Editing Quattro Pro (section)

== Characteristics ==
Historically, Quattro Pro used keyboard commands close to those of [[Lotus 1-2-3]]. While it is commonly said to have been the first program to use [[tabbed sheet]]s, [[Boeing Calc]]<!-- 3.0 1987, possibly earlier --> actually utilized tabbed sheets earlier.<ref name="boeingcalc">{{cite web| url=http://www.boeingcalc.com/ |title=Boeing Calc dot com |archive-url=https://web.archive.org/web/20060219103549/http://www.boeingcalc.com/ |archive-date=February 19, 2006 }}</ref><ref name="aresluna">{{cite web|url=http://www.aresluna.org/attached/computerhistory/articles/spreadsheets/newcrop |title=Attached > Computer history &gt "Spreadsheets" |publisher=Aresluna.org |date=2004-09-22 |access-date=2015-10-15}}</ref> It currently runs under the Windows operating system. For years Quattro Pro had a competitive advantage, in regard to maximum row and column limits (allowing a maximum worksheet size of one million rows by 18,276 columns). This avoided the 65,536 row by 256 column spreadsheet limitations inherent to Microsoft Excel (prior to Excel 2007). Even with the maximum row advantage, Quattro Pro has been a distant second to Excel, in terms of sales numbers, since approximately 1996 to the present.{{citation needed|date=January 2017}}

When version 1.0 was in development, it was codenamed "Buddha" since it was meant to "assume the [[Lotus Software|Lotus]] position", #1 in the market.{{citation needed|date=January 2017}} When the product was launched in 1988, its original name, suggested to Mr. Kahn by Senior VP, Spencer Leyton at a Vietnamese restaurant in Santa Cruz, was '''Quattro''' (the [[Italian language|Italian]] word for "four", a play on being one step ahead of "1-2-3").{{citation needed|date=January 2017}} Borland changed the name to Quattro Pro for its 1990 release.

The common file extension of Quattro Pro spreadsheet file is .qpw, which it has used since version 9. Quattro Pro versions 7 and 8 used .wb3, version 6 used .wb2, version 5 used .wb1, and DOS versions used .wq2 and .wq1.<ref name="file-extensions">{{cite web|url=http://www.corel.com/content/pdf/wpx4/corel-wordperfect-office-X4-reviewers-guide.pdf |title=Corel WordPerfect Office Reviewer's Guide - Appendix A: Supported File Formats|page=29|publisher=Corel.com|access-date=2015-10-15}}</ref>
