For the benefit of those of use without the 1.9 version of the book, can 
you post the code you are trying to run, and the exception you get in 
response? I don't think you will be held liable for copyright :-)

For a definition of puts see http://www.ruby-doc.org/core/ and look for 
'puts' in the right-hand column.

Also the old version of Programming Ruby:
http://www.ruby-doc.org/docs/ProgrammingRuby/html/ref_m_kernel.html#Kernel.puts
http://www.ruby-doc.org/docs/ProgrammingRuby/html/ref_c_io.html#IO.puts

Perhaps what you are looking at is one method using the return value of 
another as a parameter. For example:

  def foo
    123
  end

  puts foo     # same as: puts(foo())
