I used this on-line compiler and finally had success. I do not think that there is anything wrong with your instructions, or code. Thank you very much for sharing.

I now have my needed numbers.
However, I used the on-line compiler out of desperation. I can only wonder what access I have given the dark web and who owns my computer, now. That is not a complaint, but rather a warning to others.

Much thanks. Cheers. t1d
