Using GOTO and IF-THEN-ELSE G-code Commands

Great suggestion. How does this look (see page 2): https://rick.sparber.org/GcodeLogic.pdf

I have also rewritten the explaination of the code example. As the author, I am unable to see what does not work for the readers so PLEASE give me your comments.

As an author of two technical books as well as a contributing author to other books and 100s of magazine articles I am only too well aware of the difficulties of determining how the average reader interprets one's work. This applies much more to technical works because it is hard to strike the right balance between those with the minimum starting knowledge and those with much more. It is easy to lose one extreme or the other if the balance is wrong. I do not read fiction ( never get past the first page when I have tried ) but I guess that these considerations do not apply to that genre.

I think that your page 2 additions are much more likely to suck the reader in. Great choice of variations on the same theme, very clever. You state that conditionals and navigation statements will be discussed but then you start talking about variables without initial explanation. I would suggest an early mention that variables are useful in conjunction with the conditionals and navigation statements.
