#ARexx ... I never saw or touched an #Amiga, so everything I've heard about ARexx is hearsay.

I have used Regina #Rexx (which I think is pretty close to the ANSI standard for the language) and #OORexx and should probably renew my acquaintance. But I found Regina punted too often to the shell / environment. If I wrote a script and tried to use it on two different computers, it often failed because so much depends on throwing unknown commands upstream.

Later scripting languages have a more full set of built-in commands, so they can run reliably on a wider variety of systems.

I never fully adapted to stem variables, either. I think I would have liked them better if the language also had regular arrays and dictionaries (keys and values).
