			      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:

			FUNDEF.yyy

		Key mapping files are:

			For VMS:

		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 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)

				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.

	2.1.16	        KEYBOARD=STANDARD

				Forces Sedt  to  assume  that  the system
				uses the original PC and XT keyboard.

			KEYBOARD=LK250

				Forces Sedt to assume that the system has
				an LK250 keyboard attached.

			KEYBOARD=NEW
			KEYBOARD=ENHANCED

				Forces Sedt to assume that the system has
				the new style IBM keyboard attached.

			KEYBOARD=CONVERTIBLE

				Forces Sedt to assume that the system has
				an  IBM  keyboard   convertible  keyboard
				attached.

			KEYBOARD=AT

				Forces	Sedt  to  assume that the  system
				uses an original AT style keyboard.

			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
				mouse  and  enable  the  use of the mouse
				cursor.

			MOUSE=DISABLED

				Sedt will  not	use a mouse even if it is
				present.

	2.1.21	        NUMLOCK=SET  (Default  if the  Num  Lock  key  is
				mapped by the keyboard map file)

				Saves  the  Num Lock state when  Sedt  is
				entered and then  sets	it.  On exit from
				Sed the Num Lock state is retored.

			NUMLOCK=CLEARED

				Saves  the  Num  Lock  state when Sedt is
				entered and then clears it.  On exit from
				Sedt the Num Lock state is restored.

	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).

				NORMAL
				BOLD
				BLINK
				BOLD BLINK
				UNDERLINE
				BOLD UNDERLINE
				BLINK UNDERLINE

	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.

	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.

	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.

	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>
			4		<F4>

			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

	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

				      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.

				   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.

			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.

				      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

				    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.

			In  replace  mode  the	character  at the  cursor
			position  is  replaced	by  the  character  being
			inserted.   If	the  cursor  is at the end of the
			line the character  will  be inserted rather than
			replaced.  If the  cursor  is  at a tab character
			the tab will be expanded  to  spaces  before  the

			Save and clear buffer change flag

	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

	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.

			a  single  keystroke if <Command> was  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

	9.4.2.119		       :TB

			       Toggle Block Mode

	Syntax: 	:TB

	Semantics:	Toggle between block and line cut and paste.

			In line mode  (shown  by  line on the mode line),
			the select region is  all  characters between the
			cursor and the select point.  Cut operations will
			remove	  the  entire  select  region.	    Paste
			operations will insert the entire paste region at

				   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.
