>a3:"                      LESSON8 --  Concluding Suggestions
>a6:" TRUE ASCII DATA FILES
>a8:"       We have seen how Perfect Calc spreadsheet files can be included
>a9:" in documents and reports created by Perfect Writer.  It so happens that
>a10:" they can also be 'edited' by Perfect Writer, a feature made possible
>a11:" because both programs utilize true ASCII characters (the industry 
>a12:" standard for text files).
>a14:"       This is an extremely important feature, for it may sometime
>a15:" occur that a Perfect Calc data file will become 'damaged' .  For
>a16:" example, you may be attempting to save a Perfect Calc file to a disk 
>a17:" that does not have enough room to hold it, thereby causing a system
>a18:" error.  Thereafter any attempt to read even the original data file
>a19:" produces an error message, such as "Bad File--Read Aborted" .  Due to a
>a20:" slight internal code irregularity caused by the write error, Perfect
>a21:" Calc is now unable to interpret the file correctly.  
>a24:"       When something like this happens, do not despair.  The file is
>a25:" not lost.  Call the file into Perfect Writer and examine its lines for
>a26:" the cause of the difficulty.  Correct the error (usually one or more
>a27:" extraneous command characters which Perfect Calc does not recognize)
>a28:" and then transfer the file back to Perfect Calc, which should then be
>a29:" able to read it normally.
>a31:"       Perfect Calc files will not appear in Perfect Writer as the 
>a32:" 'screen image' that you are used to.  They will appear in the
>a33:" form in which they are actually stored as a Perfect Calc data file.
>a34:" Details for interpreting this format are provided in Appendix D of
>a35:" the Perfect Calc User's Guide.  Overall, it is an easy, convenient
>a36:" feature you will come to appreciate very much!
>a39:" USING PERFECT SPELLER WITH PERFECT CALC
>a41:"       In the same way, non-numeric data in Perfect Calc data files can
>a42:" be verified for correctness using Perfect Speller !  Again, this is
>a43:" possible because all Perfect Software programs utilize true ASCII
>a44:" characters.
>a46:"       If you are uncertain of the spelling of any function names,
>a47:" labels, or text which has been included in a Perfect Calc spreadsheet,
>a48:" call the file into Perfect Writer and invoke the Perfect Speller option
>a49:" as described in your Perfect Writer/Perfect Speller User's Guide.
>a50:" Perfect Speller will check for misspelled words, ignoring any of 
>a51:" Perfect Calc's numbers, formulas, and special command characters
>a52:" characters which may be imbedded in the file.
>a54:"       -- This is just one more refinement in a remarkable line of
>a55:" products available only from Perfect Software !
>a57:" 
>a58:" APPLICATION SPREADSHEET FILES
>a60:"      To get you started using Perfect Calc several pre-structured 
>a61:" spreadsheets have been provided.  You might begin by examining these
>a62:" and getting some ideas for what you want to do.  You can modify and
>a63:" change these to suit you particular needs.  Remember, these application
>a64:" files are for illustrative purposes only.  Perfect Software will not
>a65:" be able to help you with installing or customizing them.
>a67:" BUILDING A FUNCTIONS LIBRARY
>a69:"      One of the major features of the 'Associate Files' command is
>a70:" that it allows you to reference formulas in other spreadsheet buffers
>a71:" and use the results in the currently displayed buffer.  This feature
>a72:" provides you with the capability of building a file with formulas
>a73:" that you might use regularly and to name this file the 'functions
>a74:" library'.   To use this 'functions library' file all you need to do is
>a75:"  reference this file in your current buffer.  Since the 'functions
>a76:" library' is a standard spreadsheet file, you can easily add formulas
>a77:" and functions as needed.  It is possible to build function libraries
>a78:" for any number of specialized applications.  Thus, it is possible to
>a79:" have a library of insurance functions, engineering functions, and so
>a80:" on.  
>a82:"     When building a functions library you will want to experiment with
>a83:" creating a table of contents (with coordinate locations) for each of
>a84:" the formulas and functions contained in the file.
>a89:"       And so we conclude our lessons on Perfect Calc.  We regret that
>a90:" time and space limitation did not allow us to cover every aspect of
>a91:" the Perfect Calc system.  However, we hope that you have gained more
>a92:" than just a passing acquaintance with the power and versatility which
>a93:" Perfect Calc brings to electronic spreadsheet calculating, and that
>a94:" you are ready to begin making significant use of it in your business
>a95:" or profession.
>a97:"       The Perfect Calc User's Guide covers all of the topics we have
>a98:" mentioned here (plus a few others) in greater and more substantial
>a99:" detail.  It should certainly answer what remaining questions you may
>a100:" have.
>a102:"       Beyond that, we fully expect that you, as a soon-to-be
>a103:" 'expert' on Perfect Calc, will, before long, be showing US at Perfect
>a104:" Software aspects and applications of the system that even WE didn't 
>a105:" know existed !   Let us hear from you.  What you have to say is 
>a106:" important to us.  After all, we are here to serve you.
>a108:"                         END OF LESSON8
