When you call 'info[]', the '[]' piece is actually trying to invoke a metho=
d
in the object.

since 'info' is not delcared as an object, Ruby has no clue what to do.

Now, if you did this:

info =3D []

or

info =3D Array.new

You'd be better off.

As for stuffing 'info' with data, you can do this:

info << gets.comp

and

info.sort!

Does this help you at all?
