- Well, it has been a while, but if I recall correctly, this message
- will come up if the "end of record" marker gets corrupted or sometimes
- if there is a version number mismatch (very rare). The end of record
- marker is a 0D, I believe, and sometimes what happens is that it gets
- converted to something else during the transfer process. Typically
- this happens when you transfer the export file to another platform and
- don't specify a binary file transfer. I'm not sure what tools there
- are under VMS for viewing the hex contents of a file, but what you
- should do is create a new export file and take a look at it. If your
- viewer can display hex and the ASCII equivalent side by side, you
- should be able to tell very quickly what the end of record marker
- should be. Then view the corrupted file and see if it is different. If
- so, then you are going to have to convert them back somehow.
