Ann: Trading Halt, page-52

Thanks @ammie. Yes, I can do it at home. The problem is I used my eyes so much in my life. I was reading books under the quilt by a torch when I was a kid because I was banned reading too much. Then started my IT business in 1985 nearly at the same time with B Gates and S.Jobs. One is retired one is dead. I am still working and loving computers and smart phones because of their technologies. My son is is also in IT business making one of the best VR games (IMO) in the world now "Earthlight" (Video here) in collaboration with NASA (he has invited and been in NASA this year, because his work much better than the similar work done by NASA) .

Yes, of course GPPO will follow GPP by 1c difference in normal conditions.
