I tried to find a local CSTR or other machine-readable paper, without
success. Brenda does list these publications:


B.S. Baker, An Algorithm for Structuring Flowgraphs, J. ACM 24,1 , January, 1977, pp. 98--120.


B.S. Baker, An Algorithm for Structuring Programs: Extended Abstract, Proc. 3rd ACM Symposium
on Principles of Programming Languages, January 1976, pp. 98-120.


(I'm suspicious of the identical page numbers...)


Her struct tool was distributed with 7th Edition Unix, but wasn't maintained.
