Function Logic:

Function body:

uint32_t TestAlphanum (hzString& word)hzChain::Iter& ci, 
{
   //  Category: Text Presentation
   //  
   //  If the supplied chain iterator's current character is alphanumeric, place it and all subsequent alphanumic characters into the supplied string. Note the
   //  supplied iterator is not advanced by this function.
   //  
   //  Arguments: 1) word The found alphanumeric sequence
   //     2) ci  The input chain iterator
   //  
   //  Returns: Length of alphanumeric sequence
   word.Clear() ;
   if (ci.eof())
       return 0;
   if (!IsAlphanum(*ci))
       return 0;
   hzChain::Iter   zi ;    //  Forward iterator
   hzChain         W ;     //  For building word
   for (zi = ci ; !zi.eof() && IsAlpha(*zi) ; zi++)
       W.AddByte(*zi) ;
   if (!W.Size())
       return 0;
