[SunHELP] problem with dd command - extra blank chars added

[Eddie Watkins]

Hi

We have a file that can have a random number of variable length records.  We
need to dump the file to tape with a fixed length of 512 bytes per record,
so use the following command dd if=file1 of=dev/rmt/1 cbs=512
conv=sync,block.

When this is done it adds an extra 512 blank spaces to the end of the file.
I have checked using more, vi etc that there is not a blank line at the end
of the file, but doing an octal dump shows that the final record ends with a
newline sequence '\n'.  Is there any way to remove this final newline before
the dd command is processed or any other way that the 512 blank chars can be
removed ?

Thanks
