Subject: Re: Newbie: fastcsv: Read rows, print rows

Thanks for such a rapid, patient response!

You certainly helped me get "unstuck".  Appreciate the references.  I
had found the doc pages but was still laboring.

For the record, here is my working code.  No rocket science, but may
be useful to someone.

All the best!

<code>
require 'rubygems'
require 'fastercsv'

infile = "infile2.csv"

FasterCSV.open(infile, "r") do |row|
        row.each{|row| puts "row: #{row.inspect}"}
end
</
code>
