Also the flight software for Northrup's F-20 is written in Ada & is successfully completed its flight tests. In fact, Ada is a very nice language to use for MANY applications and the people/companies that have used it, report tremendous productivity improvements (the gains come during unit testing & integration & test phases, there hasn't been enough time yet to determine the gains during the maintainace phase). The major cost of Ada is training. There are 2 reasons for this: 1) It unquestionably takes more time to for someone to learn Ada to the degree where they can FULLY utilizies its capabilities and FULLY understand the language. However, this is at least partially do to the fact that there is so much capability in Ada. [NOTE: this is base both on my personal experience in learning Ada & in teaching it.] 2) Most programmers don't know Ada. The second problem will decrease over time as more & more people learn Ada. Also some of the cost of this instruction will be recoverd since people will not have to be learn a new language every time they switch to a new machine or project once they have learn Ada. Ed Colbert
