Identifying Current Collector

Hi all,

i had created the collector with some variable name.

set NAME1 Elements1

*collectorcreateonly comps '$NAME1' '' 3

now i want to catch the name of the created collector or identify the current collector which is just created.

i am trying to catch the name through string ($NAME1) but collector is not coming its just an string.

even searched the through-out the libraries for catching current collector.
