When I started to work in a thermal engineering lab about 5 years ago, we all decided to use Ada for our every day programming and for the one big simulation project. Most of the engineers only had Fortran experience and had already a lot of code that we wanted reuse by interfacing from Ada. Fortran friendly arrays would have been a big advantage, but Ada failed for other reasons, too. Some problems were calculating exp(2x) instead of exp(x) (we lost a whole week on this), not correctly passsing parameters from the 7th parameter on, etc... Yes, I know these are compiler issues, but Ada was blamed for it. Today nobody uses Ada anymore in this lab. They all turned back to Fortran and C.
