The first if does return a hash with the keys and values so I know that
works.  The first one is for any negative values as it is only indicated by
a 0 or a - in position 215 of the string.  The second if is for the positive
values, so I'm guessing that when the script is processing the lines and has
a positive value its not skipping the negative if and going to the elsif to
process and store the info in the hash.

Basically what I'm trying to do here is gather the account balances and
account numbers and store them in a hash and if there are accounts with the
same number to store their balances as an array in the hash value to add
them later when I iterate over the hash.

If there is a better way to do this that I'm not thinking of please share
with me so I can better my ruby knowledge.

Thanks!
Tim
