Thanks to Glenn Cole, Michael Abootorab and Lars Appel who took the time
and trouble to help me with these mysterious HPVT and HPSTDIN variable. I
went back and forth with each of these kind folk.

The last nail was pulled out of the coffin by Glenn who pointed me to the
HP3000-l archives to a posting by Eero Laurila on March 23, 1996.
