default {
    state_entry()
    {
        llSay(0,"This is an incredibly useless program." );
    }
}

Notes

If one object 'says' something to another object (e.g., a button that, when touched, turns on a lamp), it is a good idea to use a very negative channel, e.g.,

    llSay(-5243212,"turn on");

It is impossible for an avatar to chat on a negative channel, and extremely unlikely that some other object would accidently say something on such a channel. (Of course, the intended target of the message must be set to 'listen' on this channel.)

If DEBUG_CHANNEL is used as channel, the script will say msg to the Script Warning/Error window. (DEBUG_CHANNEL = 2147483647)

If 0 is used as channel, the script will say msg so anyone can see it as normal chat. All other integers used are private channels.
