There's the documentation:

   http://fastercsv.rubyforge.org/

You'll find basic reading and writing information on this page in  
particular:

   http://fastercsv.rubyforge.org/classes/FasterCSV.html

There are also some examples in the source:

   http://viewvc.rubyforge.mmmultiworks.com/cgi/viewvc.cgi/trunk/ 
examples/?root=fastercsv

The above should be on one line.  You may also need to add a:

   require 'rubygems'

before requiring FasterCSV, depending on your environment.

> fastercsv.open("rfile2", "r") do |csv|

There is an error is on the line above, which needs to be:

  FasterCSV.open...

>         csvData.each{|row| puts "row: ${row}"}

Change csvData to csv in the line above.  Also replace ${row} with # 
{row.inspect}.

> end

That should get you running.

You can do this a little easier using foreach():

   FCSV.foreach("rfile2") do |row|
     p row
   end

Hope that helps.
