Wait a minute!  You are from DEC and you don't know about this bug? 8-)
Actually I am surprised that it hasn't been fixed yet, as it was reported
in 3.0. Oh well.

The problem is apparently in the 8-bit character i/o that was attempted
in Ultrix 3.0.  It is a known bug when using `` and "" together. 
Let's hope that it is fixed in the next update.
