[Closed] Hard Times with cloth modifier groups

well , it seems that cloth modifier in max has some restrictions , here is what i want to do:
1-i want for an object with cloth and groups applied to ,to list existent groups with names , vertex assigned to each group, constraint type and properties
this is for now seems to me unclear

2- i want to make a group with preserve type of constraint here what i wrote

  $.modifiers[1].makePointGroup  #{1..20} $pillar  "lolo"
  $.modifiers[1].makeConstraint "lolo" "Preserve"  $pillar  

and what i got is that : – Runtime error: No such constraint type: Preserve !

so any help ?
