For this kind of need, you also might want to contact Jim Starkey,
principal
author of Interbase, now available in open source as Firebird.
The original Interbase was first released on VMS. The VMS code is still in
Firebird but has not been built on VMS in some time, but Jim might be
interested in your situation.
Interbase/Firebird is a very cool product. I last used v4.x on VMS.
