Sorry - I can't reproduce this the way it is described here on my V8.3
Alpha.  After entering the characters, and pressing the up arrow three
times, I am returned to the "$", without a dump.  I have reproduced this
technique on two different Alphas, both running V8.3, and have not
reproduced the reported behavior.

It will be interesting to see the slides.
