The key for checking whether one of the multi-line records is a keeper or not is at position 19 for a length of ten on the first line (segment '01' in our parlance.)

There could be hash characters in some of the fields -- many of them are freeform and take addresses, comments, etc. There will not be any in the first position though, other than the ones that denote new records. Thanks sauoq.
