Examples

//This is just an example script, you shouldn't handle touches within single script this way.

default
{
    touch_start(integer c)
    {
        llMessageLinked(LINK_THIS, 0, llDetectedName(0), llDetectedKey(0));
    }
    link_message(integer source, integer num, string str, key id)
    {
        llWhisper(0, str + " (" + (string)id + ") touched me!");
    }
}

Useful Snippets

// This is just an example script, you shouldn't handle link message within single script this way.

default{ // To propagate an unlimted number of arguments of any type.
	// Presumed, the separator string isn't used in any source string!
    state_entry() {    
        list my_list = [1, 2.0, "a string", <1, 2, 3>, <1, 2, 3, 4>, llGetOwner()];  
        string list_parameter = llDumpList2String(my_list, "|");	// Typecast list to a string
        llMessageLinked(LINK_THIS, 0, list_parameter, NULL_KEY)
    }

    link_message(integer sender_num, integer num, string list_argument, key id) {
        list re_list = llParseString2List(list_argument, ["|"], [""]);	// Typecast string back to a list
    }    
}
