Five Sample D-Charts
(from a 1980s R&D project)


D-Charts #1 and #2

The first two graphs of the simple SCOMPENSATE routine are an example of our evolving charting style as we continued to adapt the D-chart format for a specific use.

First version:



Second version:




D-Chart #3

The 2-page graph for the UART routine is an example of an incomplete, quick-and-dirty sketch produced during a meeting by someone who drew even worse then than she does now. But the sketch produced in the midst of a “brainstorming” session was still good enough to establish the beginning pattern of logic for final coding and documentation.

Continuation page (branching line from “Decrement receive word count”):




D-Charts #4 and #5

The two charts labeled Figure IV-15. and Figure IV-16. are from the published documentation for the project. The artwork is admittedly still quite crude, having been produced with a ruler along with what was then considered a state-of-the-art daisy-wheel printer.

Figure IV-15 (pg. IV-39 of manual):
