[FRIAM] More on levels of sequence organization

[Frank Wimberly]

I tried to copy this mail that had the file attached:

We used the  Hearsay-II extensively as a model for how to do parallel,
distributed applications in the Robotics Institute at Carnegie Mellon.  It
makes use of levels and communication among them, up, down and within a
level.  Applications included factory automation, job shop scheduling, and
others.  As a speech-understanding system it was replaced by Harpy which
was faster.

Some will remember several other times that I have promoted this.  I'm just
trying to help.
