Yes, you would have to: Open the database, Get the record, and Lock
the handle. This is sort of what happens when your app loads, but
automagically. You also have to unlock/release/close. But that can
be at the entry and exit to your code. The rest is to change
Bigarray[] to *Bigarray and point it at one of the records.
Note that these can be resource databases. My concorde program uses
this technique (as does my MIDI player) - I generate the compressed
data offline and just lock the resource I am decoding.
