Thanks to all for the answers.

Yes, Bob the ball hitting the foul pole or the screen is universally understood as a home run. But the question of the ball bouncing into the screen was a question posed to me and I was not able to convince the questioner about the logic of the screen and foul pole having the same effect on a fair ball that bounded into either.

Thanks to this forum the answer is simple. The pole and the screen are in the stands and serve as visual aides for the umpire to determine whether the ball entering the stands was fair or foul. If fair on a fly=HR. On a bounce from fair ground=Double.

Thanks
