The FREE statement is used to release resources from STORE statements or SAVE= options. If you save a result table (one table or sets of tables) with the SAVE= option in any of the analytic statements of the IMSTAT procedure, then you can release the resources with the FREE statement. Once a table has been freed, you can reuse the table name. While a saved table exists, you cannot create a table by the same name.
