   As in all things eunichs, it depends on which one.  BSD UNIX dd knows
   about blocks and records on tapes, System V knows about blocks, but
   not records.

   So if you have an ASCII data file on tape in 80 byte records and you
   use BSD dd you can get it converted on the fly to stream-LF text
   that just happens to have 80 bytes on each line.  Or you can convert
   stream-LF text files to blank padded records as long as the longest
   line of text, but if you live on a System V, you get to roll your own.
