before WordStar, there were line editors
Back in the late 1980s, the Marine Corps had decided that they were going to standardize the applications that all of their PCs used.
Most of those had actually been acquired by piggybacking on an Air Force contract. Purchasing tens of thousands of Zenith 286 systems that came with DOS 3.3, WordStar, and Windows 1.02R. And many units bought their own systems, so there was a hodge-podge of different programs being used.
But in their brilliance, they decided to standardize on Enable. That is a long forgotten company, but they were one of the very first to offer an "Office Suite". A word processor, a spreadsheet, and a database. So from a cost perspective, it was a lot cheaper.
However, the quality of each of those programs was very inferior and a lot of units outright ignore the orders to change. WordStar units still used WordStar, MultiMate units still used MultiMate, WordPerfect units still used Word Perfect, etc.
And during that time, I told some of the guys I worked with that the Marine Corps had finally listened, and were dumping Enable and switching to a new Corps wide word processor.
Edlin.
For those that do not know, that was a line editor built into DOS. It was largely junk, and really only good for making or editing batch files or things like autoexec.bat and config.sys. There were 4 or 5 others there, and only my friend got the joke. The others were all confused as they had no idea what Edlin even was.
