What's the best way to ask about code from an older book?

adamsj has asked for the wisdom of the Perl Monks concerning the following question:

I've hit a snag working through an example from MJD's Higher Order Perl and am wondering what the best way to ask for guidance is. I haven't post the code, because it's copyrighted, and I try to respect that. What's the etiquette for this?

Quoting pieces of code would fall under fair use for this case. Also here's the license for the code in question: https://hop.perl.plover.com/Examples/. And here's a github repo somebody else created for the code examples in the book: https://github.com/tomhickerson/hoperl.	[reply]

HOP has always been freely downloadable. I'm very sure there is no problem reproducing limited samples here. Update I followed Sleet's link to the licence agreement. Apparently you need to cite this: "from Higher-Order Perl by Mark Dominus, published by Morgan Kaufmann Publishers, Copyright 2005 by Elsevier Inc". I personally would just link to the online source.
