Just before posting previous message I checked Google for Interbase and
Aston Tate and the "official" history says that Aston Tate acquired
Interbase, Inc. in 1992 and Borland aquired Aston Tate in 1997... That's
where I took those numbers. There must be something wrong in that history...
In 1996 I was already using IB 4.x (probably that was even 1995).
