Structured Programming with Warnier-Orr Diagrams - Part 1 (.wpd / .rtf)
Article from the December 1977 BYTE magazine written by David A. Higgins, "Any successful program design methodology must be able to do several things: it must produce consistent, low cost, high reliability results; it must produce them quickly, while still allowing for easy maintenence later and, it must be simple enough to allow anyone (and I do mean anyone) to use it. Warnier-Orr diagrams (after Jean Dominique Warnier in France and Kenneth T Orr in the United States) satisfy all of the above requirements with an added bonus; they produce structured programs that nearly always run correctly at the first effective trial. They allow people to produce superprograms without being superprogrammers".


Structured Programming with Warnier-Orr Diagrams - Part 2 (.wpd / .rtf)
Part 2. Written by David A. Higgins. From the January 1978 BYTE magazine. - See also "Warnier-Orr Structured Progamming Approach" by the same author.

CP/M

CP/M Checklist Part 1 - by Commodoreman
This is an article where I continue from the Rediscovery series to one
of discovery. I made a checklist of things I would like to know and in
these series I write about what I have found out. This is a good source
of information for those who have CP/M available, but either do not have
the resources or know quite where to start. This article will be
available after it has been published by Commodorefree.


Rediscovering CP/M Part 1 (.rtf) (.zip)
This is an article about my return to CP/M mode on the Commodore 128.
This is the first of four rediscovery articles (of which I also
made available to Commodorefree for publication). This article can also be
found in the Commodorefree magazine, issue 59.


Rediscovering CP/M Part 2 (.txt) (.wpd)
This is an article about my return to CP/M mode on the Commodore 128.
This is the second of four rediscovery articles (of which I also
made available to Commodorefree for publication). This article is also
available in Commodorefree, issue 60.


Rediscovering CP/M Part 3 (.txt) (.wpd)
This is an article about my return to CP/M mode on the Commodore 128.
This is the third of four rediscovery articles (of which I also
made available to Commodorefree for publication). This article has been
published in Commodorefree, issue 61 and will be made available here soon.


Rediscovering CP/M Part 4 (.txt) (.wpd)
This is an article about my return to CP/M mode on the Commodore 128.
This is the fourth of four rediscovery articles (of which I also
made available to Commodorefree for publication). This article will be
available here after it has been published by Commodorefree. I expect this
article to be released in issue 62.
