The SET (abbreviated SE) command sets options that control other editor
operations. Once set, these options are in effect throughout the rest of
the edit session or until changed by the SET command.

The SET AUTOREPEAT (abbreviated SE AUTOREPEAT) command enables EDT's use
of the DECARM VT100 control sequence to prevent keypad, function and
arrow keys from repeating faster than EDT can update the screen.  If you
do not want EDT to manipulate the VT100's autorepeat feature, use SET
NOAUTOREPEAT (abbreviated SE NOAUTOREPEAT).  On some VT100-class
terminals, SET AUTOREPEAT can cause the arrow keys to repeat at the rate
of 2 per second rather than the usual 30 per second.  With SET
NOAUTOREPEAT the arrow keys repeat faster, but the screen is not updated
for each repeat of the arrow key, since EDT skips intermediate updates
if it gets behind.

Format: SET [NO]AUTOREPEAT

Format: SET CASE { UPPER | LOWER | NONE }

Use the SET CASE (abbreviated SE CA) command on terminals which are
capable of displaying uppercase characters only.  SET CASE instructs EDT
to flag with a preceding apostrophe either the uppercase characters, the
lowercase characters, or neither.  The default for SET CASE is NONE,
which means no characters are flagged.

You can abbreviate the keywords as follows:

    CASE    CA
    UPPER   U
    LOWER   L
    NONE    N

Format: SET COMMAND file-specification

The SET COMMAND (abbreviated SE COMMAND) command is used in a startup
command file to specify the name of the next startup command file to
read.  EDT provides a default file type of ".EDT".  If the file is not
present this command does nothing; otherwise it causes the current
command file to be abandoned and the new one to be read in its place.

Additional information available:

STARTUP

When EDT starts up, it reads the installation default startup command
file.  The name of the file is always EDTSYS.  The default name varies
depending on the system, as follows:

                   Default Name
                   -----------------
VAX/VMS            SYS$LIBRARY:.EDT
RSX-11M & M-PLUS   LB:[1,2].EDT
RSTS/E             LB:.EDT

When opening the file, EDT combines the name and the default name
together into a complete file specification.  On VAX/VMS, therefore, if
the logical name EDTSYS is defined, EDT will read from it rather than
from SYS$LIBRARY:EDTSYS.EDT.

The installation default startup command file should have SET COMMAND
EDTINI at its end, so that the user's initialization file will be read
after the installation default initialization file.   If EDTSYS is not
found, EDT will try again using the name EDTINI, so there is no need for
an installation-default initialization file that just contains SET
COMMAND EDTINI.

Format: SET CURSOR top:bottom

The SET CURSOR (abbreviated SE CU) command, used with screen editing,
sets the limits within which the cursor is allowed to move without
scrolling the screen.

Top and bottom are the line numbers at the top of the screen and the
bottom of the screen.  The line numbers must be in the range of 0 to 21,
with 0 specifying the top of the screen and 21 the bottom.  The default
setting is 7:14, allowing the cursor to move within the middle third of
the screen.  If SET LINES is used to decrease the number of lines shown
on the screen, the top and bottom of the cursor limits must be within
the number of lines on the screen.

Format: SET ENTITY entity-type 'delimiter string'

Where entity-type is one of the following:

    WORD        (abbreviated W)
    SENTENCE    (abbreviated S)
    PAGE        (abbreviated PAG)
    PARAGRAPH   (abbreviated PAR)

The SET ENTITY (abbreviated SE EN) command sets the delimiters for the
user-defined change mode entities.  For the WORD and SENTENCE entities,
the delimiter string is a set of single character delimiters.  For PAGE
and PARAGRAPH, the delimiter is a character string that delimits the
entity.  See HELP CHANGE ENTITIES for explanations of the entities.

Format: SET [NO]FNF

The SET FNF option controls whether or not an informative message is
displayed when you attempt to edit a non-existing file.  NOFNF opens a
new file but gives no message.

Format: SET HELP [file-specification]

The SET HELP (abbreviated SE H) option lets you define which help file
will be accessed when you either give the HELP command or press the HELP
key in keypad mode.  The default device and directory are always as
listed below unless overriden by an explicit device and directory.  SET
HELP without a file specification returns you to the original default
help file.

The following are default specifications for the various systems:

                   File specification  Name      Type
                   ------------------  ----      ----
VAX/VMS            SYS$HELP: .HLB      EDTHELP   .HLB
RSX-11M & M-PLUS   LB:[1,2] .HLP       EDTHELP   .HLP
RSTS/E             LB: .HLP            EDTHEL    .HLP

Format: SET [NO]KEYPAD

The SET KEYPAD (abbreviated SE K) option controls whether or not the
editing keypad is to be used when you are in CHANGE mode.  KEYPAD is set
by default for VT100 and VT52 terminals, which means the alternate
keypad is used to enter change mode commands.  For terminals with
function keys, the function keys can also be used in KEYPAD mode.

The SET LINES (abbreviated SE L) command controls the number of screen
lines used in either of the screen versions of change mode.  Use this
option to reduce the time it takes to refresh the screen image when
editing on slow terminals.

Format: SET LINES n

where n is the number of lines to use.  n must be between 1 and 22.  By
default, n is set to 22 lines.  If the cursor limits are larger than n-1
they are reduced to n-1.  See SET CURSOR.

The SET MODE (abbreviated SE M) command determines which mode of editing
should be entered after all initial processing is complete.  This
command is useful only in the startup command file.

Format: SET MODE { LINE | CHANGE }

By default, EDT enters line mode when the startup processing is
complete.  Use SET MODE CHANGE in your startup command file to cause EDT
to enter change mode when startup processing is complete.

Format: SET [NO]NUMBERS

The SET NUMBERS (abbreviated SE NU) command controls the display of line
numbers on the terminal.  Numbers are set on by default.  If you want to
suppress numbers, use SET NONUMBERS (abbreviated SE NON).

Format: SET PARAGRAPH [NO]WPS

The SET PARAGRAPH (abbreviated SE PARA) command specifies a paragraph as
the text between two delimiters and including any adjacent delimiters
(WPS), or the text between two delimiters (NOWPS).

Format: SET PROMPT prompt-type 'string'

Where prompt-type is either LINE, KEYPAD, NOKEYPAD, HCCHANGE, INSERT,
INSERTN, or QUERY.

The SET PROMPT command allows redefinition of the prompt string that is
displayed in line mode, in keypad mode, in nokeypad mode, in hardcopy
change mode, in line mode when inserting, in line mode when inserting
with NONUMBERS, and with the /QUERY qualifier.

EDT will become confused if the new string for the keypad or nokeypad
prompt causes a net motion of the cursor.  If a <CR><LF> pair is not
included in the new string for any prompt which has it in the default
prompt, these characters will be inserted at the beginning of the new
string.

The SET QUIET (abbreviated SE Q) command controls whether or not the
bell will sound when an error is made in change mode.

Format: SET [NO]QUIET

The quiet option is off (meaning the bell will sound) by default.

The SET REPEAT (abbreviated SE REP) command enables you to use the GOLD
key followed by digits to represent a count.  If you do not want the
ability to use counts, use SET NOREPEAT (abbreviated SE NOREP).  A
warning bell sounds if you attempt to use counts with NOREPEAT set.

Format: SET [NO]REPEAT

By default, REPEAT is enabled.

The SET SCREEN (abbreviated SE SC) command specifies the width of your
terminal.

Format: SET SCREEN w

where w is the width of the screen line.  By default, the screen width
is set to the terminal's width, as reported to EDT by the operating
system.  On VT100-type terminals you can set the width to 80 or 132, and
EDT will adjust the terminal appropriately.  On other CRT terminals you
should only use the terminal's fixed width: 80 for VT52s and 84 for
VK100s.

The SET SEARCH (abbreviated SE SE) command controls several options
related to string searching.

Format: SET SEARCH { GENERAL | EXACT | WPS |
                     CASE INSENSITIVE | CI |
                     DIACRITICAL INSENSITIVE | DI }
                   { [UN]BOUNDED }
                   { BEGIN | END }

Additional information available:

GENERALEXACTWPSCIDIBOUNDEDBEGIN
END

The GENERAL option will cause the case of letters and the presence or
absence of diacritical marks to be ignored in search strings.  GENERAL
is the default.

The EXACT option will require all characters to match exactly, including
the case of letters and the presence of diacritical marks, in search
strings.

The WPS option will cause a case-independent string match for lowercase
letters in the search string, and a case-dependent match for uppercase
letters in the search string.

The CI option will cause the case of letters to be ignored in search
strings, but not the presence of diacritical marks.  CI is an
abbreviation for CASE INSENSITIVE.

The DI option will cause diacritical marks on letters to be ignored in
string searches, but not the case of the letters.  DI is an abbreviation
for DIACRITICAL INSENSITIVE.

The BOUNDED (abbreviated BO) option will cause the search to be bounded
by a page delimiter.  By default, the search is unbounded, which means
that the entire buffer will be searched.  This option has effect only in
change mode.

The UNBOUNDED (abbreviated U) option causes the search not to be bounded
by a page delimiter, which means that the entire buffer will be
searched.  This is the default.  This option has effect only in change
mode.

The BEGIN (abbreviated B) option causes the cursor to be left at the
beginning of the search string when it is found. This is the default.
This option has effect only in change mode.

The END (abbreviated E) option causes the cursor to be left at the end
of the search string when it is found. By default, the cursor is left at
the beginning. This option has effect only in change mode.

The SET [NO]SUMMARY command controls whether or not summary information
about a file written with the WRITE or EXIT commands will be typed out.
The default is SUMMARY, which means that summary information is typed.

Format: SET [NO]SUMMARY

The SET TAB (abbreviated SE TA) command enables the structured tab
feature and sets the logical tab size.

Format: SET [NO]TAB n

where n is the number of columns in a logical tab stop.

With the structured tab feature, EDT keeps a counter of the tab level,
which is set to 1 when the SET TAB command is issued. When you use the
tab key in change mode at the beginning of a line, EDT inserts enough
tabs and spaces to move the cursor to the column defined by the level n
times the tab size.  Change mode nokeypad commands can alter the tab level.
The structured tab feature is disabled by default.

The tab size set by the tab command is also used by the TABS ADJUST
command.

Format: SET TERMINAL { HCPY | VT100 | VT52 }
                     { SCROLL | NOSCROLL }
                     { EDIT | NOEDIT }
                     { EIGHTBIT | NOEIGHTBIT }

The SET TERMINAL (abbreviated SE TE) command identifies to EDT the type
of terminal you are using.  Normally, EDT will set the terminal type by
asking the operating system what type it is.  If it does not appear to
have set the type correctly, you can use the SHOW TERMINAL command to
see what EDT thinks your terminal is and the SET TERMINAL command to
correct it if necessary.  If your terminal is not a VT100 or a VT52, it
should be set to HCPY (hardcopy).

Additional information available:

HCPYVT100VT52SCROLLNOSCROLLEDITNOEDIT
EIGHTBITNOEIGHTBIT

HCPY stands for hardcopy.  EDT considers a terminal hardcopy if it is
not a VT100 or a VT52.  On such terminals change mode does not use the
screen as a window onto your buffer, but instead shows you the current
line with the cursor position indicated.  You type NOKEYPAD commands and
EDT will keep you informed by printing the current line after each
command.

The VT100 is a family of terminals, all based on the original VT100
terminal. This class of terminals includes the VT101, VT102, VT125,
VT131 and VT132.

The VT52 terminal is the predecessor of the VT100 family.  It does not
have reverse video, and has fewer keys in its keypad.

This option indicates that your terminal has scrolling regions and EDT
may use them.  This is the default for most VT100 terminals.

This option indicates that either your terminal does not have scrolling
regions or EDT should not use them.  This is the default for VT52
terminals.

This option indicates that your terminal has the screen editing features
of the VT102.  These are IL (insert line), DL (delete line), ICM (insert
character mode) and DCH (delete characters).

This option indicates that your terminal does not have the screen
editing features of the VT102.

This option indicates that your terminal contains the DEC Multinational
Character Set, which extends ASCII to include letters with diacritical
marks and other characters used in Europe.

This option indicates that your terminal does not contain the DEC
Multinational character set.  On such a terminal characters which cannot
be displayed directly are displayed using <>.

Format:  SET TEXT text-type 'string'

Text-type is one of the following:

    PAGE
    END

The SET TEXT command allows you to define the displayed string to
indicate a formfeed character (SET TEXT PAGE), and the displayed string
to indicate the end of the buffer (SET TEXT END).  The string can not
contain control or escape characters.

The SET TRUNCATE (abbreviated SE TR) command controls the handling of
long lines in change mode.

Format: SET [NO]TRUNCATE

By default, truncate mode is set, which means long lines will be
truncated on the display (the actual text is not altered).  If you turn
off truncate mode by using SET NOTRUNCATE, long lines will be wrapped to
as many screen lines as are necessary to display the entire line.

The SET VERIFY (abbreviated SE V) command controls the listing of
commands that are executed from the startup command file or from a
macro.

Format: SET [NO]VERIFY

Verify is off by default, which means the lines are not typed.  If you
turn it on, each command line is typed as it is executed.

Format: SET WORD [NO]DELIMITER

The SET WORD (abbreviated SE W) command enables you to specify that the
word delimiters be considered words by themselves (NODELIMITER), or
considered as part of the word they delimit (DELIMITER).  The default is
DELIMITER.

Format: SET [NO]WRAP n

The SET WRAP (abbreviated SE W) command enables word wrapping and
specifies the right margin.  Word wrapping is a feature of EDT that
automatically insert carriage returns when the text you are typing
exceeds the right margin.  Word wrapping is in effect in change mode
only and only if you have used the SET WRAP command.

The SET WRAP command also sets the right margin for the nokeypad mode
FILL commmand.

SET NOWRAP (abbreviated SE NOW) disables the word wrapping feature.
