Information about “DR-EDIT”
program editing is like wordprocessing. DR-EDIT emulates many common
wordprocessor and editor features and is recommended for computer users
with at least a moderate technical knowledge of small computers and
their programming. DR-EDIT creates or edits ASCII files and offers
``horizontal scrolling'' to extend the screen's usable width from 80
characters to 32K. It has an overall length limit of 9,999 lines (this
version is limited to 200 lines), the ability to concurrently edit two
files, and a macro capability to expedite routine or repeated
manipulations. A special algorithm is used that makes DR-EDIT
especially useful with artificial intelligence languages such as LISP,
PROLOG, and C.

11..11 DDRR--EEDDIITT ------ AAnn iinnttrroodduuccttiioonn
D-R Software is pleased to introduce a microcomputer program editor
that has been drastically needed for a long time in the programming
community. By emulating the best features of existing word processors
and editors, and by also adding new features of its own, DR-EDIT has
emerged to literally take the place of existing software of its kind by
taking the chore out of editing program text as well as increasing the
productivity of its users.
D-R Software has put painstaking efforts into the design of this editor
by exploring the special minute-by-minute needs of programmers and then
implementing this knowledge into the production of an editor that uses
the memory-mapped video and expanded memory capabilities of the
computer being used. In addition, some especially attractive features
have been added that addresses some of the day to day problems of the
programmers that use the current artificial intelligent languages.
11..22 TThhee rraannggee ooff DDRR--EEDDIITT
DR-EDIT was developed for use on the MS-DOS/PC-DOS operating system(s).
Within the world of this operating system, DR-EDIT can be used to
create and edit any ASCII file, either program text files or data
files. This editor is also sensitive to the use of subdirectories and
can edit a file in a particular subdirectory even if the user is not
currently logged in to it.
Some of the features that make DR-EDIT useful for editing any ASCII
file are listed below:
1. DR-EDIT offers "horizontal scrolling" extending the width
of the screen beyond the physical limit of 80 characters.
The maximum length of a line is approximately 32K which
is most likely more than will ever be necessary.
2. Limits to the length of a file are related to the amount
of memory available on the machine with an overall limit
of 9,999 lines. This too is probably more capacity than
will be needed during normal use.
3. DR-EDIT offers the capability to edit two files at the
same time (concurrently). This allows you to "flip" back
and forth between the two files which becomes mighty
handy in certain circumstances.
4. Another feature that makes this editor a useful and
productive tool is its ability to build macro-
instructions. This feature allows you to execute a
sequence of commands with a single keystroke using the
function keys.
- 5 -
An additional feature that makes this editor useful in the artificial
intelligence world is the use of an algorithm that will match certain
special characters such as parentheses(`()'), brackets(`[]'), and
braces(`{}'). This is particularly useful when a programmer is trying
to keep track of these characters in programming languages such as
LISP, PROLOG, and perhaps even C.

22..11 LLOOAADDIINNGG DDRR--EEDDIITT
DR-EDIT is supplied on a floppy disk under the file name DREDIT.EXE.
You may copy this file onto any disk or any subdirectory that you wish.
To start the program, type the following command at the DOS prompt:
C> _D_R_E_D_I_T_ _<_f_i_l_e_n_a_m_e_>
The file name is optional in the respect that if it is not entered at
the command line level, you will be prompted for it upon entering the
program. You may enter a file name in the form that corresponds to the
forms that are valid for a normal DOS file. That is, you may specify a
drive, a subdirectory, and an extension along with the file name. An
example of a valid file name is:
_C_:_\_G_A_M_E_S_\_E_X_A_M_P_L_E_._B_A_S
22..22 CCRREEAATTIINNGG AA NNEEWW FFIILLEE
If you load DR-EDIT and include a file name that does not exist on the
disk, then DR-EDIT will create a new file. You may then type text.
All the text that is typed in, will be in RAM and will not be saved to
disk until you request to save it with the <Q>uit command (See section
3.15 for the QUIT command).
22..33 EEDDIITTIINNGG AANN EEXXIISSTTIINNGG FFIILLEE
If the file name that is entered exists on the disk, then DR-EDIT will
read that file in its entirety and place the information into RAM for
editing. The editing work that is done affects ONLY the text buffer
(RAM), without accessing the disk unless you, the operator,
specifically request disk access.
When you terminate the DR-EDIT session with the QUIT command, the
following events take place automatically. The existing file that is
on the disk is renamed to a file with the same name except with a .BAK
extension. Then the information that resides in RAM is written to the
file name that you specified.
22..44 TTHHEE TTEEXXTT BBUUFFFFEERR
The size of the text buffer area depends on the amount of memory that
is available on the system. DR-EDIT uses the memory that is not
already being used by the operating system and the program.
- 7 -
In addition to the above limitation, the program calculates a number
from the amount of memory left that serves as a maximum number of lines
that you may enter for a single file. This number is really only
relevant on systems with low memory (256K or less). The maximum number
of lines on any file can only go up to 9,999 lines.
22..55 CCOOMMMMAANNDDSS
Upon entering DR-EDIT, the system is in the COMMAND mode of operation.
In this mode, you may perform a variety of different functions by
pressing almost any key on the keyboard. Care should be taken to
remember what mode you are as you type on the keyboard.
To type in text, you must enter one of two other modes in the system
--- INSERT mode or CHANGE mode. You may get into these modes by
pressing the 'I' or 'C' keys respectively while in COMMAND mode.
You will know what mode you are in by looking at the status line which
is at the top of the display.
You may always return to the COMMAND mode by pressing the <ESC> key.
This may even be done when you have entered a command that has
subsequent questions.
In addition to the commands in COMMAND mode, there are other commands
that may be executed no matter what mode the system is in. These
commands are referred to as 'immediate commands'.
22..66 DDRR--EEDDIITT WWIINNDDOOWWIINNGG SSYYSSTTEEMM && CCUURRSSOORR MMOOVVEEMMEENNTT
DR-EDIT has a sophisticated windowing system that allows you to
randomly move around within a file. You may think of your file as a
painters canvas of which you can only see a small portion called a
viewport. You have control over that viewport and may move it around
on the canvas displaying any section of your canvas (file) that you
want. This cursor movement is accomplished through the use of the arrow
keys and as side effects to certain commands that are executed in the
editor.
The current location within the file being edited is always displayed
in the status line that is displayed at the top of the screen.
Besides the functions associated with the arrow keys, there are several
other functions that can be used to alter the position of the cursor on
the screen and/or change the entire viewport area. Some of these are
listed below with a brief description of each. Sometimes these
functions have different key assignments depending on the machine you
are using. To see what keys are associated with the desired functions
on a particular machine, see Appendix `A'.
1. The paging keys make it possible to move from screen to
screen.
- 8 -
2. The <TAB> key allows movement across a line in intervals
which are user-definable.
3. The <B> command and the <E> command described in section
III will move the cursor to the beginning or end of a
screen or file.
4. <CTRL-J> (linefeed) will move the cursor to the beginning
or end of the current line.
There are other commands that will change the display due to side
effects. These will become apparent through the use of the editor.

33..11 BB ------ BBeeggiinnnniinngg ooff SSccrreeeenn,, BBeeggiinnnniinngg ooff TTeexxtt
This command is used to move the cursor to the HOME position of the
screen or to move the cursor as well as the viewport to the home
position of the file.
By pressing the <B> key once, the cursor is positioned at the upper
left hand corner of the screen. If you immediately press it again, the
viewport is moved to the beginning of the file and the cursor is placed
at line 1 - column 1.
33..22 CC ------ CChhaannggee mmooddee
By pressing the <C> key, the editor enters the CHANGE mode. In this
mode, everything you type will overwrite what is immediately at the
cursor position.
Like the INSERT mode, you can type beyond the 80 columns that appear on
the screen. The screen will shift horizontally when there is no more
room to place text.
The <BACKSPACE> key places a space over the character to the left of
the cursor and then positions the cursor at that position.
You may also enter the change mode by pressing the <INS> key. This key
toggles back and forth between INSERT mode and CHANGE mode.
You may exit the CHANGE mode at any time simply by pressing the <ESC>
key.
33..33 DD ------ DDeelleettee aa cchhaarraacctteerr
The delete command deletes the character under the cursor and moves the
remaining characters on the line to the left one space.
33..44 EE ------ EEnndd ooff SSccrreeeenn,, EEnndd ooff TTeexxtt
This command performs the opposite task as the <B> key (see section 3.1
above). By pressing any one of these keys once, the cursor will move
to the bottom left corner of the current screen. By immediately
pressing the key a second time, the cursor will be positioned to the
end of the file being edited.
- 10 -
33..55 FF ------ FFiillee ooppeerraattiioonn
The file operation command has a number of different options that are
associated with it. With this command, you may read from a file on the
disk, write to a file on the disk, erase a file on the disk, get a
directory listing, enter/change the buffer area, or kill the alternate
buffer (if it exists).
Upon pressing the <F> key, DR-EDIT will give the following prompt:
FILE OPERATION (R, W, E, D, B, K):
You then have the option of the operation that you desire. Below is a
list of the available options and the instructions on their usage.
R => (read from a file)
The <R> command of the file operation allows the user to
read from an existing file on the disk and place the
new text at a specific location in the text buffer. The
following prompts will be given displayed on the command
line for user response:
FILE NAME:
BEGINNING OF SECTION: END OF SECTION:
INSERT AT LINE:
W => (write to a file)
Next, the <W> command allows you to write a section of
text from the buffer to a file on the disk. The
following information will be prompted for:
FILE NAME:
BEGINNING OF SECTION: END OF SECTION:
It is important to note here that if the file name given
above is the name of a file that already exists, DR-EDIT
will append the section to the end of that file. That
is, if you want to replace an existing file with the
section indicated, you must first erase that file using
the next option (E).
- 11 -
E => (erase a file)
<E> is the command to erase a file from the disk. You
will be prompted for the file to erase as shown below:
FILE NAME:
If that file exists, you will be prompted with:
ARE YOU SURE? (Y/N)
This is your last chance to stop. If you answer <Y>es,
the file that you named will be deleted from the disk.
D => (directory)
The <D> command will display the directory listing of
the specified disk and file/pattern. The file pattern
mask can be any legal MS-DOS file specification
including wildcards (ie. *.*, EXAMPLE.?AS). Enter the
pattern to the following prompt:
DIRECTORY PATTERN:
B => (buffer toggle)
The buffer toggle is a very useful feature of DR-EDIT.
It gives the capability of editing two files
simultaneously by setting up an alternate text buffer
from which you can toggle back and forth.
If an alternate buffer has already been established,
this command does nothing more than act as a toggle to
move from one text buffer to another.
If you have not previously set up the alternate buffer,
this command will prompt you for the name of the second
file you wish to edit,
FILE NAME:
and then read it into its own buffer.
K => (Kill alternate buffer)
This command will allow you to kill the alternate buffer
from memory. This will give you the ability to bring in
another file into the alternate buffer area.
When this command is executed, the editor will give you
the option of saving the alternate buffer before it is
killed from memory with the following prompt:
SAVE IT FIRST? (Y/N)
- 12 -
33..66 HH ------ DDiissppllaayy HHeellpp SSccrreeeenn
By pressing the <H> key, DR-EDIT displays a single help screen on the
display. This screen contains each of the commands in the DR-EDIT
system with a brief description of what the command does.
You may return to the editor by simply pressing any key.
33..77 II ------ IInnsseerrtt mmooddee
When this key is pressed, the editor enters the Insert mode. While in
insert mode, anything you type will be inserted into the text by
opening a space at the current cursor position and moving everything to
the right of the cursor one space.
If the <BACKSPACE> key is pressed while in Insert mode, the character
immediately to the left of the cursor is deleted and everything from
the current cursor position to the end of the line is moved to the left
one space.
If the <RETURN> key is pressed, a line is opened up following the line
on which the cursor resides and the cursor is placed at column 1 of
the new line that was created.
33..88 JJ ------ JJuummpp ttoo aa ssppeecciiffiieedd lliinnee
This command allows you to move the cursor and viewport to a specific
line of the file being edited. When this command is executed, DR-EDIT
will ask:
LINE:
Enter the number of the line that you want to "jump" to and press
<RETURN>. The editor will then move to that line.
33..99 KK ------ KKiillll aa lliinnee
The <K>ill command deletes the line where the cursor lies. The
following lines are then moved up one line. To accomplish this, place
the cursor on the line to be deleted, and while in COMMAND mode, press
the <K> key on the keyboard.
33..1100 LL ------ LLoowweerr CCaassee
The <L> command changes all the characters on the line where the cursor
is to lower case.
- 13 -
33..1111 MM ------ MMoovvee//CCooppyy aa sseeccttiioonn ooff tteexxtt wwiitthhiinn tthhee bbuuffffeerr
<M>ove is the command to move/copy a block of text from one place to
another within the current text buffer. By pressing the <M> key in
COMMAND mode, you will be prompted:
BEGINNING OF SOURCE:
ENDING OF SOURCE:
DESTINATION:
After answering the above questions, you can decide whether you want to
copy the section, keeping the source section where it is, or move the
section and deleting the source section from the buffer. DR-EDIT will
prompt you for this with:
REMOVE SOURCE (Y/N)?
By answering <Y>es, the section will be copied to the desired place and
the number of lines copied will be deleted starting at the beginning
line of the source section.
If you answer <N>o, the section will simply be copied to the desired
place.
33..1122 NN ------ TTooggggllee LLiinnee NNuummbbeerrss
By pressing the <N> key, reference line numbers will be placed to the
left of the text display. These line numbers are extremely helpful
when referencing sections of text or looking for a specific line. This
key acts as a toggle by displaying the numbers if they are not present
and removing them if they are.
33..1133 OO ------ OOppeenn aa lliinnee
The <O> command opens a line of text before the line where the cursor
is currently located. This is useful in inserting new lines in the
text buffer.
33..1144 PP ------ PPrriinntt aa sseeccttiioonn ooff tteexxtt oonn tthhee pprriinntteerr
DR-EDIT has the capability of printing a section of text in the text
buffer to the printer. This is done by pressing the <P> key while in
command mode. You will then be prompted for the section of text that
you desire to print:
BEGINNING OF SECTION: END OF SECTION:
Upon answering the above prompts, DR-EDIT will then print the desired
section.
- 14 -
33..1155 QQ ------ QQuuiitt
The <Q>uit command allows you to exit the DR-EDIT system and returns
control to the MS-DOS/PC-DOS operating system. By pressing the <Q>
key, the following prompt will be displayed:
QUIT (S, A, N)?
The sub-commands (S, A, N) are shown below along with their meanings
and other pertinent information.
S => (Save text buffer)
By entering <S> to the above prompt, DR-EDIT will enter
the saving process. If there is no alternate buffer
active, the system will immediately save the buffer and
exit to the operating system. However, if there is an
active alternate buffer, the following prompt will be
displayed for each buffer:
SAVE PRIMARY BUFFER? (Y/N)
or
SAVE ALTERNATE BUFFER? (Y/N)
A <Y>es response will cause the system to save buffer
while a <N>o response will abort the text buffer.
After the buffers have been either saved or aborted,
DR-EDIT will exit to the operating system.
A => (Abort text buffer)
The <A> option of the QUIT command immediately aborts
the text buffer and returns to the operating system.
N => (No abort or save desired)
This option is synonimous to pressing the <ESC> key.
It simply returns you to the COMMAND mode of DR-EDIT
for further text editing.
33..1166 RR ------ RReemmoovvee sseeccttiioonn ooff tteexxtt
This command will remove a specified section of text from the current
text buffer. You will specify the section by giving the beginning and
ending line numbers to the following prompt:
BEGINNING OF SECTION: ENDING OF SECTION:
DR-EDIT will then delete the section including the two lines specified.
- 15 -
33..1177 SS ------ SSeeaarrcchh aanndd RReeppllaaccee
The <S>earch command is used to search for (and possibly replace) a
given string of characters. DR-EDIT will prompt for the string to
search for, the string to replace it with, the extent of the search,
and whether you want to globally search and replace (non-stop replace
ment) or view and execute the replacement manually.
The search process searches the desired section of the file for a
series of characters that match the pattern entered in the search
string. This pattern can contain a series of letters and digits, plus
the following wildcard characters:
# => represents any digit
! => represents any upper-case or lower-case letter
? => represents any character
\ => the character following this character is treated
as a literal character and does not serve as a
wildcard character.
When the <S> key is pressed, the following prompts are displayed:
SEARCH STRING: => Enter the string that you wish to search
for in either upper or lower case.
REPLACE STRING: => Enter the exact string that you want to
replace the search string with.
EXTENT OF SEARCH? (A, C, L): => This prompt gives you
several options on how much of the file
you want to search. The three options
are listed below:
A -> Search the entire (ALL) file starting at
the beginning.
C -> Search from the cursor position to the
end of the file.
L -> Search a specific line section of the
file. You will be prompted for the
beginning of the section and the end of
the section.
NON-STOP REPLACEMENT? (Y/N) => Answering <Y>es to this
prompt will search the specified area
replacing every occurrance of the search
string with the replacement string.
Answering <N>o means you will have to
manually perform the search process using
the <CTRL-S> and <CTRL-X> commands
described in section IV.
- 16 -
33..1188 TT ------ TTaabb CCoonnttrrooll
DR-EDIT has a mechanism installed which allows you to manually set your
own tab stops. This is done by placing the cursor on the column that
you want the tab stop to be set at and pressing the <CTRL-T> key (ie.
press the <CTRL> key and the <T> key simultaneously). This is also
explained in the following IMMEDIATE COMMAND section under the <CTRL-T>
command (4.15).
When DR-EDIT is started, the default tabs are placed at every eighth
column. To change this, you would use the <CTRL-T> procedure mentioned
above. However, to return the editor to the original default tabs, the
<T>ab command will perform this task.
Another thing that the tab control command does is to expand any tab
characters (ASCII character nine (9)) to eight spaces. This is an
irrelevant feature if all you use is the DR-EDIT system, as DR-EDIT
never puts in tab characters anyway. However, other editors may put
these tab characters in and if you are not a lover of these characters,
this command may be a favorite of yours.
When the <T> key is pressed, the following prompt is displayed:
SELECT TABULATE OPTION? (D, X)
You then can choose between the two options that are listed. These are
described below:
D => (Default tabs)
This option returns the tab stops to their default
status.
X => (Expand tabs)
This option expands all tab characters that may be
present in the file to eight spaces.
33..1199 UU ------ UUppppeerr ccaassee
The <U> command changes all the characters on the line where the cursor
is to upper case.
33..2200 ZZ ------ ZZaapp ttoo eenndd ooff lliinnee
This command deletes all the characters on the line where the cursor
lies from the cursor position to the end of the line including the
character under the cursor.
- 17 -
_II_VV_.._ _ _II_MM_MM_EE_DD_II_AA_TT_EE_ _CC_OO_MM_MM_AA_NN_DD_SS
Immediate commands are commands that are executed immediately upon
pressing the key. Most of these commands are executed by pressing the
<CTRL> key and a letter at the same time and are different from normal
commands in the fact that they can be executed when the system is in
INSERT mode and CHANGE mode, as well as COMMAND mode.
44..11 CCTTRRLL--AA ------ AAppppeenndd lliinnee
The <CTRL-A> command will combine the line immediately following the
line where the cursor is with the line that the cursor is currently
sitting on.
44..22 CCTTRRLL--BB ------ BBeeggiinnnniinngg ooff bblloocckk
When <CTRL-B> is pressed, the line where the cursor is currently
sitting will be used as the beginning line in some of the commands that
were described in section III. Some of these commands are <M>ove,
<R>emove, <P>rint, and <F>ile operation. When these commands are
executed, the line number of the beginning of block will be used as the
default value for the prompt:
BEGIN. OF SECTION:
44..33 CCTTRRLL--CC ------ CChhaannggee CCaassee
When this key is pressed, the case of the character that resides under
the cursor will be reversed and the cursor will be moved one space to
the right. That is, if the character is an upper case character, it
will be changed to lower case, and if the character is a lower case
character, it will be changed to upper case.
44..44 CCTTRRLL--DD ------ DDeelleettee aa wwoorrdd
The <CTRL-D> key will delete all the characters from the cursor
position to the next special character (i.e. the end of the word) and
move all the characters to the right of the deleted word to the left.
- 18 -
44..55 CCTTRRLL--EE ------ EEnndd ooff bblloocckk
When <CTRL-E> is pressed, the line where the cursor is currently
sitting will be used as the ending line in some of the commands that
were described in section III. Some of these commands are <M>ove,
<R>emove, <P>rint, and <F>ile operation. When these commands are
executed, the line number of the end of block will be used as the
default value for the prompt:
END OF SECTION:
44..66 CCTTRRLL--GG ------ GGeett aa lliinnee
<CTRL-G> will get the line where the cursor is positioned and put it in
a temporary storage area. This line can then be recalled at any time
using the <CTRL-Y> (Yank) command.
44..77 CCTTRRLL--II ((TTAABB)) ------ TTaabb
When the <TAB> key is pressed the cursor is positioned at next defined
tab stop on the current line. Tab stops may be set using the <CTRL-T>
key which is described later in this section.
NOTE: When DR-EDIT is in INSERT mode, spaces will be inserted and all
the characters to the right of the cursor will be shifted to the
right.
44..88 CCTTRRLL--JJ ((LLIINNEEFFEEEEDD)) ------ BBeeggiinnnniinngg,, EEnndd ooff lliinnee
If the cursor is not positioned at column one of the current line,
pressing this key will move the cursor to this column.
However, if the cursor is at column one, this key will move it to the
end of the line.
DR-EDIT also has the feature that if the <SHIFT> key and the <LINEFEED>
key are pressed at the same time, the cursor will also move to the end
of the line.
- 19 -
44..99 CCTTRRLL--KK ------ KKiissss mmaattcchhiinngg ssyymmbbooll
When the <CTRL-K> key is pressed while the cursor is positioned over
one of the following characters:
( [ { } ] )
DR-EDIT will attempt to find its match and kiss it for approximately
two seconds.
For example, If the cursor is sitting on a '(' and a <CTRL-K> is
pressed, then the system would attempt to find a ')' that is its match.
This means that if there are parentheses (or any other of the above
symbols) that are nested, ie. (a + (b * c)), the system will kiss the
correct symbol.
44..1100 CCTTRRLL--LL ------ LLeefftt oonnee wwoorrdd
Pressing <CTRL-L> will move the cursor to the left one word. If the
cursor is already at the beginning of the line, no action will be
taken.
44..1111 CCTTRRLL--NN ------ TTooggggllee lliinnee nnuummbbeerrss
By pressing the <CTRL-N> key, reference line numbers will be placed to
the left of the text display. These line numbers are extremely helpful
when referencing sections of text or looking for a specific line. This
key acts as a toggle by displaying the numbers if they are not present
and removing them if they are.
Note: This is the same command as the <N> command described in Section
III (3.12).
- 20 -
44..1122 CCTTRRLL--PP ------ AAuuttoommaattiicc ppaarreenntthheessiiss mmaattcchhiinngg sswwiittcchh
<CTRL-P> is a switch that turns on and off the automatic parenthesis
matching feature of DR-EDIT. When the system is in INSERT mode or
CHANGE mode and one of the following characters is typed:
( [ { } ] )
DR-EDIT will attempt to find its match and kiss it for approximately
one second.
This is basically the same feature as the <CTRL-K> feature described
above, except that it happens automatically when the characters are
typed. While the system is searching for a match, the message:
MATCHING
will appear on the command line. You may abort the matching process
simply by typing the next character in your text.
44..1133 CCTTRRLL--RR ------ RRiigghhtt oonnee wwoorrdd
Pressing <CTRL-R> will move the cursor to the right one word. If the
cursor is already at the end of the line, no action will be taken.
44..1144 CCTTRRLL--SS ------ SSeeaarrcchh
The <CTRL-S> key will search for the next occurance of search string
defined in the SEARCH command from section III (3.16). It begins its
search at the cursor position.
44..1155 CCTTRRLL--TT ------ SSeett ttaabb ssttoopp
This command sets a tab stop at the cursor position. Whenever the
<TAB> key is pressed, the cursor will stop at each of the tab positions
defined.
To remove the defined tab stops, and return the system to its default
status, use the <T>ab command described in section III (3.17).

44..1166 CCTTRRLL--UU ------ UUnnkkiillll
DR-EDIT has a method of restoring lines that were deleted using the
<K>ill command (Section III - 3.9). There is a 30 line revolving
buffer that allows you to recover these deleted lines.
To restore a line, place the cursor where you want the restored line to
go and press <CTRL-U>. The line will be recalled from the buffer and
will be placed before the line where the cursor is sitting.
NOTE: This command will not retrieve lines that were deleted with
the <R>emove command (Section III - 3.16).
44..1177 CCTTRRLL--WW ------ WWoorrkkiinngg mmeemmoorryy ssttaattuuss
<CTRL-W> is used to find out how much memory you have left in your
system, the current drive of the file being edited, or the current path
of the file. When this key is pressed, the information will be
displayed on the command line at the top of the screen. To return to
normal editing, simply press any key.
44..1188 CCTTRRLL--XX ------ EExxeeccuuttee tthhee rreeppllaacceemmeenntt ffrroomm aa sseeaarrcchh
When the system finds a match of the search string in the SEARCH
command, pressing <CTRL-X> will replace the string found with the
replacement string which was given to the prompt:
REPLACE STRING:
After the replacement is executed, the system will begin another search
for another occurrance of the search string.
44..1199 CCTTRRLL--YY ------ YYaannkk ((ppuutt)) ssttoorreedd lliinnee
<CTRL-Y> will get the line in the temporary storage area (saved with
the <CTRL-G> command) and place it immediately before the line where
the cursor is sitting.
44..2200 CCTTRRLL--ZZ ------ ZZaapp ttoo eenndd ooff lliinnee
This command deletes all the characters on the line where the cursor
lies from the cursor position to the end of the line including the
character under the cursor.
- 22 -
44..2211 SSHHIIFFTT--RREETTUURRNN ------ BBrreeaakk aa lliinnee
By pressing the <SHIFT> key and the <RETURN> key at the same time, you
can make DR-EDIT take all the characters to the right of the cursor
(including the character under the cursor) and put them on a new line
immediately following the line where the cursor is currently sitting.

_VV_.._ _ _MM_AA_CC_RR_OO_ _CC_OO_MM_MM_AA_NN_DD_SS
DR-EDIT has included the ability to combine several commands into a
single command called a "macro command". These specialized commands
are very useful and can increase productivity and efficiency greatly.
You can have up to ten different macros defined at one time. Each
macro is associated with one of the function keys on the keyboard.
That is, pressing the <F1> key will perform macro #1, <F2> will perform
macro #2, etc.
Building a macro command is as easy as performing the editing process
that you want the macro to be.
To start the building process, press the function key that you want to
define. A function key counter will appear at the far right of the
command line. Each time a key is pressed, it is added to the macro
being built and the key counter is incremented.
To stop the building process, again press the function key that you are
defining. DR-EDIT will save the new macro into the file:
DREDIT.FNC
which will be stored on the currently logged disk drive in the root
directory.
At this point, every time you press this function key that you have
just defined, the macro will be executed.
To clear the macro from memory, you may simultaneously press the
<SHIFT> key and the function key that you want to clear.

Below is a list of some special keys that are used by the DR-EDIT
system. Some of these keys are duplications of regular commands which
will significantly increase your productivity in your editing task.
The keys that are used may vary depending on the type of system you
have. This list is divided into two specific brands of computers.
Please note that when the items enclosed in `<>' are actual keys that
are pressed to activate the function or command. Items that are
displayed with the <CTRL-xxx> or <SHIFT-xxx> conotation mean that you
are supposed to press the <CTRL> key or <SHIFT> key and the other key
referenced at the same time. Please note that the TI-PC keys will also
work on the IBM-PC (ie. <SHIFT-HOME> is the same as <END>).

D-R Software has worked very hard to deliver a product that we feel is
a very useful tool and one that you will find enjoyable to use. It has
been used quite extensively in production environments and has been met
with alot of praise. However, we realize that this editor cannot be
all things to all people. We also realize that a problem with the
editor might arise from time to time (We are only human!). It is for
this reason that we welcome any suggestions that you might have to make
DR-EDIT a better product or any problems that you may encounter. We
have created the following report for you to communicate the nature of
your suggestions or problems. D-R Software cannot promise that all

Program Title: DR-EDIT version 1.0
PC-SIG Version 1
Tired of clumsy program editing tools? With DR-EDIT, program editing is
like wordprocessing. DR-EDIT emulates many common word processor and editor
features and is recommended for computer users with at least a moderate
technical knowledge of small computers and their programming. Given those
qualifications and one to two hours of practice, you can be up and running.
DR-EDIT can create or edit ASCII files and offers "horizontal
scrolling" to extend the screen's usable width from 80 characters to 32K.
It has an overall length limit of 9,999 lines (this version is limited to
200 lines), the ability to concurrently edit two files, and a macro
capability to expedite routine or repeated manipulations. A special
algorithm is used which makes DR-EDIT especially useful with artificial
intelligence languages such as LISP, PROLOG, and C.
Usage: Programming Editor
System Requirements: 128K memory, one floppy disk drive, and a printer
(optional).
How to Start: Type DREDIT (press enter).
Suggested Registration: $30.00
File Descriptions:
DREDIT DOC Documentation (26 pages).
DREDIT EXE Main program file.
DREDIT TI Adaptations for TI systems.
DREDIT IBM Adaptations for IBM systems.
