Hi Paul,

This is the only patch for Chapter CPU. Please take a look.

"ideal" can be used as a noun. I don't think this hunk is necessary.

This is quite true, but making it a bit less confusing to non-native
English speakers is worth something.  Not that I am volunteering to
confine myself to the 850-word vocabulary of Basic English, mind you!  ;-)

So Akira has a good point, but I will take Junchang's patch.

Hi Akira,

You are right. I never realized this until you helped point this out.
I checked my dictionary which says that ideal can be used as a noun
and means 'a perfect example of what something should be like'; in
this respect, word 'case' is unnecessary. Thank you so much. Happy
learning :-)

Hi Paul,

Thanks. Then I will explicitly mark this type of patches as
suggestions if there are any in the future. It is a great pleasure to
help improve the book.
