Hmmm. Perhaps I was a little hasty. I was speaking for the past
and for the future. The present is a little more difficult.

As you know, Interbase (the product) is still owned by Inprise
(aka Borland). Interbase Software Corporation (aka Interbase-IV)
is negotiating with Inprise to take the product open source.

In the interim, Inprise is giving away V6 betas and selling V5.6.
Also, it is anticipated that even after emancipation, Inprise will
continue to sell V5.6.

In the past (Interbase-I and Interbase-II) separated the the
engine (formerly known as the access method) into an image
separate from the Y-valve so a subsequent release could access
both. This practice appears not to have been followed by
the most recent Borland engineering management, now happily
gone, for reasons that are hard to fathom.

I think, given appropriate tweaking, the acting general manager
of Inprise's Interbase division and president of Interbase-IV
can be convinced to fix this. I shall commence to lobby
