I suggest that Ada fulfills all your requirements, and according to numerous other contributors to this thread is supported and long-lived enough to qualify. Markus Kuhn, University of Cambridge, UK, wrote in a different discussion, "I believe that Ada95 is tremendously underhyped." My own work is in Ada95, building the software controls for the National Ignition Facility, which will be the world's largest precision optical instrument - a laser to perform fusion experiments. We expect about half a million SLOCS and we design for 30-year service life. (A paper in SigAda 98 Conference Proceedings, to appear in Ada Letters, describes our control system). Ada meets or exceeds every one of our requirements: distribute software over about 500 computers (mostly VxWorks PowerPC's and Suns) using CORBA; incorporate commercial GUI and DBMS products; operate some 60_000 control points (of more than 400 distinct types). -- John Woodruff N I F \ ^ / Lawrence Livermore National Lab =====---- < 0 > 925 422 4661 / v \
