@balglaas The last time I wanted edlin was in 1999, when my only PC was a Windows laptop. When I upgraded to XP in '04, I became frustrated because edlin only works in qwerty, even when Windows CMD uses another keyboard layout.
In the Unix & Linux worlds, I've made ed my main editor, with vi and nano as fallbacks. It's the only editor I use where I don't have to worry about incompatible terminals or terminal oddities, & where the only feature I might miss is syntax highlighting.
