Re: [3.0.4] Request: please revive the deleted arrays yyrhs and yyprhs

Thank you, Akim!

  At that time, I was puzzled. 
  Had some rapid rescue been done, it could saved our much time. 

  Not so long time after the time, I decided to write my own program to compute 
the lost information from the rest information in generated C program sources. 

  Fortunately, my computation coding effort succeeded．
  So, I am not facing the trouble now.
   
  I appreciate your great offer, thank you!
