I got enough to get started with, but still have a couple of questions:

1. What data are you given? I see two tabs, M, K01 and Routing and Parts List. Am I to read the routing and generate the parts list?

2. Also I still have the same questions about the TR-number. I can find two. They seem to be associated with lines N130 and N140. Can I depend on them being on the same line in the text file every time? Which one do you want to use or do you want to use both, separated by a comma?

I just noticed something about the data you sent me: the part numbers do not match the directories you sent me. There are over 5,000 part numbers, and 9 directories. None of the 9 directories have a corresponding part number. I will doctor up your data so there are matches.

Which leads to question number 3: what do you want to do if I can't find a directory for a part number? Do you want a stop-the-program warning message? Do you want me to silently pass over it? Do you want me to write it to a log?
