Dear Professor Winston,

.SKIP 2
.INDENT 6

	Enclosed are four copies of the paper I wish to present at the
Fourth International Joint Conference on Artificial Intelligence.
The research was done as a member of Green and Waldinger's
Automatic Programming Group at SAIL, during the past year.
I am now a third year graduate student at Stanford. If there is any further
information you request, please contact me.
	The major synthesized program is a simplification of the one described in
your dissertation. If my treatment of the differences between 
them is inappropriate, please
suggest revisions.

Eagerly awaiting your comments on the paper,
