Hi, Terry,

I did some clean-up to the code. I also did some investigation in the marc4j, and it does not support conversion to .mrk. So I just reformat output records a little and save it as a .txt file.

Please review it and let me know if you find any problem.

Since the hard-coded value of 10 is being tested, it is OK to use a hard coded value in the substr.  OK to leave it as is as well.
