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. ==================== Leonard S.
