Direct Access to Element in a Vector Array?

[Anonymous]

what's the correct way to do this?
vector arrays aren't described in the doc's

vector $vector[];
$vector = <<0, 0, 0>>;

//want to do
xform -t -os ($vector.x) ($vector.y) ($vector.z) mesh.vtx;
//syntax error! WTF?

vector $vector;
$vector = <<0, 0, 0>>;

//want to do
xform -os -t ($vector.x) ($vector.y) ($vector.z) mesh.vtx;
