Actually, we had a discussion about this a few months ago.  There's more to
it than this.

Before you start, make sure you have enough LABELLED tapes to contain the
whole file.  You get a chance to write a label on the first tape but not
subsequent ones.

I don't think you have to use a "scratch" tape - any tape will work.  Also,
skip the "IBM".  It used to be that HP would only read IBM tapes, not write
to them.  I presume that that is still true.  The default is ANSI.

Make the blocking factor as large as you can (10 is miniscule), otherwise
the tape will be mostly inter-record space and you will need many more
tapes than you think and it will take forever to write.  There is a limit
and I think it is 255.
