2.0 TEXT EDITORS and WORD PROCESSORS DEFINED
2.1 What Is A Text Editor?
A text editor is a program which will allow the user
the ability to enter text, move it around and a perform
a wide variety of text editing features. The two basic
types of text editors are line editors, such as EDLIN
which comes with IBM DOS, and full screen editors such
as SCREEN. The advantage of a full screen editor
over a line editor are many, the greatest is its ease
of use over a line editor. A full screen editor can
only be used with a CRT or monitor, but allows the
cursor, the tiny underline character which moves around
on the screen, to be moved to any position in your text
for character insertion, deletion and other editing
activities.
2.2 What Is A Word Processor?
A word processor is like a text editor in that you can
enter, delete and move the text around, but it also
formats the text in a specific way to be printed. This
manual is an example of text which has been processed
through a word processor. Word processors come in
three basic types. The first would be a line editor
like EDLIN used in conjunction with a text formatter.
(A text formatter is a program which reads a text file
and formats the text for a printer.) The next type of
word processor would be a full screen editor like
SCREEN used in conjunction with a text formatter.
The last and most popular type is that of a full screen
word processor like WORDSTAR(tm) which is a single
program which has both the full screen text editing
capabilities along with the text formatting
capabilities.
(c) 1983 by Basic Business Software, Inc. and Peter M. Burke
SCREEN - A Full Screen Text Editor Page: 10
2.3 Text Editor vs Word Processor, Which Do I Want?
The major advantage of a all in one word processor over
a text editor/formatter combination is that the all in
one word processor is easier to use. The main
disadvantage of a all in one word processor is that
many word processors insert formatting characters into
the text which will usually cause problems when you
want to use the word processer for editing say PASCAL
program file. A PASCAL, BASIC, FORTRAN or other type
of compiler will not like the formatting characters
that some word processors insert into the text. For
this reason alone many people like a full screen text
editor for editing program source code, and any
documents which do not need to be formatted in a
special way. The SCREEN editor has many features not
found in many word processors or other editors.

3.0 SETTING UP THE IBM PERSONAL COMPUTER SYSTEM
3.1 Getting SCREEN To Run
To bring up your IBM Personal Computer System so that
you can begin to use SCREEN text editor you should do
the following:
1) Insert your IBM DOS diskette into drive A:
2) Turn on your IBM Personal Computer
You should see the following on your screen:
DATE 01-01-1980
enter the date:
TIME 00:00:00.00
enter the time:
A>
When the computer asked for the date and time you
should enter the current date and time and strike the
ENTER key after you have entered each.
3) Now remove the DOS diskette from drive A:, and
insert into that drive the diskette which contains
SCREEN. Now type in the following:
A>SCREEN
Your computer will now start running the SCREEN text
editing system. You will see displayed on your monitor
the following:
Basic Business Software, Inc. SCREEN - A Full Screen Text Editor
IBM Personal Computer System (c) 1983 version [2.1]
Todays Date: AUG-29-1983 Current Time: 09:43:27
Enter The Filename.ext or [F1] for directory > <
At this time you should enter a filename.ext of any
file that you would like to edit. You may specify a
disk drive other than the default disk drive if
desired.
(c) 1983 by Basic Business Software, Inc. and Peter M. Burke
SCREEN - A Full Screen Text Editor Page: 12
NOTE: If you are using a one drive system, and do not
want to save the text on same disk which contains
SCREEN, then at this time remove the SCREEN disk
from drive A:, and insert the disk which contains the
file you want to edit, or the disk which will contain a
new file which is to be created with SCREEN.
Some valid example filename are:
HELLO.TXT
B:MENU.BAS
HELP
No filename may have an extension of .BAK, and do not
try to edit a filename of SCREENX.TMP, as this name
is used by the text editor.
If no extension is given an extension of .BAS will be
assumed for that file. The filename which you entered
will be looked for on the disk, if it is found SCREEN
will load in as much of the text as will fit into
memory, and will display the first twenty-three lines
on the screen and allow you to begin editing the text.
If the filename.ext was not found the following will
appear on your monitor:
Do You Want To Create This File (Y/N) ?> <
To this question you must enter a Y or N. If you
enter a Y, a file with that name will be created on
the disk, and text editing can now begin. If you enter
^N^ to the question no file will be created, and you
will again be asked to enter the filename.ext of a file
to edit.
If you decide you do not want to edit any file, strike
the ENTER key for the filename, and SCREEN will
end, and you will be returned to the disk operating
system.
Please note that if you are not sure of the
filename.ext which you wanted to use, you can enter in
the word DIR or dir. This will bring up a directory
display of a disk on your monitor. Please note that
instead of typing in the word DIR, you could strike
the function key F1 to get a disk directory display.
The computer will now ask:
Enter disk drive device > <
(c) 1983 by Basic Business Software, Inc. and Peter M. Burke
SCREEN - A Full Screen Text Editor Page: 13
To this you can strike the ENTER key, which will
cause the current disk to be used, or you can enter a
letter A,B,C,D,E, or F for the drive which you want
to get a directory of. The computer will next ask:
Enter the filename extension: > <
To this you can strike the ENTER key, which will
cause all files to be displayed. You could also enter
a one to three character extension, which would cause
only the filenames with that extension to be displayed
on you monitor. After all filenames have been
displayed you will see:
Please Strike The ENTER Key To Continue ...
At this time you must strike any key which will display
back on the monitor the prompt which will ask you to
enter the filename of the file which you want to edit
with SCREEN.

3.2 How To Load The Microsoft Mouse Software Driver
The Microsoft Mouse may be used with this editor to
position the cursor on the screen, and also to select
the options from the FUNCTION LINE of the editor. To
use the this mouse you must have a the Microsoft Mouse
software driver loaded into the computer memory. The
program which does this is called MOUSE.COM which is
provided by Microsoft with each mouse. To copy this
file to the SCREEN diskette do the following:
1) Insert your SCREEN diskette into drive A:
2) Insert the disk which came with your Microsoft Mouse
into drive B:
3) Type in the following:
A:MMOUSE
The program MOUSE.COM should now be on your SCREEN
diskette and you need to type in the following each
time you reset your computer before you use the SCREEN
text editor:
MOUSE
You should see the message 'mouse driver loaded'.
Remember you only need to load the mouse driver once
after the computer has been rebooted. After the mouse
driver has been loaded into memory you can use the
SCREEN editor with the same commands as without out the
mouse, but you know have the ability to use the mouse
for special cursor positioning functions as well.
(c) 1983 by Basic Business Software, Inc. and Peter M. Burke
SCREEN - A Full Screen Text Editor Page: 15
3.3 How To Use The Microsoft Mouse
The Microsoft Mouse will allow the user the ability to
position the cursor by moving the mouse around, and the
mouse is also used to select a selection from the
FUNCTION LINE.
The mouse can be positioned anywhere in the text by
holding down the left button of the mouse while you
move the mouse in the direction that you want to move
the cursor. One you have positioned the cursor to the
point in the text which you want to be, you should let
up on the left button. You can position the cursor
with either or both, the mouse and the arrow keys.
Pressing both of the keys of the mouse at the same
time, is the same as striking the ESCape key. This
makes it easy to go into and exit from the function
line. Once you are in the function line you can select
a given function by holing down the left button and
moving the mouse to the right or left until the
selection that you desire is displayed in normal video.
To select that function push the right button. Pushing
this button is the same as striking the RETURN key.
When the mouse is being used to move the cursor you
will see in the right hand corner of the STATUS LINE a
arrow which is pointing one of four directions. It
will be pointing in the direction that the mouse last
moved. If you push the right button on the mouse, one
of the following actions will be taken:
If the arrow is pointing to the RIGHT, the action will
be the same as striking the END key, which will position
the cursor to the end of the current line.
If the arrow is pointing to the LEFT, the action will
be the same as striking a control-B key, which will
position the cursor to the beginning of the current
line.
If the arrow is pointing UP, the action will be the
same as striking the PgUp key, which will display on
your monitor the previous page of text.
If the arrow is pointing DOWN, the action will be the
same as striking the PgDn key, which will display on
your monitor the next page of text in your file.

3.4 How The Backup Text File Is Created
Every time you edit a file with the SCREEN editor a
file with the same name, but an extension of .BAK is
created which is a copy of your text file before you
begin to edit it with SCREEN. This will allow you
the ability to recover your file in case you did
editing on a file that you did not want to do. This
file will be created on the same disk that your text
file is located on.

4.0 TEXT EDITING
4.1 Editing With SCREEN
This section of the manual will explain how editing of
text can be performed with the SCREEN text editor.
Each of the editing functions will be explained as to
its function and use. To being a practice editing
session, type in the following:
A>SCREEN
Enter Your Filename.ext or [F1] for directory: >SAMPLE.TXT<
The computer will now display the first twenty-three
lines of the file SAMPLE.TXT on your monitor, and the
cursor will be located in the upper left hand corner of
the screen. You can use this file to demonstrate the
various editing capabilities of the SCREEN editor.
4.2 The Ruler Guide
The ruler guide is the line of numbers and dots which
you will see displayed in high intensity and underlined
at the very top of your monitor. It is a guide to show
you the position of your cursor on a line. The ruler
should look something like:
....+....1....+....2....+....3....+....4....+....5....
The 1,2,3,4 and onward represent the tenth, twentieth,
thirtieth and onward character position. The symbol
that looks like a diamond represents the half way point
between each set of ten character postions. The ruler
will always display seventy-nine positions across at
the top of the screen.
4.3 The Pointer
The pointer is a downward pointing arrow which moves
along the ruler guide to show you exactly what
character position the cursor is currently located at.
(c) 1983 by Basic Business Software, Inc. and Peter M. Burke
SCREEN - A Full Screen Text Editor Page: 18
4.4 The Line Length
The length of any single line of text can be from one
to two-hundred and fourty characters long. When you
type past the seventy-ninth position on the screen, the
screen will move over the text so that you can see the
next fourty character positions. As you move through
the text the ruler guide will change to reflect the
current character position.
4.5 The Page Length
The length of a single page of text is twenty-three
lines of text. This is the number of lines of text
which can be displayed on your monitor at one time.
This editor has the ability to hold fourty-four pages
of text in memory at one time.
4.6 The Text Length
The maximum number of lines of text which can be edited
at any one time is 999 lines. Most text files will not
be this long. If your text file is longer than this,
you will edit portions at a time. The SCREEN editor
has facilities to read and write to and from the disk
portions of your file.
4.7 The Memory Size
The maximum size of any text file which can be loaded
into memory at any one time is about 50,000 bytes.
The SCREEN editor requires a minimum amount of 128K
bytes of memory to operate correctly. At this memory
size you can edit a file of over 45,000 bytes in
memory at once using DOS 1.1 or about 33,000 bytes in
memory if you are using DOS 2.0. If you have 196K
bytes of system memory you can edit a file of about
50,000 bytes which is the maximum allowed by SCREEN.
Even if you have more than 196K bytes of system
memory, the 50,000 bytes is the maximum
text file size allowed in memory at one time. SCREEN

that is the most which can be in memory at one time.

5.0 THE IBM PERSONAL COMPUTER KEYBOARD
5.1 Which Keys Are Used With SCREEN ?
Your IBM Personal Computer has a very nice keyboard,
with many special function keys which can be used with
this text editor. The special keys which you should
become familiar are:
5.2 What Are The FUNCTION Keys ?
The function keys are the ten keys which are located on
the far left hand side of your keyboard, they are
labeled F1 though F10. Each one of these function
keys will perform a special function with the SCREEN
editor. The SCREEN editor comes with an overlay for
the function keys, which will allow you to use these
keys without having to lookup their functions in the
manual. The functions are listed below, but at this
time at you do not need to know what each of these
means:
F1 - insert a line F2 - delete a line
F3 - search for text F4 - replace text
F5 - search next F6 - erase text
F7 - set begin marker F8 - set end marker
F9 - center line F10- help menus
5.3 What Is The ESCAPE Key ?
The ESCAPE key is located on the upper left hand
corner of your keyboard, is one of the single most
important keys which will be used with SCREEN. The
escape key which is labeled ESC will allow you into
most editing features of SCREEN, and will get you out
of any editing features which you may decide to exit
from. This use of this key is explained in detail
later in this manual.
5.4 WHat Is The ENTER Key ?
The ENTER key is the oblong key on the right side of
the keyboard, it is also known as the RETURN key or
CARRIAGE RETURN key. It will be used in many
instances to enter your responce into the editor.

SCREEN - A Full Screen Text Editor Page: 20
5.5 What Is The TAB Key ?
The TAB key which is located on the upper left hand
side of the keyboard above the CTRL key, will move
the cursor over to the next tab stop. Tab stops are
preset at every five character positions, and cannot be
changed.
5.6 What Is The CONTROL Key ?
A CONTROL key is any key which is struck while the
control key is held down at the same time. As an
example a control S would entered by holding down the
CONTROL key and then striking the S key. The control
key is on the lower left hand side of the keyboard and
is labeled CTRL. Many Word processors and text
editors make extensive use of control keys, for ease of
use we have limited the number of control keys which
SCREEN will use to ten.
5.7 What Is The Text Editing Keypad ?
This is the cluster of keys which make up your 10-key
numeric keypad, and also doubles as your text editing
keys. The key labeled NUM-LOCK will allow this
keypad to be used as either the numeric keypad, or used
as the text editing keypad. We suggest you use it only
as the text editing keys, and use the number keys at
the top row above the normal alpha keys for numbers.
This will make it easier to use, in that you will not
have to keep using the NUM-LOCK key to switch back
and forth between using the keys as a numeric keypad
and text editing keys. The text editing keys available
are:
UP ARROW - located on the 8 key on the numeric
keypad. This will move the cursor up one line of text.
If the cursor is at the top line of the screen and the
up arrow is struck the text will be redisplayed with
that line now in the center of the screen.
DOWN ARROW - located on the 2 key on the
numeric keypad. This will move the cursor down one
line of text.
RIGHT ARROW - located on the 6 key on the
numeric keypad. This will move the cursor one
character position to the right.
(c) 1983 by Basic Business Software, Inc. and Peter M. Burke
SCREEN - A Full Screen Text Editor Page: 21
LEFT ARROW - located on the 4 key on the
numeric keypad. This will move the cursor one
character position to the left.
BACK ARROW - delete key which is located above
the return key on the keyboard. This key will delete
the character to the immediate left of the cursor.
HOME - located on the 7 key on the numeric
keypad. This will move the cursor to the upper left
hand corner of the screen.
PGUP - located on the 9 key on the numeric
keypad. This will move the cursor backward one page of
text, which is 23 lines of text.
PGDN - located on the 3 key on the numeric
keypad. This will move the cursor forward one page of
text, which is 23 lines of text.
END - located on the 1 key on the numeric
keypad. This will move the cursor to the end of the
line of text which the cursor is currently located on.
CONTROL LEFT ARROW - the control key must be
held down and strike the left arrow key at the same
time. This will move the cursor to the beginning of
the word on the immediate left of the cursor.
CONTROL RIGHT ARROW - the control key must be
held down and strike the right arrow key at the same
time. This will move the cursor to the beginning of
the word on the immediate right of the cursor.
CONTROL PGUP - the control key must be held
down and strike the pgup key at the same time. This
will move the cursor backward three pages of text,
which is sixty-nine lines of text.
CONTROL PGDN - the control key must be held
down and strike the pgdn key at the same time. This
will move the cursor forward three pages of text, which
is sixty-nine lines of text.
CONTROL HOME - the control key must be held
down and strike the home key at the same time. This
will move the cursor to the first character of the last
line on the currently displayed page of text.

SCREEN - A Full Screen Text Editor Page: 22
CONTROL END - the control key must be held down
and strike the end key at the same time. This will
erase all text on that line from the current cursor
position to the end of the line.
INS - the insert key is located on the 0 key on
the numeric keypad. When struck this will allow you to
insert text into the current line where the cursor is
located. This is a toggle key, you strike it once to
go into the insert mode, and strike it again to get out
of the insert mode. When in the insert mode the cursor
will become one half its normal size.
DEL - the delete key is located on the . key
on the numeric keypad. When struck the character that
the cursor is currently positioned over will be
deleted. The text on the right of the deleted
character will be moved over one character to the left.

11.0 THE MARKER FUNCTION
11.1 How To Mark A Block Of Text
The Marker function will allow you to mark the
beginning and ending line of a block of text, and it
will also allow you to clear and recall any previously
set markers. Markers are used to mark off a block of
text which will be manipulated by the BLOCK function.
A block consists of a group of one or more lines of
text which have had a beginning and ending marker set.
When you mark a group of lines of text they will be
displayed in high intensity on your monitor. You must
mark both a beginning and ending line of text before
you can use the BLOCK function on the block of text.
It is only possible to mark entire lines, and you
cannot mark only part of a line. To select the block
marker function strike the M key, you will then see
the following displayed on the bottom line of your
monitor:
==> < Beginning(unset) End(unset) Clear Recall (marker operations)
You can now select one of the following options:
Beginning - To set the beginning marker strike the
B key. The beginning marker will now be set for the
line that the cursor was last located at. You should
see that line appear in high intensity. After the word
beginning on the above line you will see the word set
or unset in parenthesis, this tells you if the marker
is currently set or not. Function key F7 will set a
beginning marker for you when struck.
End - To set the end marker strike the E key. The
end marker will now be set for the that the cursor was
last located at. You now should see all the lines of
text between the line the beginning marker was set on,
and the line of text the end maker was set on,
displayed in high intensity. After the word end on the
above line you will see the word set or unset in
parenthesis, this tells you if the marker is currently
set or not. Function key F8 will set a end marker
for you when struck.
Clear - To clear any markers which are currently set
strike the C key. This will clear any marker and
make them unset, and will redisplay any previously
marked block in normal intensity.

SCREEN - A Full Screen Text Editor Page: 38
Recall - To recall any markers which have been
previously set and then cleared strike the R key.
This will recall the last set of markers which were in

current editing session, then no markers will be
recalled.

12.0 THE BLOCK FUNCTION
12.1 How To Manipulate A Block Of Text
The Block function will allow you to move, delete or
copy a block of text which has been marked, with the
marker function, to another location in the text. The
block function will also convert a marked block to all
upper or lower case, and the block function can write
the marked block out to the disk, or read in a file
from the disk. Before any block operation, except for
reading in from the disk, can be performed on a block
of text, it must have been previously marked with the
marker function. To select the BLOCK function strike
the B key, you should see the following on the bottom
line of your monitor:
==> < Move Copy Delete Upper Lower Read Write (text block operations)
You now may select one of the following operations:
Move - To select the Move operation strike the M
key. The move operation will move the marked block of
text to the line that the cursor was last located at.
Make sure that after you mark the block of text which
is to be moved, and to position the cursor to the
correct line that you want the block of text moved to.
Copy - To select the Copy operation strike the C
key. The copy operation will copy the marked block of
text to the line that the cursor was last located at.
Make sure that after you mark the block of text which
is to be copied, to position the cursor to the correct
line that you want the block of text copied to.
NOTE: The difference between move and copy is that
the copy operation will make a duplicate of the marked
block of text in another location within your text.
The move operation actually moves the marked block of
text, and after the move operation is complete the
marked block of text will no longer be where it was
before the move operation.
Upper - To select the Upper operation strike the U
key. The upper operation will convert all characters
within the marked block of text to upper case.

on the bottom line of your monitor:
BLOCK READ: enter filename > <

followed by a colon.(i.e. A:TEXT.TXT). After you type
in the filename, strike the ENTER key, this will
cause the file to be read in from the disk and inserted
into your text. If the filename.ext was not found a
message will be displayed on the bottom of your
monitor. If the file was too large to fit into the
available memory, a message will be displayed on the
bottom of your monitor. Remember that the file read in
must be a text type file. The maximum size of a file
which can be read in with the block read function is
200 lines of text.
Write - To select the Write operation strike the W
key. The write operation will allow you to write to a
file on the disk a marked block of text. After you
select write, the following will be displayed on the
bottom line of your monitor:
BLOCK WRITE: enter filename > <
You should now enter the filename.ext of the file that
you want the marked block of text to be written to.
The file will be assumed to be located on the default
disk drive, but you can precede the filename.ext with a
drive letter followed by a colon.(i.e. B:TEXT.TXT).
After you type in the filename, strike the ENTER key,
this will cause the text to be written to the disk. If

19.1 Control Codes
There are ten 'control keys' which can be used with
this text editor to perform various functions. A
control key is activitated by striking the indicated
key while also holding down the CONTROL key at the
same time. Although we have tried to minimize the use
of control keys because they tend to be confusing to
use, we have limited our use to ten. The following
functions are provided:
19.2 Move The Cursor To The Beginning Of The Line
Control-B will move the cursor to the beginning of
the current line of text. If the cursor is past the
79th column the current page of text will be redispled
starting with column one.
19.3 Concataniate This And The Next Line
Control-C will concatinate the line cursor is
currently located on with the following line. This

Control-D will shift the entire page of text down one
line, but will leave the cursor positioned at the same
place on your monitor.
19.5 Exchange This Line With The Next Line
Control-E will exchange the current line of text with
the line below it. This function will leave the cursor
on the line below the current line. By using this
function several times you can move a line down several
lines in the text without using the block move
function. This function will not work if you are at
the end of the file, or are at the bottom line of your
monitor.

20.0 ERROR MESSAGES
20.1 Error Messages Which Can Appear In SCREEN
During the use of SCREEN a variety of messages can
appear on your screen, some of which are:
Disk is fill - exit the program now
If the above message appear it means that your diskette
is full and your text cannot be written out to that
disk. When this or any error message appears which has
to do with the disk drive, do the following:
(a) If full delete a file from that disk with the
Kill function in the Files selection.
(b) Go to the very first line of the text, use the
Locate function to do this, and set the beginning
marker. The go to the end of text, use the Locate
function to do this, and set the end marker. You can
use the function key F7 to set the beginning marker,
and the function key F8 to set the end marker.
(c) Select Block from the selection line and select
the Write function to write out the text to disk.
Enter a filename other than the filename which you are
currently editing. After this has been done you will
have a copy of all the text in memory on the disk.
(d) You should now exit out of the program by selecting
the Files function from the selection line and then
select Quit to exit the program
The above proceedure should be completed for any of the
following messages:
Too many files on disk - erase some files
Bad filename was used
Disk is write protected
Disk drive is not ready
Disk media error - use different disk
Remember after any of the above errors the normal
finish or save command cannot be used.
(c) 1983 by Basic Business Software, Inc. and Peter M. Burke
SCREEN - A Full Screen Text Editor Page: 53
If your memory falls below 800 bytes free you will see
the following message on your screen:
out of memory
out of string space
memory space error
At this time you should exit the program by saving your
text to the disk with the Save or Finish function.
It would be a good idea not to let the memory available
fall below 2000 bytes. You can free up additional
memory by using the Files function with the Write
command.
If the amount of free memory falls too low the program
will automatically delete the last two lines of your
text so that it can free up enough memory to perform a
Save or Finish. If it does this, a message will
appear on your screen.
If any other type of error message appears it will look
like the following:
SCREEN error number: ##
The ## will be some number between 01 and 99, if this
message should appear contact Basic Business Software,
Inc. for help.
