Contents • • • • • • • • Characteristics [ ] Historically, Quattro Pro used keyboard commands close to. While it is commonly said to have been the first program to use, actually utilized tabbed sheets earlier. It currently runs under the Windows operating system. For years Quattro Pro had a comparative 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 regard to the number of sales, since approximately 1996 to the present.

[ ] When version 1.0 was in development, it was codenamed 'Buddha' since it was meant to 'assume the position', #1 in the market. [ ] 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 word for 'four', a play on being one step ahead of '1-2-3'). [ ] 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. Origins [ ] The original Borland Quattro electronic spreadsheet was a DOS program, the initial development of which was done by three Eastern Europeans, one of whom, Lajos Frank, was later hired by Microsoft. An article appeared in PC Week in 1985, quoting a maker of spreadsheet templates saying that he was in close contact with Borland, and that Borland was developing a spreadsheet.


At the time, there was absolutely no such development being undertaken by Borland. After they both read the article, Philippe Kahn and Spencer Leyton had a casual conversation where they joked, half-way seriously, about perhaps developing a spreadsheet to compete with Lotus Development's 1-2-3.

That led to Mr. Kahn setting an appointment with an agent for some Eastern European software developers, Robert Stein of Andromeda Software, which was also involved with the game. That led to an agreement negotiated by Mr. Leyton and Mr.

Stein, providing for the development of the original Quattro. Quattro was written in and principally by, Lajos Frank, and Chuck Batterman. It was praised mainly for superior graphics on DOS. Borland acquired a replacement product called 'Surpass', written in.

The main designers and programmers of Surpass were also hired by Borland to turn Surpass into Quattro Pro: Bob Warfield, Dave Anderson, Weikuo Liaw, Bob Richardson and Tod Landis. They joined other Borland programmers including Chuck Batterman, Lajos Frank, Tanj Bennett, Rich Reppert and Roger Schlafly. Bob Warfield later became Vice President of R&D at Borland.

All eventually left Borland. Quattro Pro shipped in the final quarter of 1989. The Borland main office was near the epicenter of the and the building was severely damaged when large and heavy air conditioners on the roof of Borland's main building were thrown upward by the quake, and came crashing down upon the beams running across the top of the building. The beams were damaged to the point where they required injections of epoxy in order to make them sturdy enough to support the building again.

In addition, the sprinkler system was triggered. The building was closed for months. All the computers were removed, placed on the tennis courts, washed down (acoustic ceilings rained gray mush onto everything when the sprinklers ran) and dried with hair dryers. Those that booted up were put to work. Quattro Pro finished final testing and was sent to manufacturing from those computers running on the tennis courts in the (fortunately) sunny and dry autumn weather.

Lawsuit [ ] Some have claimed that Quattro Pro was the first to use the tabbed notebook metaphor - but another spreadsheet,, used tabs to multiple sheets, and allowed three-dimensional references before Quattro Pro was on the market. (Boeing Calc was so slow that its multiple sheet capabilities were barely usable.) Quattro Pro was the subject of a major.

Lotus argued that Quattro could not copy Lotus 1-2-3 menus (it did copy the menus). Borland supplied the 1-2-3 menus as an alternative because keystroke compatibility was needed in order to run in 1-2-3 worksheets. Borland argued that most cars operate the same, but they are not necessarily made the same. So, Lotus could not rationally 'own' the way its program behaved.

The district court ruled in favor of Lotus, but the appellate court ruled that the 1-2-3 menus were functional and not copyrightable. The case went all the way to the U.S. Supreme Court which split 4 to 4 ( recused himself).

This left the lower court ruling intact, which was a victory for Borland. However, the broader issue of whether a company can own and protect the way its program behaves remained unresolved. By the time the case was resolved, Borland no longer owned Quattro Pro. Borland sold the spreadsheet to six months before the final decision was handed down.

Quattro Pro for Windows [ ] Quattro Pro began as a program (like Lotus 1-2-3) but with the growing popularity of Windows from Microsoft, a Windows version of Quattro needed to be written. There was almost nothing from the DOS code that could be moved to the Windows project, so the Quattro Pro for Windows (QPW) was written from scratch.

Both the QPW and for Windows codebases (the latter being another Borland database application) were based on Borland's internal pilot project with object oriented UI code for Windows. This project ran simultaneously with the Borland language group investigating the desirability of a compiler, and the company decided to make a bet on C++.

However, the C++ compiler was not ready at first, and OO code for both projects was started in C with OO emulation through macros. As the Borland Turbo C++ compiler became available internally the projects converted to using C++. Charlie Anderson was put in charge of the project and he soon had,,,,, Alan Bush,,,, Tod Landis, Gordon Ko and working on the project. Other engineers joined later. Eventually the team numbered nearly 20. The object model was inspired by the object model, modified by Mr. Spencer were in charge of the spreadsheet engine (written in assembly language) while Mr.

Low wrote a large chunk of the UI. The product was internally codenamed ' for the Norse god of Thunder. QPW featured two major innovations. First, it was the first Windows spreadsheet with multiple pages with cells that could be linked together seamlessly, a feature from Quattro Pro which QPW extended.

Second, it was the first released Windows program to have an (or ) available by right-clicking on the object. Although this idea was first seen on the, the idea had not been implemented on a major Windows program. Paradox for Windows shared this feature, and it was shown off by at a Paradox user conference over a year before QPW was released. Both these ideas became widespread in the software industry. QPW was one of the first big applications written in C++ on Windows, and it pushed the Borland C++ compiler to the limit. One reason why the Borland C++ Compiler was so good was that it had to compile and link the massive QPW code base successfully. The technical risk of the QPW project was immense.

The object model was untried and might not have worked for a spreadsheet. The user interface (UI) was new (for Windows programs at least). No one knew if the C++ compiler could generate fast enough code. As it turned out, the program worked.

It was fast, it was close in feature set to Lotus 123 and Excel, and the 'right-click for properties' user design was reasonably understandable. At one point, it was hoped that QPW and Paradox for Windows would be able to share a common object model. That proved impossible despite serious thought and design efforts. QPW was finally released in September 1992. The Quattro Pro marketing team had chosen to bundle both Quattro Pro for DOS and Quattro Pro for Windows in the same box labeled 'WIN-DOS' at a price of $495. Customers and reviewers expecting a pure Windows application responded with confusion and outrage, believing the product was merely a DOS application with windowing capabilities.

Shortly thereafter QPW was re-packaged by itself and priced $129, receiving accolades for Borland's long-delayed pure Windows spreadsheet and its popular price. Eventually it sold well (after the price was slashed to just $49 a copy). Work was started immediately on a new version with a brand new team of engineers led by; including and. Borland purchased from to add a new feature to the program. Colin Glassey came from Brio to help with the integration of that technology.

After a year and the merging of the old team and the new team, QPW 5 was released (the reason for the jump in version number had to do with keeping up with the DOS version as well as it looked good). QPW 5 sold well also, though the + Word combination was gaining steam. Email Contacts Extractor there. Work then started on version 6 (now with as project lead). Midway through the development of version 6 a strategic decision to work closely with the word processor was made. It was a direct attempt to push back at the Microsoft Office one-two punch of and Microsoft Excel. The other big issue with Version 6 was the advent of. This was a significant modification to the Windows operating system with a major change to user interface guidelines.
