It would be nice for the community to put some closure on this though.

The fact that you have one file whose transfer is dubious would mean
that this problem could surface with any other file.

And finding the real problem would help others in this newsgroup should
they ever encouncter a similar problem.


In particular, I would be concerned about preservation of the end of
file marker for the last block.

DUMP/HEADER gives you some information about that:

AKA, the last byte is byte 471 in block 1463, with bytes 472 to 512
being beyond end of file.

It is possible that your source file was like this, but when copied back
to VMS, the end of file byte was 512 (or is it 511 ?) which would add
some 30 bytes to the file, probably all nulls (which would explain your
extra line).
