Yes I agree that it makes no sense, but I wanted to see how zip method= works with File IO with a simple experimental code.
My point= is why the second line of input is discarded.

Hi,

this simply makes no sense. When you go through each line "by hand&quo= t;, the
"zip" is completely useless. You might as well write

file =3D open( ARGV[0], "r" )
puts "#{1}: #{file.readline}"
puts "#{2}: #{file.readline}"
...

I guess what you actually want is something like this:

File.foreach(ARGV[0]).with_index do |line, i|
=A0 puts "#{i + 1}: #{line}"
end
