A Discipline of Programming by E.W. Dijkstra (1976)

VVIV, VVV, VVVI

VVI, VVII, VVIII,

I agree. The most important thing for code now is to be maintainable, and that means easy to read and understand. Also tests are important to take keep it from breaking. While it is good practice to write code that is not wasteful of resources, this is something that can be improved after the code and tests are written.

Now hex values in roman numerals would be impressive: ..., VIII, VIV, VV, ...

VMS had a simple but effective versioning system. It saved the previous versions of the file in the file syetem with a version number so you could easily go back. You could set the number of versions to keep.

What is this weird value? Why are fractions being mixed with decimals? How about 0.75 cents? 75 hundredths of a cent? Three quarters of a cent?

I can find no source, open or otherwise.

I can also find no mention of the standards that are being used.
