Is there a good small example somewhere on how to set up and use an
external index file in Tdbf?  The Tdbf Tutorial is scant on this type
of information.  The Tdbf Manual says what everything is but has few
examples.

That is fantastic!  It is exactly what I was looking for.  A bonus is
that it also answered a few other unrelated questions.  Small projects
like this make learning Lazarus a lot easier.

By the way, a little comment to example:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
FieldDefs.Add('ID', ftAutoInc, 0, True);  ...  Append;  //
Fields[0].AsInteger:=100;  // Do not fill 'ID' because its type is
ftAutoInc  fields[1].AsString:='France';

Thank you!  Another great example.
