data input from keyboard

[Mauro La Salete Costa Lima de Araujo <mscla@...>]

Hi people,
I'm trying to write a simple program in Lua, but it's getting hard for me
to work with data input from keyboard. I've tryed to use de function
"read()" but I always get the following message:

../lua-5.0/bin/lua: teste.lua:2: attempt to call global `readfrom' (a nil
value)
stack traceback:
        teste.lua:2: in main chunk
        [C]: ?

 can anyone help me?
