Hi,

Based on some comments that I received, I slightly modified Items 9 and 11
and added Item i:

    9. ... To increment a number, simply write x += 1.

   11. ... The reason for this language design and some more examples can
       be found at
       http://www.rubygarden.org/iowa/faqtotum/abN18mrYFE49E/c/1.13.3.3.5.

    i. For Ruby and Delphi integration, consider "Apollo"
       (http://www.users.yun.co.jp/~moriq/apollo/index-en.html).

These changes have been reflected in the web page.

Regards,

Bill
