I used to think (Open)VMS would have been a potential platform for an
effective ADDRESS command. Where ARexx used a shared memory linked-list for
the "port" (as I'd stated, avoiding copying of data), (Open)VMS had
"mailboxes" (they would have to copy data -- or at best remap the virtual
memory from one process to another) which could serve the same purpose;
receiving application creates/owns the named mailbox, sending applications
would provide the data packet including a return mailbox link.

Yeah, that was the other feature -- anything that could not be parsed
as a REXX statement was automatically sent to whatever the current ADDRESS
host happened to be.
