Summary

Function: vector llGetRegionCorner( );

Returns a vector in meters that is the global location of the south-west corner of the region the object is in. The z component is 0.0

Divide the returned value by 256 to get the region offset.

Examples

//calculates your position relative to <0,0,0> of 'Da Boom' in meters when you touch it
vector vecrel; //a sum of llgetpos and llgetregioncorner (and another vector). Saving time doing vector math.
default
{
    state_entry()
    {
        llSetText("Touch me to get your position", <1,1,1>, 2.0);
    }
    touch_start(integer total_number)
    {
        vecrel = llGetRegionCorner() + llGetPos();
        llWhisper(0, "llGetRegionCorner() is:"+(string)vecrel ); //for debugging before vector addition
        vecrel.x = vecrel.x - 256000;
        vecrel.y = vecrel.y - 256000;
        llWhisper (0, "Position relative to <0,0,0> of 'Da Boom': "+ (string)llRound(vecrel.x) +",                "+ (string)llRound(vecrel.y) +",              "+ (string)llRound(vecrel.z) + ".");
        llWhisper(0, "Position relative to <0,0,0> of 'Da Boom':"+(string)vecrel ); //faster but unformatted output
    }
}

Notes

The great zero is at region offset <1000,1000>, Great Zero🖈
