Subject: Re: [NEWBIE]: Example from Pickaxe2 gives errors... (p. 31)

For future reference, typing the code straight out of the book will
often result in these types of errors, as they use abbreviated code
listings to save space.  If you kept typing each example from
beginning to end it would work ok, because you can add to a class at
any time.  Its easier to check out the website [1] for the full
runnable code listings, in my opinion.
