Using a string as a variable at run time

Question

I have a string, which has been created at runtime. I want to use this string as a variable to store some data into it. How can I convert the string into a variable name?

Answer 1

You can use eval() for this provided that you've declared your variable first:

>> foo = []
>> eval("foo")[1] = "bar"
>> foo[1]
=> "bar"

Here are the docs.
