In the 80s, I implemented the use of VAX Code Management System (CMS) on a large commericial avionics software project. Made me a little more confident when later flying a particular Boeing plane.
I had been at Purdue when Walter Tichy built RCS. I discovered in my first job that businesses lagged the state of the art more than I ever imagined.
On the other hand, I was later at Rational who then bought ClearCase. Argh...
I was convinced that VMS's versioned files thing was DEC's cunning plan to sell more disk drive space (though I didn't and still don't know what the underlying mechanism was) - I was quite glad when I learned how to turn it off, though.
Versioned files existed in Tenex, developed by Bolt Beranek and Newman in the early 1970s; version numbering was based on a similar feature in MIT's Incompatible Timesharing System. DEC's variant of Tenex was eventually called TOPS-20. Many features of VAX/VMS were influenced by Tenex/Tops-20.
