DBS is a set of APIs that permit access to the Fileman database without any user
interaction. In classic FM, the APIs would support user interaction. For
instance, call the DIC API and it could ask the user for the name of a record to
be selected and then if it matched multiple records, a list of choices would be
presented and finally a selection would be returned. The UI was handled by the
call. With the DBS, only arrays are passed back and forth and no UI is
presumed.

I believe they used the term Shell to mean a framework, both visual and
non-visual, within which one could create a custom and extendable client app.
So, it is much more than a language, as I take it.
I believe Randy Cox has a CD that they can send you to give you a much better
picture of what it is. If you have trouble contacting him via the Email, let me
know.
