FREE dobj.
Effect
The FREE statement deletes all rows from an internal table and releases the memory area that the rows occupied.
On other data objects, the FREE statement functions like the CLEAR statement.
If dobj is a structure with components with a tabular form, the memory of all the tabular form components will be released.
