# Nonqualified Names as Lookup Names

You may also use nonqualified names to look up a coordinate space that already exists in the tree. During lookup a search is conducted for the given NQ name, starting at the root space and extending recursively through all child spaces. If the NQ name is found exactly once during the search the found space is the unique, desired space. Errors result if the name is not found or if the name is found more than once.
