>a3:"                         TEACH ME PERFECT CALC
>a5:"       Welcome to Perfect Calc, the revolutionary new electronic
>a6:" spreadsheet from Perfect Software.
>a8:"       This begins a series of short 'software based' lessons to
>a9:" acquaint you with Perfect Calc.  You will be working at the
>a10:" computer, following directions displayed on the screen.  The first
>a11:" command we will introduce is the PAGE DOWN Command, which you
>a12:" will use to scroll the screen in order to continue reading your
>a13:" instructions:
>a14:"                          Control---v
>a16:"       This command is executed by holding down the 'Control' key
>a17:" (labeled 'CTRL') and typing the lowercase letter 'v'.
>a19:"       At this time go to the next page of these instructions 
>a20:" using this command.
>a24:"       In the same way previous pages or screen of text can be viewed
>a25:" using the PAGE UP Command:
>a26:"                               Control---z
>a28:"       (While depressing the Control Key, type a lowercase 'z'.)
>a30:"       These two commands will enable you to scroll through these 
>a31:" instructions as you wish, either bringing new text into view, or
>a32:" recalling past sections for review.  For a few seconds practice
>a33:" scrolling the screen up and down.  When you have finished return 
>a34:" to this point.
>a37:" OVERVIEW
>a39:"       Several years ago the simple pocket calculator changed the
>a40:" way people everywhere dealt with numbers.  No longer were numbers
>a41:" added, subtracted, or multiplied using pencil and paper, or even
>a42:" mechanical adding machines.  Numerical data began being manipulated
>a43:" electronically, resulting in greater speed, accuracy, and 
>a44:" efficiency.
>a46:"       Today an innovation even more important than the pocket 
>a47:" calculator has emerged--the electronic spreadsheet, which represents
>a48:" nothing less than a revolution for mathematical computation and
>a49:" financial analysis.  No longer does the effective understanding
>a50:" and use of numerical data (financial, statistical, or scientific) 
>a51:" require sophisticated mathematical training.  For the first time
>a52:" you can quickly and efficiently apply sophisticated mathematical
>a53:" analysis to your financial and scientific affairs.
>a55:"       But if spreadsheets represent a 'revolution', Perfect Calc
>a56:" represents yet another revolution.  Designed to make your work with
>a57:" numbers simpler, easier, more enjoyable and more productive than
>a58:" ever before, it represents the most advanced, powerful, and
>a59:" versatile electronic spreadsheet available today.
>a61:"       The following lessons will show you just how easy Perfect
>a62:" Calc is to use.  Before you are finished, you will agree that 
>a63:" learning Perfect Calc is no more difficult than was learning to
>a64:" use a hand calculator.
>a68:"       More than this, you will be amazed at how greatly Perfect
>a69:" Calc eases the burden of mathematical computation and financial 
>a70:" analysis, thus expanding your capabilities, allowing you to do
>a71:" things you never dreamed possible.  If you are a scientist, 
>a72:" Perfect Calc will make your research more productive; if you are
>a73:" a business person, Perfect Calc will expand your grasp of financial
>a74:" matters;  if a student, get ready for the honor roll!  Again, 
>a75:" welcome to Perfect Calc, the 'next step' in electronic spreadsheet
>a76:" calculating!
>a78:"  BEGINNING
>a80:"       As you can see, this text has been entered on a Perfect 
>a81:" Calc spreadsheet.  On the left-hand side and top of the screen
>a82:" appear numbers and alphabetic characters, identifying the lines and
>a83:" columns.  The spreadsheet, which is a matrix of intersecting lines
>a84:" and columns, is much larger than what actually appears on the screen.
>a85:" It extends down 255 lines, and off-screen to the right 52 columns.
>a86:" The first 26 columns are labeled 'a - z' and the second 26 'A - Z',
>a87:" while the lines are numbered 1 to 255.
>a89:"       Each intersecting line and column marks an 'entry position', 
>a90:" capable of holding a label, number, or formula.  Every entry position
>a91:" is identified by a pair of 'coordinates'--i.e. the letter and 
>a92:" number of the column and line which intersect to form the entry
>a93:" position.  For example, 'b2' specifies the entry position formed by
>a94:" the intersection of column 'b' and line '2'.
>a96:"       The 'Cursor' marks the position on the spreadsheet where data
>a97:" is being entered.  The cursor on line 89 appears as a pair of facing
>a98:" 'angle-brackets, <  > , enclosing the entry position it occupies.
>a100:"       At the bottom of the screen is the 'Prompt Line', a partially
>a101:" blank line in which all data is displayed prior to being entered into
>a102:" the spreadsheet.  In addition, when Perfect Calc requires information
>a103:" from you, it will display an appropriate command message in this line.
>a105:"       At the right side of the Prompt Line certain information is
>a106:" displayed:  1)  The name of the spreadsheet 'buffer' currently being
>a107:" viewed (teachme);   2) a star,  *  , the presence of which tells you
>a108:" that the current spreadsheet has NOT been saved since last being 
>a109:" modified;  and 3)  the coordinates marking the current position
>a110:" of the cursor in the spreadsheet (a89).
>a112:"  COMMAND KEYS
>a114:"       Perfect Calc employs three types of commands (Users familiar
>a115:" with Perfect Writer will recognize them immediately!):
>a117:"    -  CONTROL Commands:  These commands utilize the 'Control' Key,
>a118:" requiring that the Control Key be DEPRESSED  and HELD while typing 
>a119:" the second character of the command.  The PAGE UP and PAGE DOWN 
>a120:" Commands, which we learned at the beginning of this lesson, are 
>a121:" examples of control commands.
>a123:"   -  ESCAPE Commands:  These commands utilize the 'Escape' Key (label-
>a124:" led 'ESC').  Unlike the Control Key, the Escape key need not be held.
>a125:" It has only to be depressed and then released, followed afterwards by
>a126:" whatever key completes the command.
>a128:"    -  EXTENDED Commands:  These commands are executed by typing the 
>a129:" Control Key together with a lowercase 'x', followed after by another
>a130:" character to complete the command.  'Extended' commands are similar to
>a131:" Escape Commands, in that once 'Control--X' has been typed, the keys
>a132:" can be released.  The next character typed completes the command.
>a134:" The 'software based' lessons included in this series are:
>a136:"   Teachme.pc       An Introduction to the Lessons
>a137:"   Lesson1.pc       Moving Around the Spreadsheet
>a138:"   Lesson2.pc       Entering Data
>a139:"   Lesson3.pc       Storing & Printing Your Spreadsheet
>a140:"   Lesson4.pc       Replicating Formulas, Inserting, Deleting & Moving
>a141:"   Lesson5.pc       Copying Between Spreadsheets
>a142:"   Lesson6.pc       Setting Up the Spreadsheet As You Like It
>a143:"   Lesson7.pc       Using Associated Files
>a144:"   Lesson8.pc       Concluding Suggestions
>a146:"       These lessons roughly approximate the organization of Perfect
>a147:" Calc's User's Guide.  Though they attempt to illustrate every major
>a148:" command procedure, you will nevertheless want to consult the User's
>a149:" Guide for more detailed discussions and examples.
>a151:"       Throughout the lessons the screen will be divided into two 
>a152:" 'windows'.  The top window will display a sample spreadsheet, while
>a153:" the bottom window will display the instructions you will follow.
>a154:" Let us now create two windows to see exactly how this will work.      
>a155:" Move the cursor down to line 165 in the middle of the screen using the
>a156:" 'down arrow' key, or the NEXT LINE Command:
>a157:"                        Control---n
>a158:"       Next, type the CREATE TWO WINDOWS Command:
>a159:"                      Control---x  2
>a160:" (While depressing the Control key, type 'x'; releasing these, type '2')
>a161:"       Perfect Calc responds with the message:  "Synchronize windows?"
>a162:"       Answer 'n' for no.
>a163:"       ('Synchronization' causes the windows to move in unison whenever
>a164:" one or the other is scrolled, a function we will not need here.)
>a165:"   Perfect Calc immediately splits the screen into two windows, with the
>a166:" cursor in the bottom window.  Though both windows are now looking at 
>a167:" portions of the same text, the windows can be moved independently.
>a168:"       However, Control---v and Control---z will scroll ONLY the window 
>a169:" which the cursor is occupying.  Try this now, returning to this point.
>a171:"       Throughout the lessons the top window will hold a sample spread-
>a172:" sheet for you to work with, while the bottom window will contain the
>a173:" instructions you are to follow.  It will be necessary  to scroll the
>a174:" bottom window to continue reading the instructions. 
>a175:" Perfect Calc provides two commands for scrolling the 'other window':
>a176:"     Control---x  Control---v       PAGE DOWN 'Other Window'  Command  
>a177:"     Control---x  Control---z       PAGE UP "Other Window' Command
>a178:"  (While depressing the Control Key, type 'x' and then 'v' or 'z')
>a179:"       Notice that these two commands differ from the regular Page 
>a180:" commands only in that they contain the 'extended' command prefix
>a181:" 'Control---x'.  At this time practice scrolling the top window using
>a182:" using these two commands.  Find this line (182) in the top window. For
>a183:" the next few pages read the instructions displayed in the TOP window
>a184:" using Control---x Control---v, keeping the cursor in the bottom window.
>a185:" The HELP MENU
>a186:"       Perfect Calc provides a screen displayed Help Menu which lists
>a187:" all system commands available to you.  To display this Help Menu type a
>a188:" a question mark (  ?  ) at any time while working on the spreadsheet.
>a189:"      Do this now-- type a '?'   The Help Menu will display at the
>a190:" bottom of the screen, overwriting whatever data is being displayed. 
>a191:"       As you can see, the Help Menu lists the commands by category,
>a192:" which can be selected by typing a number followed by the 'Return' key.
>a193:" For example, to see commands on 'Moving the screen', type '2' and press
>a194:" 'Enter'.  Perfect Calc lists the screen commands.  Are some familiar?
>a195:"       Type a second question mark  (  ?  ).  The original menu is 
>a196:" redisplayed.  As you might guess, it is possible to learn a good bit
>a197:" about Perfect Calc by simply browsing the Help Menu.  Do this now
>a198:" to see the variety of command procedures that are available to you.
>a199:"     To erase the Help Menu, type any command which causes the window
>a200:" containing the Help Menu to be redrawn--in this case, the PAGE DOWN
>a201:" Command  (Control--v).
>a202:"    The window which the cursor is occupying can be redrawn using the
>a203:" REDRAW WINDOW COMMAND:  Escape...Control---L   (Press and release the 
>a204:" Escape Key;  then, while holding the Control key, press 'L'.)
>a205:"       Move the cursor to the top window you've been reading from by 
>a206:" typing the switch to OTHER WINDOW Command:
>a207:"          Control---X  o    ælowercase "letter" 'o'å
>a208:"   Note that, as has been indicated throughout these instructions,
>a209:" ALL of Perfect Calc's commands USE LOWERCASE LETTERS!
>a211:"       Return to a single window now by typing the CREATE ONE WINDOW
>a212:" Command:     Control---x  1
>a213:" Perfect Calc makes the window holding the cursor the only window on 
>a214:" the screen.
>a217:"  The CANCEL or Go Back Command
>a219:"       One useful command to know right away is the CANCEL Command.  
>a220:" Any command which Perfect Calc HAS NOT YET BEGUN EXECUTING can be 
>a221:" cancelled by typing:
>a222:"                       Control---g
>a224:"       Thus, if you change your mind about something and want to stop 
>a225:" and GO back, or if you simply get stuck, the Cancel Command will 
>a226:" return you to the spreadsheet.
>a227:"     At this time if you wish to begin the first lesson, first exit 
>a228:" Perfect Calc with the QUIT Command and then enter: 
>a230:"  A>pc b:lesson1.pc       æbe sure to include the drive location
>a231:"    ^       ^                       for the fileå 
>a232:" program   filename
>a233:"   name
>a235:"  'pc' is the program name which tells your computer's operating system
>a236:" to execute Perfect Calc.  'b:lesson1.pc' is the name of the file you 
>a237:" want to use with Perfect Calc.
>a239:"  To exit Perfect Calc, use the QUIT Command:
>a241:"                   Control---x  Control---c
>a243:"      Should Perfect Calc respond with the message "Ignore changes
>a244:" this session?", answer 'y' for yes.  Perfect Calc will return you 
>a245:" to your computer's operating system, where you may enter 
>a246:" "pc b:lesson1.pc"  to begin the first lesson.
>a248:"                    END OF INTRODUCTORY LESSON
