I haven't tried this yet but it's definately better than what I originally=

But I did try this. I don't think your usage of readline is correct. ri=20
tells me that readline takes a single parameter and it's the line seperator=
.=20


I suppose you meant this:

while (print prompt; ans =3D readline)
handle_action(ans)
end

No way to do it. If you believe STDIN is connected to tty, you

Thanks for the tip. I'll stick to the fixed up while loop.
