How to slection node by set in hyperview

Hi:

In GUI of hyperview, it is possible to get the query result by node set which I created in hypermesh.

Now I am trying to program this process by tcl/tk but I don't know which command can achieve it.

I have read the command 'poISelectionSet Add' but it can't choose by the set which I created in hypermesh.

Has anyone done this before or have any ideas of how to do this?

Thanks

Kai
