To set the record straight (and followup on Macrakis's comments), NASA has decided to use Ada for Space Station. At NASA's Goddard Space Flight Center, one flight dynamics simulator is being developed by two teams to examine the feasibility of using Ada. One team is using Ada while the other is using the more traditional FORTRAN. Detailed data (collected as part of the Software Engineering Laboratory) will be examined from both practical and research perspectives to help NASA make a decision about using Ada. Ada is being used as the only development language on at least one other project at Goddard. I'm fairly sure that other NASA sites are also considering using Ada. NASA hasn't dismissed it out-of-hand and certainly doesn't consider it a joke. As far as UNIX workstations and Ada being mutually exclusive (it seems to me that Wiener's statement implies that), Verdix has a compiler running under UNIX on Sun workstations. NASA Goddard is using DEC's VMS/Ada on their Vaxen. Not everybody uses Crays. No comment from me on the other 'biggies' mentioned above. I hesitate to lump everyone together.
