I have an array of entries I would like to print.

Being arr the array, I used just to write:

puts arr

Then I needed to use the DOS format end-of-line: \r\n, so I wrote:

arr.each { |e| print "#{e}\r\n" }

This works correctly, but I would like to know if there is a way to specify what end-of-line format to use so that I could write something like:

$eol = "\r\n"
puts arr

UPDATE

I know that puts will use the correct line-endings depending on the platform it is run on, but I need this because I will write the output to a file.
