a small example of an on and off switchable listen by use of llListenControl()

integer handle;
integer toggle;
default
{
    state_entry()
    {
        handle = llListen(5, "", NULL_KEY, "");    // Establish a listener to listen to anything on channel 5 ...
        llListenControl(handle, FALSE);            // ... but make the listener inactive for now
        llSetText("not listening", <0.0,0.0,0.0>, 1.0);
    }
 
    touch_start(integer total_number)
    {
        toggle = !toggle;
        llListenControl(handle, toggle);           // Make the listener active or inactive as required
 
        if(toggle)
        {
            llSay(0, "now listening on channel 5");
            llSetText("listening on ch 5", <1.0,0.0,0.0>, 1.0);
        }
        else
        {
            llSay(0, "not listening any more");
            llSetText("not listening", <0.0,0.0,0.0>, 1.0);
        }     
    }
 
    listen(integer channel, string name, key id, string message)
    {
