Subject: How to duplicate elements in array?

Hi,

something I couldn't quite figure out (sorry for posting so soon after
my last question)...

a = [["ABC", "30", "1"]]

I want to duplicate/copy the element. This is what I'm trying to get:

a2 = [["ABC", "30", "1"], ["ABC", "30", "1"]]

What I did was simply

a2 = a + a

=> [["ABC", "30", "1"], ["ABC", "30", "1"]]

That works.

I then tried changing a single element.

a2[0][1] = "test"

puts a2.inspect
=> [["ABC", "test", "1"], ["ABC", "test", "1"]]

Of course, I just intended to change the first value, not both of them.


Can anybody explain please what I can do about this?

Thank you!

Chris
