Please could someone tell me what the green pointers to code indicate in the PDF? I reported this in errata to possibly assist Sam yet there is no discussion there.
Thanks in advance, Malcolm
No explanation of what green pointers indicate. In the How to read this book section the below code exists with green pointers pointing to some lines of code. No where I can find does it explain what these green pointers indicate(I have read to page 88 so far).
