> Through AREXX any application could control any other application, which is something Windows and OSX still don't really do. I mean to some extent it's sort of possible now, but not as easily as it was with Amiga OS.
AppleScript was introduced in System 7.1.1 back in 1993. Maybe ARexx scripting was much better, I don't know.
(Support for scriptable Macintosh applications actually arrived in 1991, but there was no built-in scripting language for it.)
