Magic File Array

[RWK at MIT-MC (Robert W. Kerns)]

Alright, where do you hide it.
MSGFILES is '(T), TYO is CONSOLE-OUTPUT, I do
(TYO 5 FOO)
and it does
;<mumble> LOSING OUTPUT FILE

OK, so where is the output file that it writes the <mumble> to?
It's certainly not going through TYO, unless it's on a character-by-character
basis!
