LLsetpos but ... Match Rotation?

Spent more time than I'm going to admit to- making a follower prim script, the one thing that I can't grasp is how to match the rotation of the prim being followed. A push in the right direction?

-----------------------
Prim to be Followed:
-----------------------

vector oldpos;

default
{
    state_entry()
    {
        llSleep (0.25);
        llSetTimerEvent ( 5 );
    }
    timer()
    {
        vector pos = llGetPos();
        
        if ( oldpos != pos )
        {
            llRegionSay ( 10482, (string)pos );
            oldpos = pos;
        }
    }
}

---------------------------
Follow That Prim Script:
---------------------------

default
{
    state_entry()
    {
       llListen ( 10482, "", "", "" );
    }
    
    listen ( integer chan, string name, key id, string arg )
    {
        llSetPos ( (vector)arg );
    }

}

(digging in the wiki now-)

Try this:

// sending script
llRegionSay(CHANNEL, llList2CSV([ llGetPos(), llGetRot() ]));

///receiving script
list params = llCSV2List(message);
vector pos = (vector)llList2String(params, 0);
rotation rot = (rotation)llList2String(params, 1);
