Can you separate the codes? All of them should be three digits, but usually the computer spits them out in ascending order.

You really need to separate the codes out for us - grouping those numbers in three's don't produce anything meaningful. You will not have 2 digit codes and a 3 digit code - it will be either one or the other, and '94 should use 3 digit codes.
