+
+
+			      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.

+
+
+	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:
+

+
+	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)
+
+				To  not  perform  the  actions	described
+				under CONTEXT=SAVED.
+
+			CONTEXT=CHECK
+
+				Do  not    save  a  context  (.CTX)  file
+				automatically, but check for the presence
+				of one when loading  a file and use it of
+				it is found.
+
+	2.1.6 	        CONTROLZ=ON
+
+				Causes	Sedt  to  terminate  all    files
+				written with a control Z (EOT) character.
+
+			CONTROLZ=OFF (Default)
+
+				Causes	  Sedt	to  not  terminate  files
+				written with a control Z (EOT) character.
+
+	2.1.7 	        CURSOR=FREE
+
+				The cursor can move freely on the screen.
+				Lines  will  be  padded  to   the  cursor
+				position.
+
+			CURSOR=RESTRICTED (Default)
+
+				The  cursor  can  only move to	positions
+				within the file.
+
+	2.1.8 	        CURSORLINE=FIXED
+
+				Causes	Sedt  to  keep the cursor on  the
+				middle	line  of the editing window.  The
+				benefit is  ease  of  finding the current
+				position and always  being  able  to  see
+				several lines above and below the cursor.
+
+			CURSORLINE=FLOATING (Default)
+
+				Causes Sedt to float  the  cursor through
+				the editing window.  The benefit is fewer
+				screen scrolls.
+
+	2.1.9 	        DEFINITIONS=ON
+
+				When  a  key  with an associated function
+				definition  is	pressed  in response to a
+				prompt the definition will be inserted.
+
+			DEFINITIONS=OFF (Default)
+
+				When a	key  with  an associated function
+				definition is pressed  in  response  to a
+				prompt the character associated  with the
+				key is inserted.
+
+	2.1.10	        DIALOG=ON
+
+				Windows and  GEM versions will use dialog
+				boxes  to prompt  for  input  instead  of
+				using the bottom line of the display.
+
+			DIALOG=OFF
+
+				Windows  and GEM versions  will  use  the
+				bottom line of the display  to prompt for
+				input.
+
+	2.1.11	        EGA43=ON
+
+				Causes Sedt to switch the display into 43
+				line  mode.  Unpredictable results can be
+				expected on other than EGA displays.
+
+			EGA43=OFF (Default)
+
+				Turns off 43 line mode.
+
+	2.1.12	        FILES=ON
+
+				The  names  of	the  key  definition  and
+				function definition files are appended to
+				the file dump, which  is  in  the current
+				working directory.
+
+			FILES=OFF (Default)
+
+				Nothing.
+
+	2.1.13	        FONTSIZE=<number>
+
+				Causes Sedt  to default to a font that is
+				close to <number> pixels high.
+
+	2.1.14	        GOLD
+
+				Has no	effect.   Setting the gold key is
+				done in the  key  mapping  file  starting
+				with version 4.0.
+
+	2.1.15	        JOURNALING
+
+				Has  no  effect in the current version of
+				Sedt and exists only for historic reasons.

+
+			KEYBOARD=SLT
+
+				Forces	Sedt to assume	that  the  system
+				uses a Compaq SLT keyboard.
+
+			KEYBOARD=<type>
+
+				Forces Sedt to use <type>  as  the prefix
+				for keyboard map and help files.
+
+	2.1.17	        MAPPING=EDT (Default)
+
+				Use  .EDT    extensions    on	key  map,
+				definition and help  files.
+
+			MAPPING=WPS
+
+				Use    .WPS   extensions  on  key    map,
+				definition  and  help  files.
+
+			MAPPING=<String>
+
+				Use .<string>  as  extentions on key map,
+				definition and help files.
+
+	2.1.18	        MAXSCROLL=<Number>
+
+				Limits	scrolling  during cursor movement
+				to <Number> lines.
+
+	2.1.19	        MODE=<Hex Number>
+
+				Use  video  mode  <Hex	Number>  on    PC
+				compatible systems.   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.
+
+	2.1.20	        MOUSE=ENABLED (Default)
+
+				Enabled use of the mouse from Sedt.  Sedt
+				will  try  to  detect  the  presence of a

+
+	2.1.22	        PALETTE=<hex string>
+
+				Causes	Sedt to use the characters  given
+				in  <hex  string> as it's palette.   Each
+				pair  of    hex   digits  determines  the
+				attribute character as	defined  for  the
+				IBM Color Graphics Adapter.  The position
+				of  the  pair  defines	the  use  of  the
+				attribute character:  (Sedt only uses the
+				REVERSE and BOLD attributes).

+
+
+	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:
+

+		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.

+
+		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

+
+			      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:
+
+			1		<F1>
+			2		<F2>
+			3		<F3>

+
+		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

+			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

+
+				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

+
+			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

+	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.
