When I first wrote the try scripts, and in particular the ovdluhe.alt.c code to do what the author suggested one try, I just had the option in try.alt.sh to redefine P once. Now the user can do that but after the initial loop it loops from 2..10 (the range the author suggested) running the loop again (on the three files three times) so one can see what the author means. The try.sh script has the updated idea by the judges of printing two lines, not one, after each prompt. Rebuilt index.html from updated README.md.
