Linked_XForm : Modifier

Linked_XForm - superclass: modifier; super-superclass:MAXWrapper - classID: #(806195, 0) 

linked_xform ... LinkedXForm ... 

<Linked_XForm>.backTransform BooleanClass default: true -- boolean; Back_Transform

<Linked_xform>.Control Node default: undefined Object that the vertices are linked to. When transformed, the vertices follow.

Note: In 3ds Max 4.2, an FPS interface was added to the Linked XForm modifier to expose a 'control' property, and the PB2 'control' property was hidden from MAXScript. Setting the control node with MAXScript now updates the internal offset matrices. Results can be unpredictable if the modifier is applied to multiple nodes since you aren't sure which of the nodes will be used when calculating the internal matrices.
