def create
length = @txt.length
i = 0
while i < (length + 1)
line = @txt[i]
line.split(',')
#@arr.push(a)
i += 1
end
end

this works but as soon as i take out the comment.
i get an error something about private method split beeing called on a nil object.
I found out that this has to do with split that has to be called by self or something.
what i like to do is have an array of the split arrays.
any ideas?
i have the following method
-----
def create
length = @txt.length
i = 0
while i < (length + 1)
line = @txt[i]
line.split(',')
#@arr.push(a)
i += 1
end
end

i get an error something about private method split beeing called on a
nil object.
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.
