Help MELscript - component editing

WaYWO

Hi,
my question is how would you move a shell of components at a given position in world space coordinates? And how to change the pivot point of selected component by Mel ? every commands I have tried has been ignored by maya but are actually valid. Is there a work around for that? When moving components in relative(-r) it works of course...

manipPivot -p repositions the gizmo of your component selection in world space.
xform -ws -piv repositions the gizmo of your object selection in world space.

I don't think there's a way to move a shell selection to world space with a single command that also retains component spacing.
