I think what Chuck did by wrapping it in a normal tape block would work as well, other than which convention of block rounding does it follow. I'm trying to find the email exchange I had with Bob about the flag records that he added. I think I was confused about what they actually mean. I need to look to see what the last longword of a SIMH .tap actually is. I would think it would be the physical EOT longword. Another rathole we can go down is what happens when you want to add more metadata. Do you checksum the tape image separately?
