If I understand correctly, the behavior of your program should be like this:
> Say something
text1 [press enter]
> Say something
text2 [press enter]
> Say something
[press enter]
> text1
> text2

Then, the following code should do the job:

something=[]
loop do #iterates until explicitly told to stop
  puts "Say something..."
  res=gets.chomp #read the line from the keyboard
  if res.empty? #if the line is empty, the user has only pressed enter, so
    puts something #display what he already wrote
    break #exit the loop
  else something << res #the user has entered some text, so store it
  end
end

Essentially, your code had two problems:
1- it lacked the enclosing loop, so the code would have been executed only 
once
2- instead of storing the string into the array, you replaced the array with 
the string

I hope this helps
