Warnier-Orr diagrams were created by Jean-Dominique Warnier in France and
Ken Orr in the US. The are typically included in the "DSSD" (Data  Structured
Systems Development) methodology. I have found them hard to use to represent
"break" and "continue" as well as "if ((c = getchar()) != EOF)".

To slightly change the subject, has anyone out there used the full DSSD
or other design approaches (such as Yourdon) for UNIX/C programs? I am a
part of a project looking at this and I have heard little but vendor claims.
Even biased testimonials (positive or negative) would be appreciated but
I'd really like to hear about any comparative studies.
