[Closed] Position constraint equivalent in Maxscript

Hey there
How to get the position constraint effect But with maxscript.
I mean ,if we use position con to an object and the object has a parent.
The parent position doesn’t effect on the child anymore

A = point pos:[100,00,0]  size:100 wirecolor:red
B =   sphere parent:A
C = point pos:[0,00,0] size:100
Po_Scr = b.pos.controller=position_script()
Po_Scr.AddNode "POSCON" C
Po_Scr.script = "POSCON.pos"
/*
Pc = Position_Constraint()
B.position.controller = Pc
Pc.appendtarget C 100
