change llSitTarget coords via listen command?

I have a teleporter that sends to multiple destinations. The destination is changed by telling it through a channel the new coordinates, or that is the idea. I do not know how to get llListen to pick up the vector coordinates rather than a string message. Would it be easier to split them up into pos.x, pos.y and pos.z, send them one at a time, and then reassemble in the teleport script?

(The coordinates are stored in a controller on the HUD and when you click one, it would set the teleporter's destination.)

type cast what is said into a vector

the following example works only if the input is given in a "<x,y,z>" format. I believe if some other value is given that typcasting sets it to the zero equivalent for whatever variable class it is typecasting to:

listen(integer channel, string name, key id, string message)
{
    vector destination = (vector)message;
    if(destination==<0,0,0> && (string)destination!=message)//checks if the ZERO_VECTOR value was intentional or the cause of an invalid vector.
    {
        llInstantMessage(id,"You entered an invalid set of coordinates");
    }
    else
    {
        llInstantMessage(id,"Changing target to " + message + ".");
        llSetSitTarget(newdestination,ZERO_ROTATION);
    }
}

*note I did not test this in-game so I cannot garauntee that this will work and/or compile, but it should give a good idea of how to go about setting up a listen.

**I see that these coordinates are being broadcast from a HUD. in that case you would want to change the "id" in the llInstantMessage to "llGetOwner(id)" so that the IM goes to the owner of the HUD.

Type-casting a string to a vector can be tricky. I think what's posted above is close, but I'm pretty sure (I'm at work so like the above poster I cannot verify atm) that you would have to parse the string to a list, and then type-cast each value of the list as a float, then save that to a vector.

they changed it so a simple typecast of string to vector works now. there's a blurb at the end of here about it.
