The statistics about COBOL where made in 80's and were gathered in institut= ions and contracting companies in US at that time. Let's suppose that the 9= 5% number was true in *that* context. Now, move forward 3 decades. Those banks that were operating 30 years ago i= n US and are still alive very likely still use the old stuff, but this says= nothing about all new banks that popped up since then, all new contracting= companies that were created since then, and all whole new markets that pop= ped up everywhere in the world, *outside of US*. Personally, I was involved in three different systems of the "financial" ca= tegory (one insurance, two trading) and the insurance company was *replacin= g* their old COBOL system with a new one, while the trading companies are y= oung and do not even have any COBOL stuff to replace. I presume that my exp= erience is not unique. Today, everybody is blindly repeating the old statistics from that narrow o= ld context like a universal truth. Everybody is sure that finance is done i= n COBOL, but I've never actually met anybody who has seen a single line of = it (that of course does not mean it does not exist - but certainly shows th= at the market has moved a bit). Today it sounds more like an urban legend t= han a valid statistics. That number today might as well be 5% instead of 95%. > I read somewhere that mainframe sails are essentially constant You mean - the few old US banks are periodically replacing their aging hard= ware, but there are no new installations and that's why the sales are const= ant? Sounds very reasonable. Then it's rather 5% today. --=20 Maciej Sobczak * http://www.inspirel.com
