ascii code provided in the book doesn't match the wiki page
the ascii codes of "newline", "backspace" and "double quote" provided in the book are 128, 129 , and 34, however it didn't match any thing I searched on the net. according to wikipedia , the codes should be 10 , 8 , and 34.
maybe this issue doesn't affect anything, but I want to make a note here.
Re: ascii code provided in the book doesn't match the wiki page
You are correct, the keyboard codes for the special keys are not ASCII.
Key pressed Code Key pressed Code
newline 128 end 135
backspace 129 page up 136
left arrow 130 page down 137
up arrow 131 insert 138
right arrow 132 delete 139
down arrow 133 esc 140
home 134 f1–f12 141–152
