Subject: CSV with Ruby Newbie

Hey guys.

I am currently following an example in: "Programming Ruby: The Pragmatic
Programmers Guide" (pg. 663) on reading CSV files with Ruby. I am
struggling though to get the code to read a CSV file that has a header
in it. I have copied the example exactly but get the following error:

undefined method `process' for main:Object (NoMethodError)
        from /usr/local/lib/ruby/1.8/csv.rb:560:in `each'
        from solution.rb:4

My Code:

require 'csv'
reader = CSV.open("csvfile", "r")
header = reader.shift
reader.each{|row| process(header, row)}
CSV.open("csvfile", "r") do |row|
  qty = row[0].to_i
  price = row[2].to_f
  printf "%20s: $%5.2f %s\n", row[1], qty*price, row[3] || " ---"
end

(If your looking in the book then i have just adapted the csvfile to be
the same as csvfile_hdr)


Would really appreciate it if someone could perhaps point out what i am
doing wrong please. Thanks
