Steve, thank you so much for clarifying this. I think I need to read some more and understand how records are allocated. Is there any documentation online explaining it ? Are physical records the same as blocks ? I am supposed to be sending this dataset to an AIX box without translation, where they are going to read it using ab initio. I had just told them to look for the 4 byte RDW before each record. So they did not code for the occasional BDW. They cannot exp BDWs to occur after a fixed number of bytes or records, right? Every day I realize how little I know.
