This program analyzes the TSO broadcast dataset. It displays the number of available blocks and how they are used. It also displays the TSO users who have messages waiting. In addition it also does a validity check on records which are in the message pool to assure they are chained off of a user record. According to documentation, instances occur which can result in these garbage records existing.
