|a program statement from yesteryear: 12 MAG(J,K) = 0|
|a whole program; no idea what it does|
Frequent saving was ingrained in my workflow by the time applications came uniformly equipped with Ctrl-S. (Saving without exiting. Luxury!) Every time I would pause to think what to write next, in word processor, spreadsheet, or text editor, I would automatically hit Ctrl-S. It's now an automatic behaviour.
But modern applications no longer use Ctrl-S. They just continually save, automatically. There's no need to keep saving explicitly. Most applications that have an auto-save feature also let you do your own saves in between. But some applications no longer have a user save command at all. I noticed this first with Evernote, and then with Google Docs.
Fortunately, these applications haven't mapped Ctrl-S to any other function (mail programs where Ctrl-S means "send" are a real nightmare), so nothing bad happens if I do reflexively hit Ctrl-S. Which I do sometimes, because it feels really weird not to keep saving after all these years.
Three generations of saving technology: manual-slow-and-clunky, manual-easy, automatic. That's probably progress.
