Our research indicates that the Ada vendors seem to be doing fairly well financially, that the market is stable or growing for Ada products, that compilers continue to be deployed for new architectures and for latest-release major OS's, and that many Ada vendors are willing to invest in cost-intensive product improvements (e.g., Ada 95-specific optimizations and optional annexes). Another factor is the existence of GNAT, which is available as "open source" software. This means that we could continue using Ada indefinitely as long as there are experts available to port the compiler to all platforms and OS upgrades we would use in the future. At this time, Ada Core Technologies (ACT) has this expertise and sells support contracts for these purposes. If ACT were to disappear, the worst-case scenario would be that we would need in-house expertise to maintain GNAT from sources. But ACT appears to be doing well financially. In short, our project does not foresee any failure of the Ada infrastructure in its lifetime. -- Stanley Allen mailto:srallen@hti.com
