Computer code in Ebooks

[madfilkentist]

elf just called this community to my attention today, so hello, everyone.

I'm working on a book, with the plan of publishing it on Smashwords, called Files that Last. There's a Kickstarter campaign for it, but with time rapidly running out, its chances don't look good. If you want to throw $700 at it, though, I won't object!

Even without the Kickstarter money. I'll publish the book, though without the level of professional review I'd like. I'll still have a professionally designed cover and get proofreading in exchange for a promise of reciprocity.

But to get to my actual question, I've discovered from a trial run book that putting computer code into a Smashwords book and have it come out of the meatgrinder readable is very difficult. I solved the problem there by linking to code files. Has anyone else had experience with code or other difficult-to-format text in ebooks? Any advice would be appreciated.
