Has anyone ever tried such a port? Robert in the past has said the issue was not difficulty but demand. DEC funded the Alpha port, and that certainly constituted demand on the Alpha side. > Oddly, we'd really like such a thing, so we could move our > source base away from Ada83, while still supporting > our VAX/VMS customers... In a similar position, I am less attracted to that path because a straightforward GNAT port would only work on the more recent versions of VMS where DECthreads are more mature. There are a lot of VAX sites at V5.5-2, in situations where stability is more important than new features. Be sure to characterize your customer base according to the version of VMS they run on VAX. Sticking with DEC Ada (83) allows operation back as far as VMS V4.2, which is much further back than any customer will need. Larry Kilgallen
