Could it be a pointer to a 'Point'?

Try creating a variant array of bytes using VarArrayCreate,
then move the memory occupied by a variable of type TPoint
into the variant array.

var
  v: variant;   //or OleVariant ?
  pv: pointer;
  pnt: TPoint;
begin
  v := VarArrayCreate([0,SizeOf(TPoint)-1]....
  pv := VarArrayLock(v);
  pnt.x := 100;
  pnt.y := 200;
  Move(pnt,pv^,SizeOf(TPoint));
  VarArrayUnlock(v);
  ActiveDocument.getEntityFromPOINT(v);
end;

Found that simply using
 ActiveDocument.getEntityFromPOINT(VarArrayOf(100, 200));
works just fine.
