[sword-devel] BibleTime indexing problem

[scribe777@gmail.com]

Gary, if you add this line to your test program (which I suspect Bibletime did similarly at some point) you should get similar values in tmpKey at that point:

 >                 return -1;
>         }

 ((VerseKey *)book->getKey())->Headings(true);

>         book->setPosition(TOP);
>         return 0;
