Someone forwarded to us the following extract from a message by Wilfried Rupflin : >> The user base for Eiffel or Dylan is much higher it seem > The user base for Eiffel seems to be (still) higher, indeed. > But it seems that very few people are *using* Eiffel really. > (That's at least my impression [...].) The impression is quite wrong. To talk about what we know: there are more than 10,000 ISE Eiffel licenses around (we do not know the figures for the other Eiffel implementations). A number of significant commercial products have been built with Eiffel. Some of the largest successful O-O projects are being developed with Eiffel; one of the biggest and most impressive is the CALFP project, a 500,000-plus-line investment banking system entirely written in Eiffel, which was featured in the May 8 issue of ComputerWorld as well as in other trade publications. This is a complex derivative trading system which is giving that bank a major competitive edge. An interesting aspect of this development is that only 1/3 of the team (25 people or so located partly in London and partly in New York) are software people; the others are financial analysts, economists or bankers who have however learned Eiffel very quickly thanks to the simplicity and clarity of the notation. You can get reprints of articles about this and other projects, or a freesubscription to the Eiffel World magazine, by writing to us.

None of this is meant as a negative reflection on Beta; just a correction of an erroneous impression posted here. -- Richard Bunbury, ISE Customer Support Reply to: For answers to common questions, information on Eiffel, books, TOOLS, ISE etc.: Use our Web page at http://www.eiffel.com, or anonymous ftp://ftp.eiffel.com
