)NS creates a global namespace and displays its full name, nm.
nm may be either a simple name or a compound name separated by '.', including one of the special names '#' (Root) or '##' (Parent).
If name does not start with the special Root space identifier '#', the new namespace is created relative to the current one.
If name is already in use for a workspace object other than a namespace, the command fails and displays the error message Name already exists.
If name is an existing namespace, no change occurs.
)NS with no nm specification displays the current namespace.
