  if (lok >= 0) {
    long entry = book->dec_firsttable[lok];
    if(entry&0x80000000UL){
      lo=(entry>>15)&0x7fff;
      hi=book->used_entries-(entry&0x7fff);

 if (lok >= 0) {
    long entry = book->dec_firsttable[lok];
    if(entry&0x80000000UL){
      lo=(entry>>15)&0x7fff;
      hi=book->used_entries-(entry&0x7fff);
