the prompts. The recognized tokens
and prompt strings are:
? will cause SEDT to expect the following syntax:
?<delimiter><string><delimiter>
where <delimiter> is any ASCII character. SEDT will
display <string> on the bottom line of the display and
then accept input from the keyboard.
! will cause SEDT to expect the following syntax:
!<delimiter><string><delimiter>
where <delimiter> is any ASCII character. SEDT will
display <string> on the bottom line of the display and
wait for a key or <Gold> followed by a key to be struck.
A unique ASCII representation for the key will be
inserted in the command string instead of the above
construct.
% must be followed by one of the following characters:
%, #, B, C, D, E, F, H, L, N, P, T, or W.
%% is replaced by a single %.
%#<Letter> is replaced by the current value of
the counters controlled by :CNS, :CNI and :CNP.
<Letter> must be in the range A to Z.
%A is only supported on VMS and MS-DOS, OS/2,
ATARI ST, and UNIX. On VMS it will be replaced
by the string Sedt$Dir:, and on MS-DOS, OS/2,
ATARI ST, and UNIX by the value of the SEDTP
environment variable.
%B is only supported on VMS and inserts the next
unseen broadcast message.
%C is replaced by the current character position.
%D is replaced by the device and directory
specification of the output file of the current
buffer.
%E is only supported on VMS and MS-DOS, OS/2,
ATARI ST, and UNIX. On VMS it will be replaced
by the string Sedt$Library:, and on MS-DOS, OS/2,
ATARI ST, and UNIX by the value of the SEDT
environment variable.
%F is replaced by the name of the output file of
the current buffer being edited.
%HNNN is replaced by the help text for the
function pointed to by MAP entry NNN. The
command sequence :OM/!"Key: "/. will print the
help text for the key pressed in response to the
prompt.
%L is replaced by the current line number.
%N is replaced by the name of the output file of
the current buffer being edited, up to, but not
including, the first period.
%P is replaced by the contents of the paste
buffer
%T is replaced by the file type, including the
leading period, of the output file of the current
buffer.
%W is replaced by the current cursor column.
9.3 Command Syntax
Once the command string has been preprocessed it is
interpreted as a series of commands. This chapter describes all
SEDT commands. For some examples of how keys are programmed
study the keyboard definition file supplied with Sedt.
If an error occurs during execution of a command string
all commands following the one that the error occurred in will be
skipped. Also, if the command was in a series of commands
enclosed in parentheses preceded by a count the parentheses are
exited and further iterations skipped.
SEDT commands may be grouped by placing them in
parentheses. A count in front of a group of commands in
parentheses causes the group to be repeated the number of times
given in the count.
It is also possible to execute commands conditionally.
^C(<Commands>) causes <Commands> to be executed only if
the current buffer contains unsaved changes.
^C(<Commands1>|<Commands2>) causes <Commands1> to be
executed if the buffer contains unsaved changes and
<Commands2> to executed if the buffer is unchanged.
^E(<Commands1>)(<Commands2>) causes <Commands1> to be
executed. If any error occurs during the execution the
rest of <Commands1> will be skipped and <Commands2> will
be executed. <Commands2> string is ignored if no error
occurs.
^E(<Commands1>)(<Commands2>|<Commands3>) will execute
<Commands1>. If an error occurs the rest of <Commands1>
will be skipped and then <Commands2> will be executed,
otherwise <Commands3> is executed after completion of
<Commands1>.
^LB(<Commands1>) causes <Commands1> to be executed if the
cursor is at the beginning of a line.
^LB(<Commands1>|<Commands2>) causes <Commands1> to be
executed if the cursor is at the beginning of a line,
otherwise <Commands2> is executed.
^LE(<Commands1>) causes <Commands1> to be executed if the
cursor is at the end of a line.
^LE(<Commands1>|<Commands2>) causes <Commands1> to be
executed if the cursor is at the end of a line, otherwise
<Commands2> is executed.
^S(<Commands>) causes <Commands> to be executed only if
there is a select region active.
^S(<Commands1>|<Commands2>) causes <Commands1> to be
executed if a select region is active. If no select
region is active <Commands2> will be executed>.
^Z(<Commands>) causes <Commands> to be executed if the
current buffer is empty and not assigned to a file.
^Z(<Commands1>|<Commands2>) causes <Commands1> to be
executed if the current buffer is empty and not assigned
to a file, otherwise <Commands2> is executed.
To save a flag and have it restored after a command
sequence you bracket the command sequence and precede it with one
of the following commands:
^TB(<commands>) Saves the block/line mode flag and
restores it after <commands> have been executed.
^TD(<commands>) Saves the direction flag and restores it
after <commands> have been executed.
^TF(<commands>) Saves the cursor behavior toggle and
restores it after <commands> have been executed.
^TI(<commands>) Saves the replace/insert mode flag and
restores it after <commands> have been executed.
^TT(<commands>) Saves the the tab insert/expand flag and
restores it after <commands> have been executed.
^TU(<commands>) Saves the the case sensitivity flag and
restores it after <commands> have been executed.
^TX(<commands>) Saves the the state of inserting
function definitions in prompts and restores it
after <commands> have been executed.
The following construct will execute commands
conditionally depending on the value of a toggle:
^IB(<commands>) Executes <commands> if cut operates in
line mode.
^IB(<commands1>|<commands2>) Executes <commands1> if cut
operates in line mode and <commands2> if cut
operates in block mode.
^ID(<commands>) Executes <commands> if the default
direction is forward.
^ID(<commands1>|<commands2>) Executes <commands1> if the
default direction is forward and <commands2> if
the default direction is reverse.
^IF(<commands>) Executes <commands> if the cursor
is alowed to move freely.
^IF(<commands1>|<commands2>) Executes <commands1> if the
cursor is allowed to move freely and <commands2>
if it is restricted to the length of lines in the
file.
^II(<commands>) Executes <commands> if characters are
inserted when typed.
^II(<commands1>|<commands2>) Executes <commands1> if
typed characters are inserted and <commands2> if
typed characters replace existing text.
^IT(<commands>) Executes <commands> if typed tab
characters are expanded to spaces.
^IT(<commands1>|<commands2>) Executes <commands1> if
typed tab characters are expanded to spaces and
<commands2> if types tab characters are inserted.
^IU(<commands>) Executes <commands> if searches are case
insensitive.
^IU(<commands1>|<commands2>) Executes <commands1> if
searches are case insensitive and <commands2> if
searches are case sensitive.
^IX(<commands>) Executes <commands> if function
definitions are inserted in responses to prompts.
^IX(<commands1>|<commands2>) Executes <commands1> if
functio definitions are inserted in responses to
prompts and <commands2> if they are not.
SEDT commands are alphanumeric strings preceded by either
the symbol @ or :. Commands preceded by @ define a cursor
position and normally move the cursor to the position the command
defines. Commands preceded by : are action commands that
perform a change on the file being edited or change the editing
environment. Some action commands must be followed by a position
command that defines the range of text that the command acts on.
All commands can be preceded by a direction indicator
and/or a count. Not all commands use the direction indicator or
count. Those that do have the direction indicator or count in
the syntactical description.
The direction indicator is one of +, -, < or >. + and >
set the current direction to be forward, toward the last
character in the buffer. - and < set the current direction to be
backward, toward the first character in the buffer. If no
direction indicator is provided the command will use the default
direction, which initially is forward but can be changed with the
commands :A and :B.
Count is either a string of decimal digits optionally
followed by a dollar sign, $, and another string of decimal
digits, or a dollar sign, $, followed by a string of decimal
digits. If no dollar sign is in the count, or it starts with a
dollar sign, it is interpreted as the decimal value defined by
the string. If the count contains a dollar sign between two
decimal strings it is interpreted at the decimal value defined by
the first string. If no count is given the command will use a
count of one. This feature allows you to program a key to have a
default count by starting the definition with $<count>; If the
user supplies a count, it will override the one after $.
$10 returns the count 10
20$30 returns the count 20
40 returns the count 40
9.4 Commands
9.4.1.1 @AC
Absolute Character
Syntax: {<Count>}@AC
Semantics: Move the cursor to the absolute character
position <Count> in the current buffer.
9.4.1.2 @AL
Absolute Line
Syntax: {<Count>}@AL
Semantics: Move the cursor to the start of absolute line
<Count> in the current buffer.
9.4.1.3 @BB
Beginning of Buffer
Syntax: @BB
Semantics: Move the cursor to the first character in the
current buffer.
9.4.1.4 @BM
Matching Bracketing Character
Syntax: @BM
Semantics: Move the cursor to the matching character if the
character under the cursor is one of: ', ", <,
>, [, ], {, }, (, or ). ' and " are searched for
in the current direction, the others in the
direction the character implies.
9.4.1.5 @EB
End of Buffer
Syntax: @EB
Semantics: Move the cursor to the end of the current buffer.
The cursor position will be right after the last
character in the buffer.
9.4.1.6 @EL
End of Line
Syntax: <Count>@EL
Semantics: Move the cursor to the next end of line in the
current direction. The end of line is the
position to the immediate right of the last
character in the line. 0+@EL is a special case
which always stays at the end of the current
line.
9.4.1.7 @ES
Other end of found text
Syntax: @ES
Semantics:
If the previous command was a search, the new
entity is the other end of the text that matched
the search. This command does not work properly
with regular expression searches.
9.4.1.8 @C
Character
Syntax: {+|-|<|>}{<Count>}@C
Semantics: Move the cursor <Count> characters in the current
direction. The end of line terminator is counted
as a character.
9.4.1.9 @F
Find
Syntax: {+|-|<|>}{<Count>}@F<Delimiter><String><Delimiter>
Semantics: If the <String> is not empty load it into an
internal buffer called the current search string.
The search for an occurrence of the current
search string in the current direction and place
the cursor over the first character in the
occurrence. The search is case insensitive.
9.4.1.10 @L
Line
Syntax: {+|-|<|>}{<Count>}@L
Semantics: Move the cursor to the <Count>'th start of line
in the current direction. The start of line is
the first character on the line, blank or
non-blank. 0-@L is a special case, which stays
at the beginning of the current line.
9.4.1.11 @M
Mark
Syntax: {<Count>}@M
Semantics: Move the cursor to the position in the file
where the cursor was when a :M command with the
same count was executed last. Valid counts are 1
through 10. An error message is displayed if an
invalid count is given or a :M command has not
previously been executed with the same count.
9.4.1.12 @N
Next
Syntax: {+|-|<|>}{<Count>}@N
Semantics: Move the cursor to the <Count>'th occurrence in
the current direction of the string last given in
an @F command. The cursor is placed over the
first character of the string. The search is
case insensitive.
9.4.1.13 @PAG
Page
Syntax: {+|-|<|>}{<Count>}@PAG
Semantics: Move the cursor to the first character after the
<Count>'th ASCII <FF> in the current direction.
If there are <Count>-1 ASCII <FF>'s in the
current direction the cursor will be placed at
the beginning of the file if the direction is
backwards or at the end of the file if the
direction is forward.
9.4.1.14 @PAR
Paragraph
Syntax: {+|-|<|>}{<Count>}@PAR
Semantics: Move the cursor to the <Count>'th start of
paragraph in the current direction. If there are
exactly <Count>-1 beginning of paragraphs the
cursor will be placed at the beginning of the
file if the direction is backward or at the end
of the file if the direction is forward. A
beginning of paragraph is a sequence of ASCII
space, tab and line feeds containing at least two
line feeds. The cursor is placed on the first
character after the string of spaces, tabs and
line feeds.
9.4.1.15 @SCR
Screen
Syntax: {+|-|<|>}{<Count>}@SCR
Semantics: Move <Count> times one less than the number of
lines in the current window lines in the current
direction.
9.4.1.16 @SEN
Sentence
Syntax: {+|-|<|>}{<Count>}@SEN
Semantics: Move to the <Count>'th start of sentence in the
current direction. A start of sentence is the
first character after a string of ASCII spaces,
tabs, line feeds, <.>, <;>, <?>, <!>, or <:>
containing exactly one line feed, <.>, <;>, <?>,
<!>, or <:> . If there are exactly <Count>-1
sentences the cursor will be placed at the start
of the file if the direction is backwards or at
the end of the file if the direction is forward.
9.4.1.17 @SR
Select Range
Syntax: @SR
Semantics: Move the cursor to the point the cursor was at
the last time a :SEL command was executed. An
error message is displayed if a :SEL command has
not been executed.
9.4.1.18 @V
Vertical
Syntax: {+|-|<|>}{<Count>}@V
Semantics: Move the cursor <Count> lines in the current
direction. SEDT attempts to position the cursor
at the same column as the cursor was at before a
series of @V commands were issued. The cursor is
never placed further to the right than one column
to the right of the last character on a line. If
the line contains ASCII tab characters or
characters that SEDT represents with
multi-character sequences it may not be able to
position at exactly the same column.
A series of these commands will attempt to keep
the cursor at the column it was at when the first
command was executed.
9.4.1.19 @W
Word
Syntax: {+|-|<|>}{<Count>}@W
Semantics: Move the cursor <Count> words in the current
direction. A word is either an alphanumeric
string containing underscores <_> or printable
ASCII characters or a single non-alphanumeric,
printable ASCII character. The cursor is
positioned over the first character in the word.
9.4.1.20 @XNM
Next Mark
Syntax: @XNM
Semantics: Move to the next marked position. The next mark
is the closest in the current direction. An
error is caused if there are no more marks in the
current direction.
9.4.1.21 @XSR
Select Range with no clear
Syntax: @XSR
Semantics: Exactly the same as @SR, but the select region is
not cleared.
9.4.2.1 :A
Advance
Syntax: :A
Semantics: Set the default direction for cursor-movement
commands to be forward toward the end of the
file.
The default direction is displayed on the mode
line of the display.
9.4.2.2 :B
Backward
Syntax: :B
Semantics: Set the default direction for cursor-movement
commands to be backward toward the start of the
file.
The default direction is displayed on the mode
line of the display.
9.4.2.3 :CB
Cursor at Bottom
Syntax: :CB
Semantics: Scrolls the current window to place the cursor
line at the next to last line in the window. Is
only available in full screen editing mode.
9.4.2.4 :CC
Change Case
Syntax: :CC<@ command>
Semantics: Switch all lower case characters to upper case
and all upper case characters to lower case from

valid codes for <Key>.
9.4.2.51 :LNL
Store keystrokes in key
Syntax: :LNL<Key>
Semantics: Store subsequent keystrokes in the programming of
the key defined by <Key> until that key is
struck. The keystrokes are executed as they are
stored. The commands :LNL and :LNE are used to
store the keystrokes required to perform a
repeated task and then perform the task without
having to repeat the keystroke sequence. See :K
for a description of valid codes for <Key>.

advance the cursor to the beginning of the new
line.
If the ruler line has automatic margin control
set the margin is set to the leftmost character
position not containing spaces and tabs in the
line the cursor was on. If the old line had only
spaces or tabs the automatic margin is set to
column 1. Finally insert spaces and tabs to
advance the cursor to the automatic margin just

Syntax: :PUSHCH
Semantics: The buffer change flag is saved for the current
buffer and is then cleared. The original state
of the flag can be restored with a :POPCH
command. :PUSHCH and :POPCH commands can be
nested up to 16 levels deep.
9.4.2.73 :Q

Syntax: <Count>:RK<Key>
Semantics: Redefine the key given in <Key> to insert the
character whose value is given in <Count>.
<Key> is a code that identifies the class and
value of the key. It consists of a three digit
decimal number that defines the value. <Key> is
the index into the key mapping table described in
chapter 7 of this manual. Normally the value is
inserted into the command with the ! contruct.
9.4.2.77 :RL
Ruler
Syntax: :RL
Semantics: Switch into ruler definition mode. The cursor is
placed on the first character on the ruler
display in the second line of the screen.
Commands that affect the ruler are:
Right arrow Moves the cursor one character to
the right. The column number can
be read on the status line.
Left arrow Moves the cursor one column to
the left.
- Removes a tab stop at the current
position.
Tab Moves to next tab stop
^H Moves to column 1
T Inserts a tab stop at the current
position
L Sets the left margin to the
current position. When a Return
is entered the cursor will be
indented to the left margin.
R Sets the right margin to the
current position. If the right
margin is reached when entering
text, a new line will be entered
before the word being typed and
the word will be indented to the
word wrap margin.
J Sets the right margin to the
current position. If the right
margin is reached when entering
text, a new line will be entered
before the word being typed and
the word will be indented to the
word wrap margin after adjustment
of the text to the right margin.
W Sets the word wrap margin to the
current position. W fixes the
word wrap position.
A Sets automatic margin control.
The margin is always the leftmost
non-blank position on the current
line.
I Sets the indentation at the
current position.
Space Removes all formatting controls
at the current position.
Digit Load saved ruler number digit.
The rulers are saved in SEDT's
master directory under MS-DOS and
in the directory pointed to by
the logical name SEDT$Dir under
VMS. The name of the ruler file
is RulerN?.Txt where N is the
number of the ruler.
Gold Digit Save current ruler in saved ruler
number digit.
Return Returns from ruler definition
mode to normal edit mode.
If more than one ruler setting is commonly used,
much time can be saved by storing the settings in
rulers 0 through 9. Ruler 0 is loaded by default
and any of the other rulers can be called up with
four key strokes: Gold R Digit Return.
The ruler line controls both left and right
margins. Several options exist for controlling
the margins.
No margin control is done if L, W, R and I are
set in column 1. Lines can be infinitely long
and the cursor is always positioned in column 1
after a Return is typed.
If L is set in a column different from 1 and W is
set in column 1 a Return will cause SEDT to
indent to the column defined by L.
If I is set in a column different from 1 and the
cursor is positioned to the left of the column a
Tab will indent to the column defined by I.
The left and right margin controls work as
follows:
W and R:
When a non-blank character is typed to
the right of R SEDT will insert a Return
in front of the first word that extends
to the right of R and indent to the W
column. The effect will be that text
will be filled between W and R. The fill
command, Gold Keypad 8 will fill text
from the current cursor position to the
end of the current paragraph. Text to
the left of W will be left unaffected.
W and J:
When a non-blank character is typed to
the right of J SEDT will change the
spacing between the current position and
W so that spacing after punctuation
characters will be exactly 2 and after
non-punctuation characters will be 1. A
return will then be inserted before the
first word that extends to the right of
J, after which spaces will be inserted
between words until the right margin is
justified to J. Finally the wrapped word
will be indented to W. Text to the left
of W will be left unaffected.
A and R:
When a non-blank character is inserted to
the right of R a return will be inserted
in front of the first word that extends
to the right of R. The text after the
return will be indented to the same level
as the line just terminated.
A and J:
When a non-blank character is typed to
the right of J SEDT will change the
spacing between all words to the left of
the current position so that spacing
after punctuation characters will be
exactly 2 and after non-punctuation
characters will be 1. A return will then
be inserted before the first word that
extends to the right of J, after which
spaces will be inserted between words
until the right margin is justified to
the same level as the line just
terminated.
W to the right of, or at J/R:
No filling or justification will occur.
A to the right of or at J/R:
When a Return is typed the cursor will be
indented to the same level as the line
just terminated. If the terminated line
is empty the indentation level will
remain unchanged. This mode is
particularly useful for structured
programming.

If the cursor is placed on the first character of
<Target> and the direction is forward make the
substitution. If <Target> is empty use the
current search string, set by @F or :SL. If
<Object> is empty use the current substitute
string. If Target is non-empty insert it in the
current search string. If <Object> in non-empty

Then refresh the display.
On MS-DOS systems COMSPEC is used to locate the
command interpreter which is spawned when the
argument to :SYS is empty.
SEDT uses free memory to contain buffers and
other working areas. Whether enough memory is
available to actually perform the :SYS command
depends on the largest memory requirement that
SEDT has had during the session. It is not
possible to return memory once it has been
claimed and used by SEDT.
9.4.2.117 :TAB
Move to next tab stop
Syntax: {<Count>}:TAB
Semantics: If the current indentation level is to the right
of the cursor insert tab and space characters
until the cursor is placed at the indentation
level. Otherwise insert tab and space characters
until the cursor is at the next tab stop. If no
tab stops are to the right of the cursor do
nothing. Only space characters will be inserted
if the current tab expansion mode is to expand
tabs. The tab expansion is changed with the :TT
command and displayed on the mode line of the
display.
In overstrike mode :TAB will space over any
characters already on the line.

cursor and the select point. Cut operations will
remove the entire select region. Paste
operations will insert the entire paste region at
the cursor position.
In block mode a cut operation will remove all
characters that are within the rectangle
delimited by the cursor and the select point. A
paste operation will insert the paste buffer,
line by line in the buffer starting at the
cursor position and at the cursor column, thus
inserting a rectangle of text into the buffer.
The select region will only have the column at
the select point shown in reverse video.
9.4.2.120 :TC

Sedt Version 4.2 (290)
Appendix C
Error Messages
Error messages fall into four classes: Fatal error
messages that cause Sedt to abort execution, and three levels of
non-fatal errors.
Fatal errors cause Sedt to abort the edit session. If
you have enabled autosaves you may be able to recover the edit
session close to the point where it aborted.
Fatal errors:
Attempt to get before beginning
Internal Sedt error. This is caused by a bug in Sedt.
Could not open key definition file
Sedt could not find the key definition file due to
improper installation or improper operation of Sedt .
Error creating buffer file
Sedt was unable to create a temporary file on disk due to
a lack of disk space available. Correct the situation
and restart the edit session for a recovery.
Error reading data from buffer
Internal Sedt error. This is caused by a bug in Sedt.
Error writing data from buffer
Sedt was unable to write to a temporary file on disk due
to a lack of disk space available. Correct the situation
and restart the edit session for a recovery.
More files than buffers
You attempted to call Sedt with a command that requested
editing more than 1000 different files.
Too many file arguments
For each buffer you can only request an input and an
output file. You supplied more than two file arguments
to the buffer.
Other errors are non-fatal and can optionally ring the
bell to get your attention. This is done with the :EL command.
