close a PersistentTable connection
PersistentTable object created with the Open command
The Close command disconnects a PersistentTable object from its connected database file and releases the associated resources.
Persistent tables are in general thread safe as of Maple 2021; see the Thread Safety section of the PersistentTable overview page for more details and caveats.
For more information on thread safety, see index/threadsafe.
