It was ASCII and after the binary issues of tp was a welcome relief. The format was also extensible (thanks to bug in the original implementation). - cpio was USG and worked best with a find(1) script/automation - which was good for controlled distributions but poor for interactive use. It was also binary originally (with PDP-11isms builtin) The real issue in the end was cpio being part of System III many/most universities did not have it originally, so the tp/stp was what we used, which was replaced by tar. pax has a user interface that work either ways, and the USENIX public implementation can read both tape formats.. Clem PS At Masscomp, I once wrote "car" but no one ever wrote "tpio".
