TCL script retrieve Part attributes question from new guy in OrCAD

I am trying to retrieve all the parts and their attributes in OrCAD Capture Design. I do get all the data by using the script below. But when I output the vaules from $lName and $lDeviceDesignator, the values are not what I expected, just like R123, C456 for Designator. I got the internal code like _203b8f0e_p_CString for Designator and _70228f0e_p_CString for Name. How can I get the real vaules, lsuch as R123, C456? Thank you.

 #-----------------Get Part Attributes

#get the name 

set lName [DboTclHelper_sMakeCString] 

$lPlacedInst GetName $lName

#get the device designator 

set lDeviceDesignator [DboTclHelper_sMakeCString] 

$lPlacedInst GetReferenceDesignator $lDeviceDesignator
