Nice flame bait. Are you sure you're not quoting from the "Good Times"
text?

Aha. First time I see anything related to this putative bug, that can
be tested. Ok, here we go.
In BioMOO, I type:
;fileread("",".")
=> {""}
[used 2 ticks, 0 seconds.]
Anyone else managed to crash the MOO doing that?

;fileread("",";:<<>' \"|")
=> {""}

Good that this works for you.

Sounds like an improvement.

Looks like your system is not compatible with FUP. We don't have here
any Pentium Pro's with linux to create a special version for you,
sorry. You'll either have to fix it yourself, or live without it. Or
change OS.
