This was Bruce's solution to copy huge files to tape, files too big for tar
(I bet you didn't know that tar had a limit, did you?)

To load the tape,

#!/bin/sh
#
# script file to put specific stuff to tape that is to big for tar to handle

dd if=fromtape.scr  of=/dev/rmt0.1 bs=65536  # rmt0.1 = Don't Rewind-on-Close
dd if=bsum.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=clas_fsc.ld.Z of=/dev/rmt0.1 bs=65536
dd if=clms.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=dclm.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=detd.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=drwd.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=fref.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=govt.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=oref.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=parn.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=rlap.ld.Z     of=/dev/rmt0.1 bs=65536
dd if=uref.ld.Z     of=/dev/rmt0   bs=65536

Note that the first file it writes to tape, is the script to read the rest of the
tape, fromtape.scr.

His directions to read the tape were,

Load the tape, presumably to /dev/rmt0, then

    cd /some/directory/that/had/plenty/of/space
    dd if=/dev/rmt0 of=fromtape.scr ibs=65536

This read that first, fromtape.scr file.  You then invoke it,
    ./fromtape.scr

The fromtape.scr script was

#!/bin/sh
#
# script file to get specific stuff from tape which tar can't handle

dd of=fromtape.scr  if=/dev/rmt0.1 ibs=65536
dd of=bsum.ld.Z     if=/dev/rmt0.1 ibs=65536
