Thanks for the tip. I have just downloaded the complete e-book and Calibre, and converted it into a pdf file. Terry Ritchie's book is a very good job indeed; my first impression. And that's my opinion too:
"Personally, I'm hoping that as the author of this work, Terry will take a look at this topic and decide, "Hey, why don't I take that final step and make this a published work?" If he does, he can actually earn some $$ for each sale of the book from Amazon Publishing, or The Book Patch -- and, in my opinion, he deserves to earn a little extra coffee money for writing such a nice gaming guide for use with QB64. "
I only have one (small) problem: a lot of text in yellow on blue. Is there a way to change that, for example in light gray?
