Hi all,
I have a couple of PIE documents which the folks at PARC were nice enough to
copy and send me. They are scanned and I've just made them available:
A Layered Approach to Software Design
(Ira P. Goldstein and Daniel G.Bobrow, CSL-80-5 December 1980)
1.9 MB
http://www.dolphinharbor.org/docs/PIE%20Layered%20Approach.pdf
and:
An Experimental Description-Based Programming Environment: Four Reports
(Ira Goldstein and Daniel Bobrow, CSL-81-3 March 1981)
3.18MB
http://www.dolphinharbor.org/docs/PIE%20four%20reports.pdf
Both are (c) Xerox. I hope there is no problem posting them.
Hope these are useful,
Jerry Bell
