spy

["M. V. LaPolla" <CS.LAPOLLA%r20.utexas.edu@CSNET-RELAY>]

I have to complaints about spy. 

1. It doesn't allow the user to choose what he wants to see,
i.e. no skip, leap etc.

2. It moves across the screen and doesn't stop so that
sometimes a predicate begins at the right hand margin
and  ends at the left making viewing difficult.
