{title:Description}

{pstd}
Returns the {help nodeid:nodelab} of a node given its {help nodeid}. Results are also stored
in the return vector. When no node with the specified id is found in network {it:netname} and error is thrown.
This command is mostly used for programming with networks.


{title:Stored results}

	Scalars
	  {bf:r(nodeid)}	nodeid of node
	  
	Macros:
	  {bf:r(netname)}	name of the networks
	  {bf:r(nodelab)}	node label of the node
