>a2:"              LESSON3 -- Storing & Printing Your Spreadsheet
>a5:"      Begin by moving the cursor to line 11 and enter the CREATE TWO
>a6:" WINDOWS Command:
>a8:"          Control--x  2  æanswer no to the 'Synchronize Windows' promptå
>a10:"  Retrieve a copy of the 'stockhex.pc' file and place it in the top
>a11:" window.  This requires you go to the Other Window using the OTHER
>a12:" WINDOW Command.
>a13:"                   Control--x  o (the letter 'o')
>a14:"    Then find the 'stockhex.pc' file with the FIND FILE Command
>a15:"              Control--x  Control--f
>a16:"   When Perfect Calc responds, "File to find <CR>: ", enter:
>a17:"'stockhex.pc' æRemember to give the disk drive the file is
>a18:"  located onå,  followed by a carriage return.
>a20:"  As before, scroll the bottow window with the 'Other Window' commands.
>a22:"     When you read a file from diskette into the computer's memory it
>a23:" is copied into a temporary work space called a 'buffer'.  While
>a24:" in the  memory buffer, the spreadsheet represents only 
>a25:" a 'copy' of the original spreadsheet which still remains on diskette.
>a26:" Any changes you make to the copy in the buffer does not affect the
>a27:" original version until you enter the SAVE FILE Command which then saves
>a28:" the file by writing it onto the diskette, a process which 
>a29:" OVERWRITES the original file with the modified version.
>a30:"
>a31:"       Perfect Calc provides two commands for storing your spreadsheet.
>a32:" The first is the SAVE FILE Command.  At anytime during spreadsheet
>a33:" editing type:
>a34:"                  Control--x  Control--s
>a35:"     Perfect Calc begins saving the spreadsheet to disk.  During this
>a36:" process it displays the message:  "Writing STOCKEX.PC..."
>a37:"       Perfect Calc copies the spreadsheet to disk, overwriting whatever
>a38:" original version of the spreadsheet was there before.  If used often, 
>a39:" the SAVE FILE Command guards against accidental losses of new data
>a40:" during long editing sessions.
>a41:"       The second command for storing a spreadsheet file is the WRITE
>a42:" FILE Command, which allows you to save a spreadsheet to disk under a
>a43:" DIFFERENT file name, thereby preserving the original version of the
>a44:" spreadsheet on disk under the original filename. (The result is two 
>a45:" files saved on disk--the original and the modified copy).  Let us 
>a46:" practice the WRITE FILE Command:
>a47:"                     Control--x  Control--w
>a48:"       Perfect Calc responds with the message:
>a49:"                       "Write to file: <CR>  "
>a50:"Type a new filename for the Stock Portfolio Spreadsheet, 'stocktwo.pc'
>a51:"       Perfect Calc writes the spreadsheet to disk under the new file
>a52:" name.  During this write operation the message is displayed:
>a53:"                  "Writing STOCKTWO.PC"                      
>a54:"       After the write operation is complete Perfect Calc returns you
>a55:" to the spreadsheet to continue working.  The spreadsheet now exists in
>a56:" in two file locations:  the old version, 'stockex.pc', and the newly 
>a57:" modified version, 'stocktwo.pc' .  The file you are working with is
>a58:" now called 'stocktwo.pc', and hereafter, should a SAVE FILE Command
>a59:" be given, Perfect Calc will overwrite the new version you have just 
>a60:" written to disk.
>a61:" PRINTING
>a62:"       Printing the spreadsheet is very simple, and can be performed
>a63:" at anytime during editing.  You can print either the entire spread-
>a64:" sheet, or any defined region of it.  Let us print 'stocktwo.pc' now. 
>a65:" Make sure your printer is turned on and properly attached.  If you have
>a66:" no printer, ignore the print commands.  Enter the PRINT Command:
>a67:"                Control--x  Control--p
>a68:"   Perfect Calc responds with the message:   "Print to file: <CR> "
>a69:"        Hit a carriage return.  Perfect Calc outputs the spreadsheet to
>a70:" your printer.  Perfect Calc prints by columns.  It will print the first
>a71:" 80 character-columns in their entirety before proceeding to print the
>a72:" second 80 character-columns.  For spreadsheets that are long (i.e.,
>a73:" have many lines), it may take several pages to print the first screen-
>a74:" ful of columns, before moving on to print the next group of columns.
>a76:"       Printing a 'region' of the spreadsheet is accomplished in
>a77:" exactly the same way, except that before executing the PRINT REGION
>a78:" Command, you must define the region to be printed.  Let us see how this
>a79:" works by printing the first column of our spreadsheet.  
>a81:"       Position the cursor at 'a1'.
>a82:"       Set a boundary mark using the MARK SET Command:
>a83:"             Escape...<space bar>  æthe long bar used for typing spaceså
>a84:"       Perfect Calc responds:  "Mark set at a1" .
>a85:"       Move the cursor to the bottom of the column using the BOTTOM OF
>a86:" COLUMN Command:
>a87:"                      Escape...>
>a89:" (The new position of the cursor marks the other boundary of the 
>a90:" region to be printed.)
>a92:"       Now, type the PRINT REGION Command:
>a94:"                      Control--x   p
>a96:"       When Perfect Calc responds "Print to file", type a carriage
>a97:" return.  Perfect Calc prints the defined region.
>a101:"  PRINTING TO 'PERFECT WRITER'
>a102:"       It is possible to print the spreadsheet, or any portion thereof,
>a103:" to disk as a 'screen image'.  This is unlike the form in which a file
>a104:" is stored using the WRITE FILE or SAVE FILE Commands.  Printing to
>a105:" disk is convenient  when you want to include your spreadsheet in a 
>a106:" report that you are preparing with Perfect Writer.  Execute the print
>a107:" commands as you would normally, except that when Perfect Calc presents
>a108:" the message "Print to file",  supply a file name that can later
>a109:" be accessed by Perfect Writer.  (Perfect Writer uses the suffix ".mss"
>a110:" on all its filenames. Thus, 'stocktwo.pc' will become 'stocktwo.mss'.)
>a111:"       This concludes the lesson on storing and printing your spread-
>a112:" sheet.  If you wish to continue to the next lesson which deals with
>a113:" replicating formulas, inserting, deleting, and moving, clear the
>a114:" entire memory and read in the "lesson4.pc" file.
>a116:"      The CLEAR ENTIRE MEMORY Command is:  Control--x  Control--k
>a118:"      The FIND FILE Command is:  Control--x  Control--f
>a120:"       If you do not wish to continue with the lessons, type the
>a121:" QUIT Command:
>a123:"                Control--x  Control--c
>a125:"     Answer 'y' for yes to Perfect Calc's question:  "Ignore changes 
>a126:" this session?"
>a128:"                      END OF LESSON 3
