The RemovePermanent command removes the permanent entry for which key is the key.  The cache table can be given directly as cache, or cache can refer to a procedure that has, or can have, a cache remember table.  If such a procedure is given and it has a cache remember table, the permanent entry is removed from that table.  If the procedure does not have a table, no action is taken.

To handle an expression sequence as a key, key must be given in a list.  The actual key used for the entry is op(key).

Calling RemovePermanent is the only way to remove a permanent entry from a cache table.

To add a permanent entry to a cache table, use AddPermanent.

For more information on cache tables, see Cache Package.
