Seven years ago I wrote asking about /dev/null on the 400. Seems like
there is one now plus /dev/zero. /dev/qsh-stdin-null on our V6R1
system exists but I found it as a regular character file that grew as
you wrote stuff to it. /dev/null and /dev/zero are 'special' files.

Anyway, I'm just putting this information out there now for future
