- >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 {lowercase "letter" 'o'}
- >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 {be sure to include the drive location
- >a231:" ^ ^ for the file}
- >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
