WordStar. Or at least its clone, the alter-ego of 'joe' ('jstar'). I've been imprinted with WordStar since the mid-1980s, I have even renamed 'jstar' to 'ws'.

WordStar. Or at least its clone, the alter-ego of 'joe' ('jstar'). I've been imprinted with WordStar since the mid-1980s, I have even renamed 'jstar' to 'ws'. So it's real Wordstar on CP/M. And its clone, 'jstar' on Linux.
