Is it possible to make a DBEdit field to automatically exit to the next field (like pressing tab) as soon as it is totally filled? DBASE used to do that automatically.

yes, it is possible :-)
You have to write some eventhandler for the OnChange event. The following code exits to the next field when you have reached 12 characters.
You may derive your own component from TDBEdit that does this automatically so you don't have to code it for each control separately.

procedure TForm1.DBEdit1Change(Sender: TObject);
begin
  if length(DBEdit1.Text) = DBEdit1.Field.DataSize then
    PostMessage (Handle, WM_KEYDOWN, VK_TAB, 0);
end;

Note: Use PostMessage instead of SendMessage (which would not work)
