For anyone concerned about performance, using a transform object is
significantly faster that going the match transformation route. Also, check
out the AddNull() method. It creates a new null as the child of the object
that calls it:

// Create a normalized transform
var trans = XSIMath.CreateTransform;

// Loop through the selection
for(var e = new Enumerator(selection); !e.atEnd(); e.moveNext()){

// For each obj, add a null
var obj = e.item();
var node = obj.AddNull(obj.name + '_NUL');

// Transform the null to rest pose
node.kinematics.local.transform = trans;
}

For anyone concerned about performance, using a transform object is
significantly faster that going the match transformation route. Also,
check out the AddNull() method. It creates a new null as the child of the
object that calls it: 
// Create a normalized
transform 
var trans =
XSIMath.CreateTransform; 
// Loop through
the selection 
for(var e = new
Enumerator(selection); !e.atEnd(); e.moveNext()){ 
   
// For each obj,
add a null 
    var obj =
e.item(); 
    var node = obj.AddNull(obj.name + '_NUL'); 
   
// Transform the
null to rest pose 
   
node.kinematics.local.transform = trans; 
} 
 
<blockquote type=cite class=cite cite="">From
the online help: 
(select a word in your script and click the ? button in the script
editor, it ll give your the appropriate info) 
  
Scripting Syntax 
GetPrim (PresetObj, [Name], [Parent], [Primitive])<a name="wp659811"></a>
 
  
  
so the 
GetPrim
"Null" line would become
something like: 
GetPrim "Null" , nill & "_null" 
  
now there is also the MatchTransform
command, 
that will allow to match the transforms of the null to the object, 
to avoid doing a constraint and then removing it 
and then the ParentObj command to do the parenting. 
Something like: 
  
-- ------ 
set A=GetValue("SelectionList") 
    for each ab in A 
        GetPrim "Null", ab
& "_null" 
        MatchTransform , ab,
siSRT 
        ParentObj ab &
"_null", ab 
    next 
-- ---- -- 
  
that should do the trick. 
You didnt want any constraints in the end right?
