Just to clear up a misconception:

4th Dimension can be used as a front end to various SQL databases, just as
Paradox can.  The most general linking medium is DAL, through which 4D
can effect queries on any SQL databases running on machines which support
the DAL connectivity language (currently VAXen, soon others).  In
addition, there are several other connectivity packages, such as
SequeLink, and specific connectivity packages for Oracle and Sybase (the
former available now, the latter very soon).

In several months, ACIUS will market what works, practically speaking, as
a 4D client-server package (i.e., the throughput will be effectively
similar, though the technology will be a little different).  Perhaps it is
this product which Bill Yock is referring to.  However, this product will
NOT replace the SQL connectivity packages available nor or soon.
