Hmm...
Figure 13.6 will not run. Line 8 results in Error 52. You have to change fastlength to a value 2 or greater for the script to run.
Figure 17.1 will not run correctly either. The attached picture shows an incorrect output. I've looked at it until I was blue and it has nothing to do with word wrap or quotations.
There are at least two more, but I don't remember which ones they were.
