Burke SCREEN - A Full Screen Text Editor Page: 9 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. (c) 1983 by Basic Business Software, Inc. and Peter M. Burke SCREEN - A Full Screen Text Editor Page: 11 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. (c) 1983 by Basic Business Software, Inc. and Peter M. Burke SCREEN - A Full Screen Text Editor Page: 14 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. (c) 1983 by Basic Business Software, Inc. and Peter M. Burke SCREEN - A Full Screen Text Editor Page: 16 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. (c) 1983 by Basic Business Software, Inc. and Peter M. Burke SCREEN - A Full Screen Text Editor Page: 17 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 has facilities to edit files much larger than that, but that is the most which can be in memory at one time. (c) 1983 by Basic Business Software, Inc. and Peter M. Burke SCREEN - A Full Screen Text Editor Page: 19 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. (c) 1983 by Basic Business Software, Inc. and Peter M. Burke 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. (c) 1983 by Basic Business Software, Inc. and Peter M. Burke 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. (c) 1983 by Basic Business Software, Inc. and Peter M. Burke SCREEN - A Full Screen Text Editor Page: 23 6.0 THE STATUS LINE 6.1 What Is The Status Line? The status line is the line which appears at the very bottom of your monitor in inverse video. It should look something like this: <^#> editing file:SAMPLE.TXT free:44,104 page:1 line: 1 col: 1 ^ Each of the items included in this status line is explained below. 6.2 What Are The Key Lock Indicator Symbols ?

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.
