    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("",";:<<>' \"|")

    => {""}

    [used 2 ticks, 0 seconds.]

    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.
