Need help with a script.

I have an object that needs to be moved more than ten meters down. (Its a warp core from Star Trek) And the script I'm using has a 10m movement limitation. So I need some help, knowing what function to use instead of llSetPos. Thanks.

(I should point out, this was modified from a dorr script, so ignore the references to doors...)

default
{
    state_entry()
    {
        llListen(74777, "Warp Core Controls", NULL_KEY, "ejectWarpCore");
        llListen(74777, "Avalon Ziplon", NULL_KEY, "ejectWarpCore");
    }
    
    listen(integer iChannel, string strName, key kID, string strMsg)
    {
        vector vClosed = <159.534, 145.682, 867.212>;
        vector vOpen = <159.534, 145.682, 856.037>;
                        
        if (llGetLocalPos() == vClosed)
        {
            //Door is Closed, open it
            llSetPos(vOpen);
        }
        else if (llGetLocalPos() == vOpen)
        {
            //Door is Open, close it
            llSetPos(vClosed);
        }
        else
        {
            //Door is neither Open nor Closed
            //Assume an error has occured and reset door to default location
            llSetPos(vClosed);
        }
    }
}

at this site you have 3 different functions. Each of them can warp from anywhere to anywhere within a region faster than you can wink an eye

One way would be this:

PosJump(vector target_position)
{
    llSetPrimitiveParams([PRIM_POSITION, <1.304382E+19, 1.304382E+19, 0.0>, PRIM_POSITION, target_position]);
}

default
{
    state_entry()
    {
        llListen(74777, "Warp Core Controls", NULL_KEY, "ejectWarpCore");
        llListen(74777, "Avalon Ziplon", NULL_KEY, "ejectWarpCore");
    }

    listen(integer iChannel, string strName, key kID, string strMsg)
    { 
        vector vClosed = <159.534, 145.682, 867.212>; 
        vector vOpen = <159.534, 145.682, 856.037>;

        if (llGetLocalPos() == vClosed)
        {
             //Door is Closed, open it
             PosJump(vOpen);
        }
        else if (llGetLocalPos() == vOpen)
        {
             //Door is Open, close it
             PosJump(vClosed); 
        }
        else
        {
             //Door is neither Open nor Closed
             //Assume an error has occured and reset door to default location
             PosJump(vClosed);
        }
    }
}
