>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 >a1 «eof»
