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).

A few paragraphs under that example, still in the How To Read This Book section, you will find:

And in some cases involving the modification of an existing file where the lines to be changed may not be immediately obvious, you will also see some helpful little triangles on the left of the lines that you will need to change. Two such lines are indicated in the previous code.</blockquote>

Is that not clear?

Not to worry. You were stuck, and I pointed out what you missed (it happens). In all, a good outcome.
