Without knowing exactly how this was done on the Miggies, and the level of
security we have here compared to zero on the amiga because of its flat, no
mmu memory mapping, precludes my having a thought to argue about it in my
wildest dreams.
Re ARexx, its biggest Achilles heel was the Rexx.lib, which became so
obvious that Joanne Dow and someone else whose name I've spaced in the
ensuing 15 years, actually dissed it, found several buglets and one real
whoodoozy and fixed them, which enhanced the amiga's long term stability
such that even the web server only had to be rebooted at 2 to 3 week
intervals. Yes, that Joanne Dow, you might remember the name from her bix
days, is a friend of mine. Quite a Lady IMO. About as creative as anyone
I've ever met in coming up with lady-like versions of screw you etc. ;-)
Last I knew a year back up the log, she was still working, I don't have too
many years on her, and my use by date has passed a long time ago Dennis,
I'll be 79 on the next 4th.

And that, despite being mostly written in Lisp, worked very well. The fact
that for every board initialized at boot time required a soft reboot that
the user wasn't made obviously aware of, could get interesting though.
Cheers, Gene
