Hello, 

I am working on a decision support environment somewhat related to the
Program by Rehearsal metaphor.  At least one common aspect is the mapping
of:

		object -> stage

with stages being StandardSystemView/Controller, and with stages being nestable.
This is the tricky part:  Giving each stage the ability to be a Standard
System view, but allowing one to move one into another stage and have that
action AUTOMATICALLY corresopond to declaring the stage as an instance
variable in the new stage. This seems to imply a controller change.

Any ideas on how Bill Finzer did this?  Any ideas on how it should be done?

Send replies directly to me:		gutfreund%umass@csnet-relay.arpa
As I am not on the UUCP net.

P.S. can anyone help me getting copies of this mailing list sent to me
directly. A hook in netnews to do a send to the ARPAnet maybe?
