David Marceau said (speaking of Microsoft): One big problem...they're not into open source. Another big problem with Microsoft and Ada -- they're not into standardization. You can pretty much guarantee that a Microsoft Ada would have additional features not permitted by the standard and would ignore features that are required by the standard. See Visual C++ for numerous examples. (I've talked with some Microsoft personnel about validation of their C/C++ and Fortran products. They're interested in "what their customers want" rather than conformance to standards. I guess that's what you get when you have a monopoly.) Phil Philip W.
