This means that @arr is nil, that is, you are doing

    nil.push(a)

So you need to initialize it first:

    @arr = []

There are a few other errors in your code, for example you didn't assign 
to a:

    a = line.split(',')
    @arr.push(a)

and your loop should be while i < length, not while i < length+1. As has 
been pointed out, there are more ruby-like ways to do this loop.
