Jim, I suggest you relax a bit. As to the fourth claim of yours, you could try getting in touch with Bjarne Stroustrup and ask him about places it's being used. Last time I heard, central telephone switching gear (the size of 5ESS) is coded in C++. After all, this _is_ AT&T... These animals implement CCITT Signalling System number 7. The specs are 1500 (A-sized) pages of gory details and 500 pages of verification and validation suites. I posted the table of contents of SS7 to comp.std.internat some time ago. Telephone exchanges are "hard realtime, life-critical, very big, very complex" to check off your list. I'm not particularly interested in arguing with you, so this is only for the benefit of those who would otherwise tend to believe you. -- [Erik Naggum] Professional Programmer Naggum Software Electronic Text 0118 OSLO, NORWAY Computer Communications +47-2-836-863
